+Introduction
+^^^^^^^^^^^^
+
+ .. container:: sectionbody
+
+ .. container:: paragraph
+
+ Consider a scenario where a supermarket chain called
+ *HyperM* controls how it sells items in a policy-based
+ manner. Each time an item is processed by *HyperM*'s
+ point-of-sale (PoS) system an event is generated and
+ published about that item of stock being sold. This
+ event can then be used to update stock levels, etc..
+
+ .. container:: paragraph
+
+ *HyperM* want to extend this approach to allow some
+ checks to be performed before the sale can be
+ completed. This can be achieved by requesting a
+ policy-controlled decision as each item is processed
+ by for sale by each PoS system. The decision process
+ is integrated with *HyperM*'s other IT systems that
+ manage stock control, sourcing and purchasing,
+ personnel systems, etc.
+
+ .. container:: paragraph
+
+ In this document we will show how APEX and APEX
+ Policies can be used to achieve this, starting with a
+ simple policy, building up to more complicated policy
+ that demonstrates the features of APEX.

+
+ .. rubric:: Sales Decision Event
+ :name: sales_decision_event
+
+ .. container:: paragraph
+
+ Each time a PoS system processes a sales item an
+ event with the following format is emitted:
+
+ .. table:: Table 1. Sale Input Event
+
+ +----------------------+----------------------+-----------------------+
+ | Event | Fields | Description |
+ +======================+======================+=======================+
+ | SALE_INPUT | time, sale_ID, | Event indicating a |
+ | | amount, item_ID, | sale of an item is |
+ | | quantity, | occurring |
+ | | assistant_ID, | |
+ | | branch_ID, notes, … | |
+ +----------------------+----------------------+-----------------------+
+
+ .. container:: paragraph
+
+ In each ``SALE_INPUT`` event the ``sale_ID`` field
+ is a unique ID generated by the PoS system. A
+ timestamp for the event is stored in the ``time``
+ field. The ``amount`` field refers to the value of
+ the item(s) to be sold (in cents). The ``item_ID``
+ field is a unique identifier for each item type,
+ and can be used to retrieve more information about
+ the item from *HyperM*'s stock control system. The
+ ``quantity`` field refers to the quantity of the
+ item to be sold. The ``assistant_ID`` field is a
+ unique identifier for the PoS operator, and can be
+ used to retrieve more information about the
+ operator from the *HyperM*'s personnel system.
+ Since *HyperM* has many branches the ``branch_ID``
+ identifies the shop. The ``notes`` field contains
+ arbitrary notes about the sale.
+
+ .. container:: sect2
+
+ .. rubric:: Sales Decision Event
+ :name: sales_decision_event
+
+ .. container:: paragraph
+
+ After a ``SALE_INPUT`` event is emitted by the PoS
+ system *HyperM*'s policy-based controlled sales
+ checking system emits a Sale Authorization Event
+ indicating whether the sale is authorized or
+ denied. The PoS system can then listen for this
+ event before continuing with the sale.
+
+ .. table:: Table 2. Sale Authorisation Event
+

+ | Event | Fields | Description |
+ +======================+======================+=======================+

+ | | assistant_ID, | |
+ | | branch_ID, notes, | |
+ | | message… | |
+ +----------------------+----------------------+-----------------------+
+
+ .. container:: paragraph
+
+ In each ``SALE_AUTH`` event the ``sale_ID`` field
+ is copied from the ``SALE_INPUT`` event that
+ trigger the decision request. The ``SALE_AUTH``
+ event is also timestamped using the ``time`` field,
+ and a field called ``authorised`` is set to
+ ``true`` or ``false`` depending on whether the sale
+ is authorized or denied. The ``message`` field
+ carries an optional message about why a sale was
+ not authorized. The other fields from the
+ ``SALE_INPUT`` event are also included for
+ completeness.
+
+ .. container:: sect2

+
+ The database table ``ITEMS`` has a row for each
+ items that *HyperM* sells. Each item is identified
+ by an ``item_ID`` value. The ``description`` field
+ stores a description of the item. The cost price of
+ the item is given in ``cost_price``. The barcode of
+ the item is encoded in ``barcode``, while the item
+ supplier is identified by ``supplier_ID``. Items
+ may also be classified into categories using the
+ ``category`` field. Useful categories might
+ include: ``soft drinks``, ``alcoholic drinks``,
+ ``cigarettes``, ``knives``, ``confectionery``,
+ ``bakery``, ``fruit&vegetables``, ``meat``, etc..

+
+ *HyperM* operates a number of branches. Each branch
+ is described in the ``BRANCHES`` database table.
+ Each branch is identified by a ``branch_ID``, with
+ a branch name given in ``branch_Name``. The address
+ for the branch is encoded in ``street``, ``city``,

+
+ For the first version of our policy, let’s start
+ with something simple. Let us assume that there
+ exists some restriction that alcohol products
+ cannot be sold before 11:30am. In this section we
+ will go through the necessary steps to define a
+ policy that can enforce this for *HyperM*.
+

+New Policy Model
+----------------
+
+ .. container:: sectionbody
+
+ .. container:: sect1
+
+ .. rubric:: Create the an new empty Policy Model ``MyFirstPolicyModel``
+ :name: create_the_an_new_empty_policy_model_code_myfirstpolicymodel_code
+
+ .. container:: paragraph
+
+ Since an organisation like *HyperM* may have many
+ policies covering many different domains, policies should
+ be grouped into policy sets. In order to edit or deploy a
+ policy, or policy set, the definition of the policy(ies)
+ and all required events, tasks, states, etc., are grouped
+ together into a 'Policy Model'. An organization might
+ define many Policy Models, each containing a different
+ set of policies.
+
+ .. container:: paragraph
+
+ So the first step is to create a new empty Policy Model
+ called ``MyFirstPolicyModel``. Using the APEX Policy
+ Editor, click on the 'File' menus and select 'New'. Then
+ define our new policy model called
+ ``MyFirstPolicyModel``. Use the 'Generate UUID' button to
+ create a new unique ID for the policy model, and fill in
+ a description for the policy model. Press the ``Submit``
+ button to save your changes.

+
+ Using the APEX Policy Editor, click on the 'Events' tab.
+ In the 'Events' pane, right click and select 'New':
+
+ .. container:: imageblock
+
+ .. container:: content
+
+ |Right click to create a new event|
+
+ .. container:: paragraph
+
+ Create a new event type called ``SALE_INPUT``. Use the
+ 'Generate UUID' button to create a new unique ID for the
+ event type, and fill in a description for the event. Add
+ a namespace, e.g. ``com.hyperm``. We can add hard-coded
+ strings for the ``Source`` and ``Target``, e.g. ``POS``
+ and ``APEX``. At this stage we will not add any parameter
+ fields, we will leave this until later. Use the
+ ``Submit`` button to create the event.
+
+ .. container:: imageblock
+
+ .. container:: content
+
+ |Fill in the necessary information for the
+ 'SALE_INPUT' event and click 'Submit'|
+
+ .. container:: paragraph
+
+ Repeat the same steps for a new event type called
+ ``SALE_AUTH``. Just use ``APEX`` as source and ``POS`` as
+ target, since this is the output event coming from APEX
+ going to the sales point.
+
+ .. container:: paragraph
+
+ Before we can add parameter fields to an event we must
+ first define APEX Context Item Schemas that can be used
+ by those fields.
+
+ .. container:: paragraph
+
+ To create new item schemas, click on the 'Context Item

+
+ .. TIP::
+
+ .. container:: paragraph
+
+ APEX natively supports schema definitions in ``Java`` and ``Avro``.
+ ``Java`` schema definitions are simply the name of a Java Class. There are some restrictions:
+
+ .. container:: ulist
+
+ - the class must be instantiatable, i.e. not an Java interface or abstract class
+
+ - primitive types are not supported, i.e. use ``java.lang.Integer`` instead of ``int``, etc.
+
+ - it must be possible to find the class, i.e. the class must be contained in the Java classpath.
+
+ .. container:: paragraph
+
+ ``Avro`` schema definitions can be any valid `Avro <https://avro.apac
+ he.org/docs/current/spec.html>`__ schema. For events using fields defined with
+ Avro schemas, any incoming event containing that field must contain a value that conforms to the Avro schema.

