+ONAP installs a DNS server used to resolve IP addresses in the ONAP OAM private network. ONAP Amsterdam Release also requires OpenStack Designate DNS support for the DCAE platform, so as to allow IP address discovery and communication among DCAE elements. This is required because the ONAP HEAT template only installs the DCAE bootstrap container, which will in turn install the entire DCAE platform. As such, at installation time, the IP addresses of the DCAE components are unknown. The DNS server that ONAP installs needs to be connected to the Designate DNS to allow communication between the DCAE elements and the other ONAP components. To this end, dns\_list, external\_dns, and dns\_forwarder should all have the IP address of the Designate DNS. These three parameters are redundant, but still required for Amsterdam Release. Originally, dns\_list and external\_dns were both used to circumvent some limitations of older OpenStack versions. In future releases, the DNS settings and parameters in HEAT will be consolidated. The Designate DNS is configured to access the external DNS. As such, the ONAP DNS will forward to the Designate DNS the queries from ONAP components to the external world. The Designate DNS will then forward those queries to the external DNS.
-DCAE spins up ONAP's data collection and analytics system in two phases. The first is the launching of a bootstrap VM that is specified in the ONAP Heat template. This VM requires a number of deployment specific conifiguration parameters being provided so that it can subsequently bring up the DCAE system. There are two groups of parameters. The first group relates to the launching of DCAE VMs, including parameters such as the keystone URL and additional VM image IDs/names. DCAE VMs are connected to the same internal network as the rest of ONAP VMs, but dynamically spun up by the DCAE core platform. Hence these parameters need to be provided to DCAE. Note that although DCAE VMs will be launched in the same tenant as the rest of ONAP, because DCAE may use MultiCloud node as the agent for interfacing with the underying cloud, it needs a separate keystone URL (which points to MultiCloud node instead of the underlying cloud). The second group of configuration parameters relate to DNS As A Service support (DNSaaS). DCAE requires DNSaaS for registering its VMs into organization-wide DNS service. For OpenStack, DNSaaS is provided by Designate. Designate support can be provided via an integrated service endpoint listed under the service catalog of the OpenStack installation; or proxyed by the ONAP MultiCloud service. For the latter case, a number of parameters are needed to configure MultiCloud to use the correct Designate service. These parameters are described below:

-VNFs HEAT Templates
+vFirewall Use Case
---
-The HEAT templates for the demo applications are stored in heat/vFW and heat/vLB directories.
+The use case is composed of three virtual functions (VFs): packet generator, firewall, and traffic sink. These VFs run in three separate VMs. The packet generator sends packets to the packet sink through the firewall. The firewall reports the volume of traffic passing though to the ONAP DCAE collector. To check the traffic volume that lands at the sink VM, you can access the link http://sink\_ip\_address:667 through your browser and enable automatic page refresh by clicking the "Off" button. You can see the traffic volume in the charts.
-vFW contains the HEAT template, base_vfw.yaml, and the environment file, base_vfw.env, that are used to instantiate a virtual firewall. The VNF is composed of three VMs:
- - Packet generator
- - Firewall
- - Sink
+The packet generator includes a script that periodically generates different volumes of traffic. The closed-loop policy has been configured to re-adjust the traffic volume when high-water or low-water marks are crossed.
-The packet generator generates traffic that passes through the firewall and reaches the sink. The firewall periodically reports the number of packets received in a unit of time to the DCAE collector. If the reported number of packets received on the firewall is above a high-water mark or below a low-water mark, ONAP will enforce a configuration change on the packet generator, reducing or augmenting the quantity of traffic generated, respectively.
+__Closed-Loop for vFirewall demo:__
-vLB contains the HEAT template, base_vlb.yaml, and the environment file, base_vlb.env, that are used to spin up a virtual load balancer and a virtual DNS. vLB also contains the HEAT template, packet_gen_vlb.yaml, and the environment file packet_gen_vlb.env, of a packet generator that generates DNS queries.
-The load balancer periodically reports the number of DNS query packets received in a time unit to the DCAE collector. If the reported number of received packets crosses a threshold, then ONAP will spin up a new DNS based on the dnsscaling.yaml HEAT template and dnsscaling.env to better balance the load of incoming DNS queries.
+Through the ONAP Portal's Policy Portal, we can find the configuration and operation policies that are currently enabled for the vFirewall use case.
-The vFW and vLB HEAT templates and environment files are onboarded into ONAP SDC and run automatically. The user is not required to run these templates manually.
