SO Sub-Components
------------------
**API Handler**
RESTful interface to northbound clients
-
- * Handle service-level and infrastructure (VNF & network) requests
-
+
+* Handle service-level and infrastructure (VNF & network) requests
+
Service-agnostic APIs
- * “Service Instantiation API”
+ * "Service Instantiation API"
Model-driven recipe selection
* Use SO Catalog to map input requests to BPMN flows
* Dynamic lookup based on service-model + action
* Input data forwarded to BPMN flow
-
+
Track open and completed requests via SO Request DB
Multiple API-H modules may support different APIs
Expose RESTful interface to API-H (unique path per recipe)
- Make use of common “building block” sub-flows
+ Make use of common "building block" sub-flows
Sequence orchestration steps for each Resource in the recipe
* Request and configure network resources via SDN-C
* Manage cloud resources via PO (OpenStack)
* Update inventory via A&AI
-
+
Perform error handling/rollback
**Resource Adapters**
Interfaces to lower level controllers and other ONAP components
- * Platform Orchestrator, SDN-Controller, APP-Controller, VFC-Controllers
+ * Platform Orchestrator, SDN-Controller, APP-Controller, VFC-Controllers, Multi-Cloud
* Hides the details of complex interfaces (e.g. OpenStack APIs)
* Expose interfaces to BPMN flows as SOAP or REST APIs
* Support synchronous and asynchronous operations
-
+
Provided as part of SO platform for use by all BPMN flows
Use SO Catalog to map resource requests to a recipe/template
* Merge input parameters with templates at run-time
**Data Stores**
-
+
Request DB
* Tracks open and completed requests
-
+
SO Catalog
* SO view of the SDC Catalog
* service and resource models, recipes, and templates
Camunda DB
* Maintain state for BPMN flows
* Supports multiple active engines
-
+
**SDC Distribution Client**
Receive updated service models from SDC
* Event-bus notifications when new models available
* HTTP retrieval of models (TOSCA) and artifacts (Heat)
-
+
Receive distributions as TOSCA models
Populate SO Catalog
**SO Monitoring**
Monitor BPMN Workflow execution by providing
- * Service list search based on search criteria
- * Service statistic
- * Service Process Instance Rendering and Detail
-
+ * Service list search based on search criteria
+ * Service statistic
+ * Service Process Instance Rendering and Detail
+
+**SO VNFM Adapter**
+
+ Support external SVNFMs through SOL003 APIs
+ * Create, Instantiate, Terminate and Delete VNF, including Granting, Subscription and Lifecycle Notifications
+ * Tracking capability which VNFM instance has handled with which VNF instance
+ * BPMN Building Block workflows and Java-based recipes for VNF LCM
+ * VNFM Simulator for validating SO VNFM Adapter NBI and SBI for integration testing
+ * The SO ETSI CSIT Tests and running them, https://wiki.onap.org/display/DW/SO+ETSI+CSIT
+ * Testing the SO ETSI Alignment manually (Instantiate VNF using SVNFM), https://wiki.onap.org/pages/viewpage.action?pageId=68524128