+
+ .. container:: paragraph
+
+ APEX policies are defined using a state-machine model.
+ Each policy comprises one or more *states* that can be
+ individually executed. Where there is more than one
+ *state* the states are chained together to form a
+ `Directed Acyclic Graph
+ (DAG) <https://en.wikipedia.org/wiki/Directed_acyclic_graph>`__
+ of states. A *state* is triggered by passing it a single
+ input (or 'trigger') event and once executed each state
+ then emits an output event. For each *state* the logic
+ for the *state* is embedded in one or more *tasks*. Each
+ *task* contains specific *task logic* that is executed by
+ the APEX execution environment each time the *task* is
+ invoked. Where there is more than one *task* in a *state*
+ then the *state* also defines some *task selection logic*
+ to select an appropriate task each time the *state* is
+ executed.
+
+ .. container:: paragraph
+
+ Therefore, to create a new policy we must first define
+ one or more tasks.
+
+ .. container:: paragraph
+
+ To create a new Task click on the 'Tasks' tab. In the

+
+ .. container:: imageblock
+
+ .. container:: content
+
+ |Right click to create a new task|
+

+
+ Tasks are configured with a set of *input fields* and a

+ for a task use the 'Add Task Input Field' and 'Add Task
+ Output Field' button. The list of input and out fields to
+ add for the ``MorningBoozeCheck`` task are given below.
+ The input fields are drawn from the parameters in the
+ state’s input event, and the task’s output fields are
+ used to populate the state’s output event. The task’s
+ input and output fields must be a subset of the event
+ parameters defined for the input and output events for
+ any state that uses that task. (You may have noticed that
+ the input and output fields for the ``MorningBoozeCheck``
+ task have the exact same names and reuse the item schemas
+ that we used for the parameters in the ``SALE_INPUT`` and
+ ``SALE_AUTH`` events respectively).

+
+ Each task must include some 'Task Logic' that implements
+ the behaviour for the task. Task logic can be defined in
+ a number of different ways using a choice of languages.
+ For this task we will author the logic using the
+ Java-like scripting language called
+ ```MVEL`` <https://en.wikipedia.org/wiki/MVEL>`__.
+
+ .. container:: paragraph
+
+ For simplicity use the following code for the task logic.
+ Paste the script text into the 'Task Logic' box, and use
+ "MVEL" as the 'Task Logic Type / Flavour'.
+
+ .. container:: paragraph
+
+ This logic assumes that all items with ``item_ID``
+ between 1000 and 2000 contain alcohol, which is not very
+ realistic, but we will see a better approach for this
+ later. It also uses the standard ``Java`` time utilities
+ to check if the current time is between ``00:00:00 GMT``
+ and ``11:30:00 GMT``. For a detailed guide to how to
+ write your own logic in
+ ```JavaScript`` <https://en.wikipedia.org/wiki/JavaScript>`__,
+ ```MVEL`` <https://en.wikipedia.org/wiki/MVEL>`__ or one
+ of the other supported languages please refer to APEX
+ Programmers Guide.

+
+ Each policy must define a 'First State' and a 'Policy
+ Trigger Event'. The 'Policy Trigger Event' is the input
+ event for the policy as a whole. This event is then
+ passed to the first state in the chain of states in the
+ policy, therefore the 'Policy Trigger Event' will be the
+ input event for the first state. Each policy can only
+ have one 'First State'. For our ``MyFirstPolicy`` policy,
+ select ``BoozeAuthDecide`` as the 'First State'. This
+ will automatically select ``SALE_INPUT`` as the 'Policy
+ Trigger Event' for our policy.
+

+ as the 'Local Name' for the task.
+
+ .. container:: paragraph
+
+ in the case where a state references more than one task,
+ a 'Default Task' must be selected for the state and some
+ logic ('Task Selection Logic') must be specified to

+ new state ``BoozeAuthDecide`` only has one task the
+ default task is automatically selected and no 'Task
+ Selection Logic' is required.
+
+ .. container:: admonitionblock note
+
+ .. NOTE::
+
+ .. container:: paragraph
+ In a 'Policy' 'State' a 'State Output Mapping' has 3 roles: 1) Select which 'State'
+ should be executed next, 2) Select the type of the state’s 'Outgoing Event', and
+ 3) Populate the state’s 'Outgoing Event'. This is how states are chained together
+ to form a (`Directed Acyclic Graph (DAG) <https://en.wikipedia.org/wiki/Directed_acyclic_graph>`__)
+ of states. The final state(s) of a policy are those that do not select any 'next'
+ state. Since a 'State' can only accept a single type of event, the type of the
+ event emitted by a previous 'State' must match the incoming event type of the next
+ 'State'. This is also how the last state(s) in a policy can emit events of
+ different types. The 'State Output Mapping' is also responsible for taking the
+ fields that are output by the task executed in the state and populating the
+ state’s output populating the state’s output event before it is emitted.
+
+ Each 'Task' referenced in 'State' must have a defined 'Output Mapping' to take the output of the task, select an 'Outgoing Event' type for the state, populate the state's outgoing event, and then select the next state to be executed (if any).
+
+ There are 2 basic types of output mappings:
+
+ .. container:: olist arabic
+
+ #. **Direct Output Mappings** have a single value for 'Next State' and a single value for 'State Output Event'. The outgoing event for the state is automatically created, any outgoing event parameters that were present in the incoming event are copied into the outgoing event, then any task output fields that have the same name and type as parameters in the outgoing event are automatically copied into the outgoing event.
+ #. **Logic-Based State Output Mappings / Finalizers** have some logic defined that dynamically selects and creates the 'State Outgoing Event', manages the population of the outgoing event parameters (perhaps changing or adding to the outputs from the task), and then dynamically selects the next state to be executed (if any).
+
+ .. container:: paragraph
+
+ Each task reference must also have an associated 'Output
+ State Mapping' so we need an 'Output State Mapping' for
+ the ``BoozeAuthDecide`` state to use when the
+ ``MorningBoozeCheck`` task is executed. The simplest type
+ of output mapping is a 'Direct Output Mapping'.
+
+ .. container:: paragraph
+
+ Create a new 'Direct Output Mapping' for the state called
+ ``MorningBoozeCheck_Output_Direct`` using the 'Add New
+ Direct State Output Mapping' button. Select ``SALE_AUTH``
+ as the output event and select ``None`` for the next
+ state value. We can then select this output mapping for
+ use when the the ``MorningBoozeCheck`` task is executed.
+ Since there is only state, and only one task for that
+ state, this output mapping ensures that the
+ ``BoozeAuthDecide`` state is the only state executed and
+ the state (and the policy) can only emit events of type
+ ``SALE_AUTH``. (You may remember that the output fields
+ for the ``MorningBoozeCheck`` task have the exact same
+ names and reuse the item schemas that we used for the
+ parameters in ``SALE_AUTH`` event. The
+ ``MorningBoozeCheck_Output_Direct`` direct output mapping
+ can now automatically copy the values from the
+ ``MorningBoozeCheck`` task directly into outgoing
+ ``SALE_AUTH`` events.)

+ This task also requires some 'Task Logic' to implement

+
+ .. container:: paragraph
+
+ For simplicity use the following code for the task logic.
+ It again assumes that all items with ``item_ID`` between
+ 1000 and 2000 contain alcohol. We again use the standard
+ ``Java`` time utilities to check if the current time is
+ between ``00:00:00 CET`` and ``13:00:00 CET`` or if it is
+ ``Sunday``.
+
+ .. container:: paragraph
+
+ For this task we will again author the logic using the
+ ```MVEL`` <https://en.wikipedia.org/wiki/MVEL>`__
+ scripting language. Sample task logic code (specified in
+ ```MVEL`` <https://en.wikipedia.org/wiki/MVEL>`__) is
+ given below. For a detailed guide to how to write your
+ own logic in
+ ```JavaScript`` <https://en.wikipedia.org/wiki/JavaScript>`__,