-However, before onboarding the templates following the instructions in the ONAP documentation, the user should set the following values in the environment files:
+- The configuration policy sets the thresholds for generating an onset event from DCAE to the Policy engine. Currently, the high-water mark is set to 700 packets while the low-water mark is set to 300 packets. The measurement interval is set to 10 seconds.
+- When a threshold is crossed (i.e. the number of received packets is below 300 packets or above 700 packets per 10 seconds), the Policy engine executes the operational policy to request APPC to adjust the traffic volume to 500 packets per 10 seconds.
+- APPC sends a request to the packet generator to adjust the traffic volume.
+- Changes to the traffic volume can be observed through the link http://sink\_ip\_address:667.

-ONAP Demo applications
----
+__Adjust packet generator:__
-Demo applications are installed and run automatically when the VNFs are instantiated. The user is not supposed to download and install the demo applications manually.
+The packet generator contains 10 streams: fw\_udp1, fw\_udp2, fw\_udp3, . . . , fw\_udp10. Each stream generates 100 packets per 10 seconds. A script in /opt/run\_traffic\_fw\_demo.sh on the packet generator VM starts automatically and alternates high traffic (i.e. 10 active streams at the same time) and low traffic (1 active stream) every 5 minutes.
-Two demo applications, vFirewall and vLoadBalancer/vDNS are included.
+To enable a stream, include *{"id":"fw_udp1", "is-enabled":"true"}* in the *pg-stream* bracket.
-vFirewall
----
+To adjust the traffic volume produced by the packet generator, run the following command in a shell, replacing PacketGen_IP in the HTTP argument with localhost (if you run it in the packet generator VM) or the packet generator IP address:
-The vFirewall application contains 3 VMs: a firewall, a packet generator, and a packet sink.
-The packet generator sends packets to the packet sink through the firewall. The firewall reports the volume of traffic from the packet generator to the sink to ONAP DCAE’s collector. To check the traffic volume to the sink, you can access the link http://sink_ip_address:667 through your browser. You can see the traffic volume in the charts.
+ curl -X PUT -H "Authorization: Basic YWRtaW46YWRtaW4=" -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"pg-streams":{"pg-stream": [{"id":"fw_udp1", "is-enabled":"true"},{"id":"fw_udp2", "is-enabled":"true"},{"id":"fw_udp3", "is-enabled":"true"},{"id":"fw_udp4", "is-enabled":"true"},{"id":"fw_udp5", "is-enabled":"true"}]}}' "http://PacketGen_IP:8183/restconf/config/sample-plugin:sample-plugin/pg-streams"
-The packet generator includes a script that periodically generates different volumes of traffic.
+The command above enables 5 streams.
-The closed-loop policy has been configured to re-adjust the traffic volume when it is needed.
-__Closedloop for vFirewall demo:__
+vLoadBalancer/vDNS Use Case
+---
-Through the ONAP Portal’s Policy Portal, we can find the configuration and operation policies that is currently enabled for the vFirewall application.
-+ The configuration policy sets the thresholds for generating an onset event from DCAE to the Policy engine. Currently the thresholds are set to 300 packets and 700 packets, while the measurement interval is set to 10 seconds.
-+ Once one of the thresholds is crossed (e.g. the number of received packets is below 300 packets or above 700 per 10 seconds), the Policy engine executes the operational policy to request APP-C to change the configuration of the packet generator.
-+ APP-C sends a request to the packet generator to adjust the traffic volume to 500 packets per 10 seconds.
-+ The traffic volume can be observed through the link http://sink_ip_address:667.
+The use case is composed of three VFs: packet generator, load balancer, and DNS server. These VFs run in three separate VMs. The packet generator issues DNS lookup queries that reach the DNS server via the load balancer. DNS replies reach the packet generator via the load balancer as well. The load balancer reports the average amount of traffic per DNS over a time interval to the DCAE collector. When the average amount of traffic per DNS server crosses a predefined threshold, the closed-loop is triggered and a new DNS server is instantiated.
-__Adjust packet generator:__
+To test the application, you can run a DNS query from the packet generator VM:
-The packet generator contains 10 streams: fw_udp1, fw_udp2, fw_udp3,...fw_udp10. Each stream generates 100 packets per 10 seconds.
+ dig @vLoadBalancer_IP host1.dnsdemo.onap.org
-To enable a stream, include *{"id":"fw_udp1", "is-enabled":"true"}* in the *pg-stream* bracket.
+The output below means that the load balancer has been set up correctly, has forwarded the DNS queries to one DNS instance, and the packet generator has received the DNS reply message.