+ ``BoozeAuthDecide`` use the 'Add new task' button. Select
+ our new ``MorningBoozeCheckAlt1`` task, and use the name
+ of the task as the 'Local Name' for the task. The
+ ``MorningBoozeCheckAlt1`` task can reuse the same
+ ``MorningBoozeCheck_Output_Direct`` 'Direct State Output
+ Mapping' that we used for the ``MorningBoozeCheck`` task.
+ (Recall that the role of the 'State Output Mapping' is to
+ select the output event for the state, and select the
+ next state to be executed. These both remain the same as
+ before.)
+
+ .. container:: paragraph
+
+ Since our state has more than one task we must define
+ some logic to determine which task should be used each
+ time the state is executed. This *task selection logic*
+ is defined in the state definition. For our
+ ``BoozeAuthDecide`` state we want the choice of which
+ task to use to be based on the ``branch_ID`` from which
+ the ``SALE_INPUT`` event originated. For simplicity sake
+ let us assume that branches with ``branch_ID`` between
+ ``0`` and ``999`` should use the ``MorningBoozeCheck``
+ task, and the branches with with ``branch_ID`` between
+ ``1000`` and ``1999`` should use the

+ (specified in
+ ```JavaScript`` <https://en.wikipedia.org/wiki/JavaScript>`__)
+ is given below. Paste the script text into the 'Task
+ Selection Logic' box, and use "JAVASCRIPT" as the 'Task
+ Selection Logic Type / Flavour'. It is necessary to mark
+ one of the tasks as the 'Default Task' so that the task
+ selection logic always has a fallback default option in
+ cases where a particular task cannot be selected. In this
+ case the ``MorningBoozeCheck`` task can be the default
+ task.

+Introduction
+^^^^^^^^^^^^
+
+ .. container:: sectionbody
+
+ .. container:: paragraph
+
+ This module contains several demos for
+ Policy-controlled Video Streaming (PCVS). Each demo

+ scripting languages for the policy logic). To run the
+ demo, a vanilla Ubuntu server with some extra software
+ packages is required:
+
+ .. container:: ulist
+
+ - Mininet as network simulator
+
+ - Floodlight as SDN controller
+
+ - Kafka as messaging system
+
+ - Zookeeper for Kafka configuration
+
+ - APEX for policy control

+VPN SLA Demo
+^^^^^^^^^^^^^
+
+ .. container:: sect1
+
+ .. container:: sectionbody
+
+ .. container:: paragraph
+
+ This demo uses a network with several central office
+ and core switches, over which two VPNs are run. A
+ customer ``A`` has two location ``A1`` and ``A2`` and
+ a VPN between them. A customer ``B`` has two location
+ ``B1`` and ``B2`` and a VPN between them.
+
+ .. container:: imageblock
+

+
+ |VPN SLA Architecture|
+
+ .. container:: paragraph
+
+ The architecture above shows the scenario. The
+ components are realized in this demo as follows:
+
+ .. container:: ulist
+
+ - *CEP / Analytics* - a simple Python script taking
+ events from Kafka and sending them to APEX
+
+ - *APEX / Policy* - the APEX engine running the VPA
+ SLA policy
+
+ - *Controller* - A vanilla Floodlight controller
+ taking events from the Link Monitor and configuring
+ Mininet
+
+ - *Network* - A network created using Mininet
+
+ .. container:: paragraph
+
+ The demo requires to start some software (detailed
+ below). To show actual video streams, we use ``VLC``.
+ If you do not want to show video streams, but only the
+ policy, skip the ``VLC`` section.
+
+ .. container:: paragraph
+
+ All shown scripts are available in a full APEX
+ installation in
+ ``$APEX_HOME/examples/scripts/pcvs/vpnsla``.

+
+ .. container:: paragraph
+
+ In a new Xterm start the Link Monitor. The Link
+ Monitor has a 30 second sleep to slow down the
+ demonstration. So the first action of it comes 30
+ seconds after start. Every new action in 30 second
+ intervals.
+

+
+ sudo -i
+ . ./env.sh
+ cd $src_dir
+ xterm -hold -e 'python3 $src_dir/kafka-python/LinkMonitor.py' &
+
+ .. container:: paragraph
+
+ Now all software should be started and the demo is
+ running. The Link Monitor will send link up events,
+ picked up by APEX which triggers the policy. Since
+ there is no problem, the policy will do nothing.

+ In the Mininet console, type ``xterm A1 A2`` and

+
+ .. container:: paragraph
+
+ ``A2`` and ``B2`` are the receiving nodes. In these
+ terminals, run ``vlc-wrapper``. In each opened VLC
+ window do
+
+ .. container:: ulist
+
+ - Click Media → Open Network Stream
+

+
+ .. container:: paragraph
+
+ ``A1`` and ``B1`` are the sending nodes (sending
+ the video stream) In these terminals, run
+ ``vlc-wrapper``. In each opened VLC window do
+
+ .. container:: ulist
+
+ - Click Media → Stream
+
+ - Add the video (from ``/usr/local/src/videos``)
+
+ - Click ``Stream``
+
+ - Click ``Next``
+
+ - Change the destination
+ ``RTP / MPEG Transport Stream`` and click
+ ``Add``
+
+ - Change the address and type to ``10.0.0.2`` in
+ ``A1`` and to ``10.0.0.4`` in ``B1``
+
+ - Turn off ``Active Transcoding`` (this is
+ important to minimize CPU load)
+
+ - Click ``Next``
+
+ - Click ``Stream``
+
+ .. container:: paragraph
+
+ The video should be streaming across the network
+ from ``A1`` to ``A2`` and from ``B1`` to ``B2``. If
+ the video streams a slow or interrupted the CPU
+ load is too high. In these cases either try a
+ better machine or use a different (lower quality)
+ video stream.

+ :name: take_out_l09_and_let_the_policy_do_it_s_magic
+
+ .. container:: paragraph
+
+ Now it is time to take out the link ``L09``. This
+ will be picked up by the Link Monitor, which sends
+ a new event (L09 DOWN) to the policy. The policy
+ then will calculate which customer should be
+ impeded (throttled). This will continue, until SLAs
+ are violated, then a priority calculation will kick
+ in (Customer ``A`` is prioritized in the setup).
+
+ .. container:: paragraph
+
+ To initiate this, simply type ``link s5 s6 down``
+ in the Mininet console followed by ``exit``.
+
+ .. container:: paragraph
+
+ If you have the video streams running, you will see
+ one or the other struggeling, depending on the
+ policy decision.

+
+VPN SLA Policy
+^^^^^^^^^^^^^^
+
+ .. container:: sectionbody
+
+ .. container:: paragraph
+
+ The VPN SLA policy is designed as a MEDA policy. The
+ first state (M = Match) takes the trigger event (a
+ link up or down) and checks if this is a change to the
+ known topology. The second state (E = Establish) takes
+ all available information (trigger event, local
+ context) and defines what situation we have. The third
+ state (D = Decide) takes the situation and selects
+ which algorithm is best to process it. This state can
+ select between ``none`` (nothing to do), ``solved`` (a
+ problem is solved now), ``sla`` (compare the current
+ customer SLA situation and select one to impede), and
+ ``priority`` (impede non-priority customers). The
+ fourth and final state (A = Act) selects the right
+ action for the taken decision and creates the response
+ event sent to the orchestrator.
+
+ .. container:: paragraph
+
+ We have added three more policies to set the local
+ context: one for adding nodes, one for adding edges
+ (links), and one for adding customers. These policies
+ do not realize any action, they are only here for
+ updating the local context. This mechanism is the
+ fasted way to update local context, and it is
+ independent of any context plugin.
+
+ .. container:: paragraph
+
+ The policy uses data defined in Avro, so we have a
+ number of Avro schema definitions.
+
+Context Schemas
+---------------
+
+ .. container:: sect1
+
+ .. container:: sectionbody
+
+ .. container:: paragraph
+
+ The context schemas are for the local context. We
+ model edges and nodes for the topology, customers, and
+ problems with all information on detected problems.

+ "doc": "Links used by this customer",

+ }
+ ]
+ }
+
+
+Trigger Schemas
+---------------
+
+ .. container:: sect1
+
+ .. container:: sectionbody
+
+ .. container:: paragraph
+
+ The trigger event provides a status as ``UP`` or
+ ``DOWN``. To avoid tests for these strings in the
+ logic, we defined an Avro schema for an enumeration.
+ This does not impact the trigger system (it can still
+ send the strings), but makes the task logic simpler.

+
+ .. code:: CodeRay
+
+ {
+ "type": "enum",
+ "name": "Status",
+ "symbols" : [
+ "UP",
+ "DOWN"
+ ]
+ }
+
+Context Logic Nodes
+--------------------
+
+ .. container:: sect1
+
+ .. container:: sectionbody
+
+ .. container:: paragraph
+
+ The node context logic simply takes the trigger event
+ (for context) and creates a new node in the local
+ context topology.

+ .. container:: paragraph
+
+ This is the logic for the establish state. It is the
+ most complicated logic, since establishing a situation
+ for a decision is the most important part of any
+ policy. First, the policy describes what we find (the
+ switch block), in terms of 8 normal situations and 1
+ extreme error case.
+
+ .. container:: paragraph
+
+ If required, it creates local context information for
+ the problem (if it is new) or updates it (if the
+ problem still exists). It also calculates customer SLA
+ downtime and checks for any SLA violations. Finally,
+ it creates a situation object.

+ :depth: 3
+
+Sample APEX Policy in TOSCA format
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ .. container:: paragraph
+
+ An example APEX policy in TOSCA format for the vCPE
+ use case can be found here:
+
+ .. container:: ulist
+
+ - `APEX TOSCA Policy
+ vCPE <https://github.com/onap/policy-models/blob/master/models-examples/src/main/resources/policies/vCPE.apex.policy.operational.input.tosca.json>`__
+
+My First Policy
+^^^^^^^^^^^^^^^
+
+ .. container:: paragraph
+
+ A good starting point is the ``My First Policy`` example. It
+ describes a sales problem, to which policy can be applied.
+ The example details the policy background, shows how to use
+ the REST Editor to create a policy, and provides details for
+ running the policies. The documentation can be found:
+
+ .. container:: ulist
+
+ - :ref:`My-First-Policy on the APEX site <apex-myFirstExample>`
+
+VPN SLA
+^^^^^^^
+
+ .. container:: paragraph
+
+ The domain Policy-controlled Video Streaming (PCVS) contains
+ a policy for controlling video streams with different
+ strategies. It also provides details for installing an
+ actual testbed with off-the-shelve software (Mininet,
+ Floodlight, Kafka, Zookeeper). The policy model here
+ demonstrates virtually all APEX features: local context and
+ policies controlling it, task selection logic and multiple
+ tasks in a single state, AVRO schemas for context, AVOR
+ schemas for events (trigger and local), and a CLI editor
+ specification of the policy. The documentation can be found:
+
+ .. container:: ulist
+
+ - :ref:`VPN SLA Policy on the APEX site <apex-PCVSExample>`
+
+Decision Maker
+^^^^^^^^^^^^^^
+
+ .. container:: paragraph
+
+ The domain Decision Maker shows a very simple policy for
+ decisions. Interesting here is that the it creates a Docker
+ image to run the policy and that it uses the APEX REST
+ applications to update the policy on the-fly. It also has
+ local context to remember past decisions, and shows how to
+ use that to no make the same decision twice in a row. The
+ documentation can be found:

+
+ The *taskParameters* field is specified under *engineParameters*

+ If the taskId is not specified, then the parameters are added to all tasks.

+Configure Task Parameters
+#########################
+

+ "taskId": "Task_Act0",
+ "key": "ParameterKey2",
+ "value": "ParameterValue2"
+ }
+ ]
+ }
+ }
+
+ .. container:: paragraph
+
+ TaskParameters can be used to pass parameters from ApexConfig
+ to the policy logic. In the config, these are optional.
+ The list of task parameters provided in the config may be added
+ to the tasks or existing task parameters in the task will be overriden.
+
+ .. container:: paragraph
+
+ If taskId is provided in ApexConfig for an entry, then that
+ parameter is updated only for that particular task. Otherwise,
+ the task parameter is added to all tasks.

API Swagger
Also, in the POST payload passed into each policy or policy type creation call (i.e. POST API invocation), the client needs to explicitly
specify the version of the policy or policy type to create. That being said, the "version" field is mandatory in the TOSCA service template
-formatted policy or policy type payload. Likewise in the legacy guard and the operational policy payload, "policy-version" is mandatory too.
-If the version is missing, that POST call will return "406 - Not Acceptable" and the policy or policy type to create will not be stored in

+formatted policy or policy type payload. If the version is missing, that POST call will return "406 - Not Acceptable" and
+the policy or policy type to create will not be stored in the database.
To avoid inconsistent versions between the database and policies deployed in the PDPs, policy API REST service employs some enforcement
rules that validate the version specified in the POST payload when a new version is to create or an existing version to update.
of the version and feed an informative warning back to the client if the specified version is not good.
To be specific, the following rules are implemented to enforce the version:
-1. If the version is not in the database, we simply insert it. For example: if policy version 1.0.0 is stored in the database and now
+1. If the incoming version is not in the database, we simply insert it. For example: if policy version 1.0.0 is stored in the database and now
a client wants to create the same policy with updated version 3.0.0, this POST call will succeed and return "200" to the client.
-2. If the version is already in the database, "406 - Not Acceptable" will be returned along with the message saying "specified version x.x.x"
- is already existing and the latest version is y.y.y. It can force the client to create a newer version than the latest one.
- For example, if policy versions "1.0.0" and "2.0.0" are already in the database and a client wants to create version "1.0.0" again, the
- client will get "406" code returned along with the message "specified version 1.0.0 is already existing and the latest version is 2.0.0".
- Then the client can change the version to anything newer than "2.0.0", such as "3.0.0".
+2. If the incoming version is already in the database and the incoming payload is different from the same version in the database,
+ "406 - Not Acceptable" will be returned. This forces the client to update the version of the policy if the policy is changed.
+
+3. If a client creates a version of a policy and wishes to update a property on the policy, they must delete that version of the policy and re-create it.
-3. If multiple policies or policy types are included in the POST payload, policy API will also check if duplicate version exists in between
+4. If multiple policies are included in the POST payload, policy API will also check if duplicate version exists in between
any two policies or policy types provided in the payload. For example, a client provides a POST payload which includes two policies with the same