+Through the Policy Portal (accessible via the ONAP Portal), we can find the configuration and operation policies that are currently enabled for the vLoadBalancer/vDNS application.
++ The configuration policy sets the thresholds for generating an onset event from DCAE to the Policy engine. Currently, the threshold is set to 200 packets, while the measurement interval is set to 10 seconds.
++ Once the threshold is crossed (e.g. the number of received packets is above 200 packets per 10 seconds), the Policy engine executes the operational policy. The Policy engine queries A&AI to fetch the VNF UUID and sends a request to SO to spin up a new DNS instance for the VNF identified by that UUID.
++ SO spins up a new DNS instance.
-A script in /opt/run_traffic_fw_demo.sh on the packet generator VM starts automatically and alternate the volume of traffic every 5 minutes.

----
+To change the volume of queries generated by the packet generator, run the following command in a shell, replacing PacketGen_IP in the HTTP argument with localhost (if you run it in the packet generator VM) or the packet generator IP address:
-The vLoadBalancer/vDNS app contains 2 VMs in the base model: a load balancer and a DNS instance. When there are too many DNS queries, the closed-loop is triggered and a new DNS instance will be spun up.
+ curl -X PUT -H "Authorization: Basic YWRtaW46YWRtaW4=" -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"pg-streams":{"pg-stream": [{"id":"dns1", "is-enabled":"true"}]}}' "http://PacketGen_IP:8183/restconf/config/sample-plugin:sample-plugin/pg-streams"
+
++ *{"id":"dns1", "is-enabled":"true"}* shows the stream *dns1* is enabled. The packet generator sends requests in the rate of 100 packets per 10 seconds.
-To test the application, in the command prompt:
++ To increase the amount of traffic, you can enable more streams. The packet generator has 10 streams, *dns1*, *dns2*, *dns3* to *dns10*. Each of them generates 100 packets per 10 seconds. To enable the streams, please add *{"id":"dnsX", "is-enabled":"true"}* to the pg-stream bracket of the curl command, where *X* is the stream ID.
-```
-# nslookup host1.dnsdemo.onap.org *vLoadBalancer_IP*
+For example, if you want to enable 3 streams, the curl command will be:
-Server: *vLoadBalancer_IP*
-Address: *vLoadBalancer_IP*
+ curl -X PUT -H "Authorization: Basic YWRtaW46YWRtaW4=" -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"pg-streams":{"pg-stream": [{"id":"dns1", "is-enabled":"true"}, {"id":"dns2", "is-enabled":"true"},{"id":"dns3", "is-enabled":"true"}]}}' "http://PacketGen_IP:8183/restconf/config/sample-plugin:sample-plugin/pg-streams"
-Name: host1.dnsdemo.onap.org
-Address: 10.0.100.101
+When the VNF starts, the packet generator is automatically configured to run 5 streams.

+vVolumeGroup Use Case
+---
-That means the load balancer has been set up correctly and has forwarded the DNS queries to the DNS instance.
+The vVG directory contains the HEAT template (base\_vvg.yaml) and environment file (base\_vvg.env) used to spin up a volume group in OpenStack and attach it to an existing ONAP instance.
-__Closedloop for vLoadBalancer/vDNS:__
+The HEAT environment file contains two parameters:
-Through the Policy Portal (accessible via the ONAP Portal), we can find the configuration and operation policies that are currently enabled for the vLoadBalancer/vDNS application.
-+ The configuration policy sets the thresholds for generating an onset event from DCAE to the Policy engine. Currently the threshold is set to 200 packets, while the measurement interval is set to 10 seconds.
-+ Once the threshold is crossed (e.g. the number of received packets is above 200 packets per 10 seconds), the Policy engine executes the operational policy to query A&AI and send a request to MSO for spinning up a new DNS instance.
-+ A new DNS instance will be then spun up.
+ volume_size: 100
+ nova_instance: 1234456
+volume\_size is the size (in gigabytes) of the volume group. nova\_instance is the name or UUID of the VM to which the volume group will be attached. This parameter should be changed appropriately.
-__Generate DNS queries:__
-To generate DNS queries to the vLoadBalancer/vDNS instance, a separate packet generator is prepared for this purpose.
+ONAP Use Cases HEAT Templates
+---
-1. Spin up the heat template in the repository: https://link_to_repo/demo/heat/vLB/packet_gen_vlb.yaml.
+USE CASE VNFs SHOULD BE INSTANTIATED VIA ONAP. THE USER IS NOT SUPPOSED TO DOWNLOAD THE HEAT TEMPLATES AND RUN THEM MANUALLY.