name and version but different policy properties. This POST call will fail and return "406" error back to the calling application along with a
message such as "duplicate policy {name}:{version} found in the payload".
-4. The same version validation is applied to legacy types of policies and policy types too (i.e. legacy guard and operational) so that everything
- is consistent.
+5. The same version validation is applied to policy types too.
-5. To avoid unnecessary id/version inconsistency between the ones specified in the entity fields and the ones returned in the metadata field,
+6. To avoid unnecessary id/version inconsistency between the ones specified in the entity fields and the ones returned in the metadata field,
"policy-id" and "policy-version" in the metadata will only be set by policy API. Any incoming explicit specification in the POST payload will be
ignored. For example, A POST payload has a policy with name "sample-policy-name1" and version "1.0.0" specified. In this policy, the metadata
also includes "policy-id": "sample-policy-name2" and "policy-version": "2.0.0". The 200 return of this POST call will have this created policy with
metadata including "policy-id": "sample-policy-name1" and "policy-version": "1.0.0".
-.. swaggerv2doc:: swagger/guard-policy-api.json
-
-It is worth noting that guard policy name should start with one of the three: *guard.frequency.*, *guard.minmax.*, or *guard.blacklist.*.
-Otherwise, it will complain that guard policy type cannot be found (does not exist). Apart from policy name, the policy version specified
-in API path should be an integer, e.g. 1, 2, 10, instead of "1.0.0", "2.0.1", etc.
-These naming restrictions will disappear after we evolve to use well-formed TOSCA Service Template for guard policies and
-legacy policy design API is then deprecated.
-
.. swaggerv2doc:: swagger/operational-policy-api.json
-Likewise, the policy version specified in operational policy API path should be an integer too, e.g. 1, 2, 10, instead of
-"1.0.0", "2.0.1", etc. This restriction will disappear after we deprecate legacy policy design API in the near future release.

-Regarding DELETE APIs for both TOSCA policies and legacy policies, we only expose API to delete one particular version of policy
+Regarding DELETE APIs for TOSCA compliant policies, we only expose API to delete one particular version of policy
or policy type at a time for safety purpose. If client has the need to delete multiple or a group of policies or policy types,
-they will need to delete one by one.

supports development, deployment, and execution of any type of policy in ONAP. The Policy Framework is metadata (model)

+development ways of working such as `DevOps
+<https://en.wikipedia.org/wiki/DevOps>`__. A metadata driven approach also allows the amount of programmed support
required for policies to be reduced or ideally eliminated.
We have identified five capabilities as being essential for the framework:
approach for policies, see the :ref:`TOSCA Policy Primer <tosca-label>` for more information on how policies are modeled
in TOSCA.
-1. A Policy Type is a general implementation of a policy for a feature. For example, a Policy Type could be written to
- manage Service Level Agreements for VPNs. The Policy Type is designed by a domain expert, who specifies the
- parameters, triggers, and actions that the Policy Type will have. The implementation (the logic, rules, and tasks of
- the Policy Type) is implemented by a skilled policy developer in consultation with domain experts.
+ 1. A *Policy Type* describes the properties, targets, and triggers that the policy for a feature can have. A Policy type is
+ implementation independent. It is the metadata that specifies:
- a. For example, the VPN Policy Type is used to create VPN policies for a bank network, a car dealership network, or a
- university with many campuses.
+ - the *configuration* data that the policy can take. The Policy Type describes each property that a policy of a
+ given type can take. A Policy Type definition also allows the default value, optionality, and the ranges of properties
+ to be defined.
- b. In ONAP, specific ONAP Policy Types are used to create specific policies that drive the ONAP Platform and
- Components.
+ - the *targets* such as network element types, functions, services, or resources on which a policy of the given type
+ can act.
-2. A Policy is created by configuring a Policy Type with parameters. For example, the SLA values in the car dealership
- VPN policy for a particular dealership are configured with values appropriate for the expected level of activity in
- that dealership.
+ - the *triggers* such as the event type, filtered event, scheduled trigger, or conditions that can activate a policy
+ of the given type.
+ Policy Types are hierarchical, A Policy Type can inherit from a parent Policy Type, inheriting the properties, targets,
+ and triggers of its parent. Policy Types are developed by domain experts in consultation with the developers that
+ implement the logic and rules for the Policy Type.
+
+ 2. A *Policy* is defined using a Policy Type. The Policy defines:
+
+ - the values for each property of the policy type
+ - the specific targets (network elements, functions, services, resources) on which this policy will act
+ - the specific triggers that trigger this policy.
+
+ 3. A *Policy Type Implementation* or *Raw Policy*, is the logic that implements the policy. It is implemented by a
+ skilled policy developer in consultation with domain experts. The implementation has software that reads the Policy
+ Type and parses the incoming configuration properties. The software has domain logic that is triggered when one of the
+ triggers described in the Policy Type occurs. The software logic executes and acts on the targets specified in the
+ Policy Type.
+
+
+For example, a Policy Type could be written to describe how to manage Service Level Agreements for VPNs. The VPN Policy
+Type can be used to create VPN policies for a bank network, a car dealership network, or a university with many campuses.
+The Policy Type has two parameters:
+
+ - The *maximumDowntime* parameter allows the maximum downtime allowed per year to be specified
+ - The *mitigationStrategy* parameter allows one of three strategies to be selected for downtime breaches
+
+ - *allocateMoreResources*, which will automatically allocate more resources to mitigate the problem
+ - *report*, which report the downtime breach to a trouble ticketing system
+ - *ignore*, which logs the breach and takes no further action
+
+The Policy Type defines a trigger event, an event that is received from an analytics system when the maximum downtime
+value for a VPN is breached. The target of the policy type is an instance of the VPN service.
+
+The Policy Type Implementation is developed that can configure the maximum downtime parameter in an analytics system,
+can receive a trigger from the analytics system when the maximum downtime is breached, and that can either request more
+resources, report an issue to a trouble ticketing system, and can log a breach.
+
+VPN Policies are created by specifying values for the properties, triggers, and targets specifed in VPN Policy Type.
+
+In the case of the bank network, the *maximumDowntime* threshold is specified as 5 minutes downtime per year and the
+*mitigationStrategy* is defined as *allocateMoreResources*, and the target is specified as being the bank's VPN service
+ID. When a breach is detected by the analytics system, the policy is executed, the target is identified as being the
+bank's network, and more resources are allocated by the policy.
+
+For the car dealership VPN policy, a less stringent downtime threshold of 60 minutes per year is specified, and the
+mitigation strategy is to issue a trouble ticket. The university network is best effort, so a downtime of 4 days per
+year is specified. Breaches are logged and mitigated as routine network administration tasks.
+
+In ONAP, specific ONAP Policy Types are used to create specific policies that drive the ONAP Platform and Components.

all the PDPs of the same type that are running the same policies together for deployment.

2.2 Policy Design Architecture
------------------------------
Policies that are expressed via natural language or a model require some development work ahead of time for them to be
translated into concrete runtime policies. Some Policy Domains will be set up and available in the platform during
startup such as Control Loop Operational Policy Models, OOF placement Models, DCAE microservice models. Policy type

policy for a particular domain use case. The policy type implementation specifies the model information, rules, and
tasks that a policy type requires to generate concrete policies.
-All policy types must implement the ONAP Policy Framework *PolicyType* interface. This interface allows
-*PolicyDevelopment* to manage policy types and to generate policies from these policy types in a uniform way regardless
-of the domain that the policy type is addressing or the PDP technology that will execute the policy. The interface is
-used by *PolicyDevelopment* to determine the PDP technology of the policy type, the structure, type, and definition of
-the model information that must be supplied to the policy type to generate a concrete policy.
+All policy types are specified in a TOSCA service template. Once policy types are defined and created in the system,
+*PolicyDevelopment* manages them and uses them to allow policies to be created from these policy types in a uniform
+way regardless of the domain that the policy type is addressing or the PDP technology that will execute the policy.
-A *PolicyTypeImpl* is developed for a certain type of PDP (for example XACML oriented for decision policies or Drools
-rules oriented for ECA policies). The design environment and tool chain for a policy type is specific for the type of
-policy being designed.

+a policy type implementation is specific to the technology of the PDP on which policies that use that policy type
+implementation will use.
-The *PolicyTypeImpl* implementation (or raw policy) is the specification of the specific rules or tasks, the flow of
-the policy, its internal states and data structures and other relevant information. A *PolicyTypeImpl* is specific to a
-PDP technology, that is XACML, Drools, or APEX. *A PolicyTypeImpl* can be specific to a particular policy type, it can

-captures the generic logic required to manage the faults and specifies the vendor specific information that must be

-equipment is created by setting the parameters specified in the policy type together with the specific modeled
-information, rules and tasks in the policy type implementation for that vendor model of vCPE.

+This section will cover how to interact with the PDP-D using telemetry commands. This assumes that you have a PDP-D running to interact with. Take a look at the page "Methods to run PDP-D" if you do not have a PDP-D running for testing purposes.
+
Telemetry
^^^^^^^^^
The username and password for the Telemetry commands are in *${POLICY_HOME}/config/engine.properties*.
+If you are using Eclipse, the credentials can be found in the file **install-drools/src/files/base.conf** within the "drools-pdp" repository.
+The environment variables $TELEMETRY_USER and $TELEMETRY_PASSWORD will also have the credentials if they have already been set.
+
+Recall you can use the command "docker exec -it drools bash" to get the PDP-D running with Docker.
+
+ .. code-block:: bash
+
+ docker exec -it drools bash
+
+Your terminal should now look similar to "policy@drools:/<path>". This indicates you are in the drools docker container. If you run "policy status" the controller should be running.
+
+ .. image:: img/docker/policyStatus.png
+
+To enter the telemetry subshell, use the command "telemetry".
+
+ .. code-block:: bash
+
+ telemetry
+
+Use the "exit" command to exit the telemetry subshell. The terminal will now go back to the docker container.
+
+ .. code-block:: bash
+
+ exit
+
+ .. image:: img/docker/credentials.png
Injecting messages:
-------------------
-To inject messages use the following command. The injected message will look as if it came in from the specified topic and will be processed accordingly.
+To inject messages, use the following command. The injected message will look as if it came in from the specified topic and will be processed accordingly.
Use the command:
http --verify=no --default-scheme=https -a <userName>:<password> PUT :9696/policy/pdp/engine/topics/sources/<comm>/<topic>/events @<onsetFile> Content-Type:"text/plain"
-where <comm> is either "dmaap", "ueb", or "noop", depending on how the topic has been defined in the
-configuration. "dmaap" is the default deployed messaging communication infrastructure in an ONAP installation.
-The following is the equivalent "curl" version:
+The equivalent "curl" version:
.. code-block:: bash
curl --insecure --silent --user <userName>:<password> -X PUT --header "Content-Type: text/plain" --data @<onsetFile> https://localhost:9696/policy/pdp/engine/topics/sources/<comm>/<topic>/events
-The topic being used is *unauthenticated.DCAE_CL_OUTPUT*, which is subject to change. The onset file is a file that contains the data to inject as the onset. The data contained depends on the use case. This is an example for VoLTE:
+Note: you may have to replace "https" with "http" depending on how you are running the drools-pdp.
+
+The <comm> is a messaging communication infrastructure in an ONAP installation. Depending on how a topic has been defined in the configuration, the <comm> is either "dmaap", "ueb", or "noop".
+The default messaging communication infrastructure is "dmaap".
+
+The <topic> is a specific topic name used to send and/or receive information. There are two types of topics:
+
+1. **source** topics (Example: dmaap.source.topics=APPC-LCM-WRITE or dmaap.source.topics=APPC-CL)
+
+2. **sink** topics (Example: dmaap.sink.topics=APPC-LCM-READ or dmaap.sink.topics=APPC-CL)
+
+You can extract <comm> and <topic> from the following example:
+Example: dmaap.sink.topics=APPC-LCM-READ
+
+1. <comm>=dmaap
+
+2. <topic>=APPC-LCM-READ
+
+The onset is a json file that contains the data to inject as the onset. The data contained depends on the use case. This is an example for the vFirewall usecase:

Simulators
^^^^^^^^^^
-Currently, there are 4 supported simulators: A&AI, SO, vFC, and guard. When they are up, they are accessed via localhost on the following ports: A&AI – 6666, SO – 6667, vFC – 6668, and guard – 6669. They all respond with hard-coded values representing their various success messages except for with certain inputs. For the A&AI simulator, if the value being queried with a “GET” query is “getFail” the simulator returns an exception message, if the value being queried in a “GET” query is “disableClosedLoop” the simulator returns a response with the value of “is-closed-loop-disabled” set to true, and if the value being queried in a named query is “error” the response from the simulator is A&AI’s failure message. The other simulator that can return multiple response is the guard simulator, and that returns a deny response if the closed loop control name passed in is “denyGuard”