-2. Log in to the packet generator instance through ssh.
+The vFWCL directory contains two HEAT templates, one for creating a packet generator (vPKG/base\_vpkg.yaml) and one for creating a firewall and a packet sink (vFWSNK/base\_vfw.yaml). This use case supports VNF onboarding, instantiation, and closed-loop. The vFW directory, instead, contains a single HEAT template (base\_vfw) that spins up the three VFs. This use case supports VNF onboarding and instantiation only (no support for closed-loop). For Amsterdam Release, the HEAT templates in vFWCL are recommended, so that users can test and demonstrate the entire ONAP end-to-end flow.
-3. Change the IP address in the config file /opt/config/vlb_ipaddr.txt to the public IP address of the LoadBalancer instance.
+The vLB directory contains a base HEAT template (base\_vlb.yaml) that install a packet generator, a load balancer, and a DNS instance, plus another HEAT template (dnsscaling.yaml) for the DNS scaling scenario, in which another DNS server is instantiated.
-4. Execute the script /opt/vdnspacketgen_change_streams_ports.sh to restart sending the DNS queries to the new LoadBalancer address.
+Before onboarding the VNFs in SDC, the user should set the following values in the HEAT environment files:
-5. To change the volume of queries, execute the following command in a command prompt with the updated vLoadBalancer_IP address or localhost in the http argument:
-
-```
-curl -X PUT -H "Authorization: Basic YWRtaW46YWRtaW4=" -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"pg-streams":{"pg-stream": [{"id":"dns1", "is-enabled":"true"}]}}' "http://vLoadBalancer_IP:8183/restconf/config/sample-plugin:sample-plugin/pg-streams"
-```
-+ *{"id":"dns1", "is-enabled":"true"}* shows the stream *dns1* is enabled. The packet generator sends requests in the rate of 100 packets per 10 seconds.
+ image_name: PUT THE VM IMAGE NAME HERE
+ flavor_name: PUT THE VM FLAVOR NAME HERE
+ public_net_id: PUT THE PUBLIC NETWORK ID HERE
+ dcae_collector_ip: PUT THE ADDRESS OF THE DCAE COLLECTOR HERE (NOTE: this is not required for vFWCL/vPKG/base\_vpkg.env)
+ pub_key: PUT YOUR KEY HERE
+ cloud_env: PUT openstack OR rackspace HERE
+
+image\_name, flavor\_name, \public\_net\_id, and pub\_key can be obtained as described in the ONAP Section. For deployment in OpenStack, cloud\_env must be openstack.
-+ To increase the amount of traffic, we can enable more streams. The packet generator has 10 streams, *dns1*, *dns2*, *dns3* to *dns10*. Each of them generates 100 packets per 10 seconds. To enable the streams, please insert *{"id":"dnsX", "is-enabled":"true"}* where *X* is the stream ID in the pg-stream bracket of the curl command.
-For example, if we want to enable 3 streams, the curl command should be:
+The DNS scaling HEAT environment file for the vLoadBalancer use case also requires you to specify the private IP of the load balancer, so that the DNS can connect to the vLB:
+
+ vlb_private_ip_1: PUT THE PRIVATE ADDRESS OF THE VLB IN THE ONAP NETWORK SPACE HERE
-```
-curl -X PUT -H "Authorization: Basic YWRtaW46YWRtaW4=" -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"pg-streams":{"pg-stream": [{"id":"dns1", "is-enabled":"true"}, {"id":"dns2", "is-enabled":"true"},{"id":"dns3", "is-enabled":"true"}]}}' "http://vLoadBalancer_IP:8183/restconf/config/sample-plugin:sample-plugin/pg-streams"
-```
+As an alternative, it is possible to set the HEAT environment variables after the VNF is onboarded via SDC by appropriately preloading data into SDNC. That data will be fetched and used by SO to overwrite the default parameters in the HEAT environment file before the VNF is instantiated. For further information about SDNC data preload, please visit the wiki page: https://wiki.onap.org/display/DW/Tutorial_vIMS+%3A+SDNC+Updates
+
+Each VNF has a MANIFEST.json file associated with the HEAT templates. During VNF onboarding, SDC reads the MANIFEST.json file to understand the role of each HEAT template that is part of the VNF (e.g. base template vs. non-base template). VNF onboarding requires users to create a zip file that contains all the HEAT templates and the MANIFEST file. To create the zip file, you can run the following command from shell:
-
+ cd VNF_FOLDER (this is the folder that contains the HEAT templates and the MANIFEST file)
+ zip ZIP_FILE_NAME.zip *
+