+To check the status of the simulators, run the command: "*policy status*". If the feature "controlloop-utils" is enabled, the simulators are being used, otherwise, they are not.
**Turning on the simulators**
- First, make sure the controller is off by running the command “*policy stop*”.
- Then turn the feature off with the command “*features disable controlloop-utils*”.
- - Finally restart the controller by running “*policy start*”.
+ - Finally restart the controller by running “*policy start*”.
- Run “*features status*” again and the *feature controlloop-utils* will be **disabled**.
**For Junits**
- For Junits, the package *org.onap.policy.simulators* is neeeded. In the Util class, there are four methods to start the four different simulators: *buildAaiSim()*, *buildSoSim()*, *buildVfcSim()*, and *buildGuardSim()*. Once the method is called, the simulator should be up and waiting to respond to requests. To bring down the simulators, call *HttpServletServer.factory.destroy()*.

+This guide will help configure and test the guard connection from PDP-D (drools-pdp) to PDP-X (xacml-pdp). This guide assumes that the PDP-D is installed and running policy properly with other properties being set properly.
Configuration
-^^^^^^^^^^^^^
+^^^^^^^^^^^^^
Prerequisites
-------------
Stop Policy, open, and verify the config:
-- Stop policy with *policy stop*
+- Stop policy with **policy stop**
- Open *$POLICY_HOME/config/controlloop.properties.environment*
- Make sure the *sql.db.host*, *sql.db.username* and *sql.db.password* are set correctly
**guard.disabled** - For enabling / disabling guard functionality.
- For example, to enable set it to false.
- - When this is set to true, the previous two properties will be ignored.
+ - When this is set to true, the previous two properties (guard.url and guard.jdbc.url) will be ignored.
- If guard is enabled, then the following PDP-X properties must also be set.
**pdpx.client.password** - Client password
-
Verification
-^^^^^^^^^^^^
+^^^^^^^^^^^^
It is recommended to test using CLI tools before running since changing bash command parameters are faster than restarting policy.
Logs Verification
-----------------
-Checking the logs is straight forward. Check the *$POLICY_HOME/logs/error.log* file for the word "*callRESTfulPDP*" for any exceptions thrown. If they are thrown then there was a problem with the connection.
-You can also check the *$POLICY_HOME/logs/network.log* file for the word "*Indeterminate*" which implies the connection failed or got a non 200 response code.

+
CLI Verification
----------------
It can be helpful to test the PDP-X connection using bash commands to make sure that the PDP-X properties are correct and the guard.url property is correct before running policy.
**Method 1: httpie - CLI, cURL-like tool for humans**
-
+
Using the http command we can make a request directly to PDP-X from the command line. Use the following form:
.. code-block:: bash
-
+
http
POST pdp:8081/pdp/api/getDecision
Authorization:<yourAuth> ClientAuth:<yourClientAuth>
Environment:<environment> Content-Type:application/json < guard_request.json
-
+
| where:
| *<yourAuth>* is the string generated from user:pass converted to base64 encoding
| (a conversion tool is available at https://www.base64encode.org/)
| *<yourClientAuth>* is generated the same way but from the client user and pass.
| *<environment>* is the context of the request. For example: TEST
| *pdp* is the host of the PDP-X
-
+
The guard_request.json should be in the form of the following:
-
+
.. code-block:: json
:caption: guard_request.json
-
+
{
"decisionAttributes": {
"actor": "APPC",
curl --silent -k -u "<userName>:<password>" --header "X-FromAppId: <fromApp>" --header "Content-Type: application/json" --header "Accept: application/json" --header "X-TransactionId: <requestID>" -X GET https://aai.api.simpledemo.openecomp.org:8443/aai/v11/cloud-infrastructure/cloud-regions | python -m json.tool
- Take note of all the cloud-owner/cloud-region combinations. In this example, there are 3 combinations: Skynet/CL-MR1, AMIST/AMCR1, and Rackspace/DFW.

+Methods to run PDP-D
+**********************************************************
+
+.. contents::
+ :depth: 2
+
+There are two methods you can use to run a PDP-D for testing purposes:
+
+1. Using Docker
+
+2. Using Eclipse
+
+Using Docker
+^^^^^^^^^^^^
+**Step 1:** Clone the integration/csit repository.
+
+You can find the repo here: https://gerrit.onap.org/r/admin/repos/integration/csit.
+Although this repository is used for CSIT testing, we can use this as a means to get a PDP-D up and running with docker.
+
+ .. code-block:: bash
+
+ git clone "https://gerrit.onap.org/r/integration/csit"
+
+**Step 2:** Note the "docker-compose" commands that will be used.
+
+ .. code-block:: bash
+
+ docker-compose -f ${WORKSPACE}/scripts/policy/docker-compose-drools-apps.yml up -d
+
+ docker-compose -f ${WORKSPACE}/scripts/policy/docker-compose-drools-apps.yml down -v
+
+Note that ${WORKSPACE} refers to the local path where the csit repository is.
+
+**Step 3:** Edit the "docker-compose-drools-apps.yml" file.
+
+Take a look at the "csit/scripts/policy/docker-compose-drools-apps.yml" file. It should look similar to this:
+
+ .. image:: img/docker/yamlClone.png
+
+The following changes need to be made based on which version you are running and your local setup.
+
+ .. code-block:: bash
+
+ ${POLICY_MARIADB_VER} should be "10.2.14" (without quotes, version subject to change)
+
+ ${WORKSPACE} should be the absolute path to the cloned "csit" repository.
+
+ ${POLICY_DROOLS_APPS_VERSION} should be "1.6.0" (without quotes, version subject to change).
+
+If you are using MacOS, you will also need to make the following changes:
+
+ .. code-block:: bash
+
+ expose:
+ - 6969
+ - 9696
+
+ will need to be changed to:
+
+ ports:
+ - "6969:6969"
+ - "9696:9696"
+
+**Step 4:** Start containers and interact with PDP-D.
+
+ .. code-block:: bash
+
+ docker-compose -f scripts/policy/docker-compose-drools-apps.yml up -d
+ docker container ls
+ docker exec -it drools bash
+
+ .. image:: img/docker/dockerComposeUp.png
+
+ .. code-block:: bash
+
+ policy status
+
+ .. image:: img/docker/policyStatus.png
+
+ .. code-block:: bash
+
+ # launches subshell where telemetry commands can be executed
+ telemetry
+
+ ls
+
+ cd controllers
+
+ # Get the current controllers
+ get
+
+ .. image:: img/docker/telemetryCmd.png
+
+ .. code-block:: bash
+
+ # Get information about the "frankfurt" controller
+ get frankfurt
+
+ .. image:: img/docker/getFrankfurt.png
+
+
+ .. code-block:: bash
+
+ docker-compose -f scripts/policy/docker-compose-drools-apps.yml down -v
+
+ .. image:: img/docker/dockerComposeDown.png
+
+In the next section, you will see more about using telemetry commands and interacting with the PDP-D.
+
+Using Eclipse
+^^^^^^^^^^^^^
+
+**Step 1:** Clone 'drools-pdp' repository and create a new directory for eclipse workspace.
+
+Link to repository: https://gerrit.onap.org/r/admin/repos/policy/drools-pdp
+For the purposes of this demo, we will create an new directory to use as a workspace for eclipse.
+
+ .. code-block:: bash
+
+ $ git clone "https://gerrit.onap.org/r/policy/drools-pdp"
+ Cloning into 'drools-pdp'...
+ remote: Counting objects: 59, done
+ remote: Finding sources: 100% (30/30)
+ remote: Total 14406 (delta 0), reused 14399 (delta 0)
+ Receiving objects: 100% (14406/14406), 3.23 MiB | 628.00 KiB/s, done.
+ Resolving deltas: 100% (6630/6630), done.
+ Checking out files: 100% (588/588), done.
+
+ $ mkdir workspace-drools-pdp
+
+ $ ls
+ drools-pdp/ workspace-drools-pdp/
+
+The "drools-pdp/" directory contains the cloned repository and "workspace-drools-pdp/" is an empty directory.
+
+**Step 2:** Import "drools-pdp" as an existing maven project.
+
+Open Eclipse. Hit the **browse** button and navigate to the "workspace-drools-pdp/" directory. Select that folder as the workspace directory and hit **launch**.
+
+ .. image:: img/eclipse/selectDirectory.png
+
+Select File -> Import -> Maven -> Existing Maven Projects -> Next
+
+ .. image:: img/eclipse/importMavenProject.png
+
+Select **Browse** and navigate to the root directory of the cloned project. Hit **Select All** to make sure all projects are included and select **Finish**.
+
+ .. image:: img/eclipse/selectProjectsToImport.png
+
+**Step 3:** Run "policy-management" as a java application
+
+All of the projects will appear in the package explorer after they finish importing. Right click on "policy-management", select "Run As", and select "Java Application".
+
+ .. image:: img/eclipse/runAsJavaApp.png
+
+Type "main" and select the option "Main - org.onap.policy.drools.system" then hit **OK**.
+
+ .. image:: img/eclipse/mainAppSelection.png
+
+If everything is successful, the PDP-D will start running and you will notice output displayed in the console. In the next section, you will see how to interact with the PDP-D using telemetry commands.

High Level Architecture
^^^^^^^^^^^^^^^^^^^^^^^
The vCPE flow begins with an onset message that is sent from DCAE notifying the PDP-D that an action needs to be taken on a VM/VNF. Once the PDP-D has inserted the onset into drools memory, rules begin to fire to start processing the onset for the vCPE policy that exists in drools memory. If the onset is not enriched with A&AI data, Policy will query A&AI for the VM/VNF data otherwise the PDP-D will get the A&AI data needed directly from the onset. A Guard query is then executed to determine if the action to be taken is allowed. If Guard returns a permit, the PDP-D will then send an APPC Restart recipe request to restart the VM/VNF specified in the request. If APPC is successful then the PDP-D will send a operation success notification on the POLICY-CL-MGT topic. The PDP-D waits for an abatement message to come from DCAE before ending the transaction. Once the abatement is received the PDP-D sends a final success notification and gracefully ends processing the event.

^^^^^^^^^^^^^^^^^^^^^^^
The vFW flow begins with an onset message that is sent from DCAE notifying the PDP-D that an action needs to be taken on a VNF. Once the PDP-D has inserted the onset into drools memory, rules begin to fire to start processing the onset for the vFW policy that exists in drools memory. If the onset is not enriched with A&AI data, Policy will query A&AI for the VNF data otherwise the PDP-D will get the A&AI data needed directly from the onset. Then an A&AI named query is executed on the source VNF entity from the onset to find the target VNF entity that the PDP-D will take action on. Once the target entity is retrieved from A&AI, a Guard query is executed to determine if the action to be taken is allowed. If Guard returns a permit, the PDP-D will then send an APPC ModifyConfig recipe request to modify pg-streams as specified in the request payload. If APPC is successful then the PDP-D will send a final success notification on the POLICY-CL-MGT topic and gracefully end processing the event.

- For vLBS Use Case, the following steps are required to setup the service instance:
- Create a Service Instance via VID.
- Create a VNF Instance via VID.
- - Preload SDNC with topology data used for the actual VNF instantiation (both base and DNS scaling modules). NOTE: you may want to set “vlb_name_0” in the base VF module data to something unique. This is the vLB server name that DCAE will pass to Policy during closed loop. If the same name is used multiple times, the Policy name-query to AAI will show multiple entries, one for each occurrence of that vLB VM name in the OpenStack zone. Note that this is not a limitation, typically server names in a domain are supposed to be unique.
- - Instantiate the base VF module (vLB, vPacketGen, and one vDNS) via VID. NOTE: The name of the VF module MUST start with ``Vfmodule_``. The same name MUST appear in the SDNC preload of the base VF module topology. We’ll relax this naming requirement for Beijing Release.
- - Run heatbridge from the Robot VM using ``Vfmodule_`` … as stack name (it is the actual stack name in OpenStack)

ONAP Supported Policy Types
***************************
-In ONAP the following Policy Types are supported. Each Policy Type is implemented as an application that extends the **XacmlApplicationServiceProvider**. For details on each implementation, please refer to the `applications submodule of the onap/xacml-pdp project <https://gerrit.onap.org/r/gitweb?p=policy/xacml-pdp.git;a=tree;f=applications;h=047878fe14851d8a51998e065b8aca583ed8c994;hb=refs/heads/elalto>`__.

By cloning the policy/xacml-pdp repository, one can run the JUnit tests to get a better understanding on how applications are built using translators and the XACML Policies that are generated for each Policy Type. Each application supports one or more Policy Types and an associated "action" used by the Decision API when making these calls.

+Native XACML Policy Type
+=======================
+This Policy type is used by any client or ONAP component who has the need of native XACML evaluation. A native XACML policy or policy set encoded in XML can be created off this policy type and loaded into the XACML PDP engine by invoking the PAP policy deployment API. Native XACML requests encoded in either JSON or XML can be sent to the XACML PDP engine for evaluation by invoking the native decision API. Native XACML responses will be returned upon evaluating the requests against the matching XACML policies. Those native XACML policies, policy sets, requests and responses all follow the `OASIS XACML 3.0 Standard <https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=xacml>`__.

+
+According to the XACML 3.0 specification, two content-types are supported and used to present the native requests/responses. They are formally defined as "application/xacml+json" and "application/xacml+xml".

Supporting Custom Policy Types
******************************
In order to support your own custom Policy Type that the XACML PDP Engine can support, one needs to build a Java service application that extends the **XacmlApplicationServiceProvider** interface and implement a **ToscaTranslator** application. Your application should register itself as a Java service application and expose it in the classpath used to be loaded into the ONAP XACML PDP Engine. Ensure you define and create the TOSCA Policy Type according to these :ref:`Policy Design and Development <design-label>`. You should be able to load your custom Policy Type using the :ref:`Policy Lifecycle API <api-label>`. Once successful, you should be able to start creating policies from your custom Policy Type.
