What is this release trying to address?

• TSC Must Have Requirements for ExtAPI - as per EXTAPI-344 
  • Document current upgrade component strategy (TSC must have)  
  • SECCOM Perform Software Composition Analysis - Vulnerability tables (TSC must have)
  • SECCOM Password removal from OOM HELM charts (TSC must have)
  • SECCOM HTTPS communication vs. HTTP (TSC must have) - CLAMP has already moved to to HTTPS so no work is required here
• Deliver increased interoperability between ONAP and External Systems ( e.g. Service Catalog Notifications )
  

...

• • Service

...

• • Catalog -
    • Add notification for serviceCatalog API
      
      • Description:
        
        • Allow BSS catalog function to receive service catalog notification as serviceSpec status change or characteristic change (new value in an enum list for example). Could be interesting to track these serviceSpec update to update accordingly productSpec
      • Relevance:
      • Complexity: Moderate - need to subscribe to authenticated topic
      • Prerequisites: It requires to have a notification from SDC via DMaaP
      • Resources: Adrian O'Sullivan
    • (Specification Focus) Analysis of new Operation Domain Manager APIs in SDC and impact on support POST for ServiceSpecification Resource. Currently Telstra are working on SDC APIs for onboarding a Partner ServiceSpecification reference in SDC with all the information to communicate with Partners External APIs for Service Instantiation. ( Stretch goal - resources permitted to look at supporting POST ServiceSpecifcation - potential to use jolt to transform to new SDC API format.
• Continue to enhance ONAP External APIs exposed to BSS/OSS (e.g. Increase support for SO Service APIs , macro mode)
  • Service Ordering
    
    • Add Support for serviceOrder API for Service Instantiation via macro mode
      
      • Description: 

        • With Dublin, a new mode is available in SO to instantiate a service : the "macro" mode.

          In SDC, a service can be declared with an instantiationType equal to "A-la-carte" or equal to "Macro". This information is then available in the Tosca service definition file.

          When "Macro" mode is chosen for a service, the SO will use different kind of BPMN workflow.

          This "macro" mode need to be managed by NBI.

          NBI needs to look at service definition in Tosca file, select the mode, build the "macro" request toward SO  when service instantiationType is "Macro". 

          REQUEST 1 : NBI have to send a request to SO with the parameter "aLaCarte": false when instantiationType is Macro in service definition file

          In macro mode, the SO request may also contain, in the "userParams" section, all needed information about VNFs and VF-module(s) to be instantiated.

          All those necessary information are in the Tosca service definition file generated by SDC.

          If NBI do not fill those information, the serviceOrder sent to NBI will have to provide those informations (that means an external system will have to do the job)

          REQUEST 2 : NBI to look at VNF, VF-module and Network in the Tosca service definition file in order to build the full "macro" request toward SO.

      • Relevance:
      • Complexity: High
      • Prerequisites: 
      • Resources: Romain and Rene
    • Update serviceOrder API to use GR_API
      
      • Description: 

        • SO can use two kind of API with SDNC : Generic-Resource API (GR_API) or VNF_API.It seems that it is better to indicate to SO to use GR_API now. It is the value of the field "testApi" that need to be modified in SO request to instantiate service object. Can be an environment variable.

      • Relevance:
      • Complexity: Easy
      • Prerequisites: 
      • Resources: Romain
    • Handle action modify in ServiceOrder in a manner other than recreate Service 
      
      • Description: 

        • 5G Network Slicing plan to have new SO capability for Service Modifications, specifically allowing an instantiated and activated service to be deactivated without being deleted.

      • Relevance:
      • Complexity: Moderate
      • Prerequisites: 
      • Resources: Adrian O'Sullivan
    • Update ServiceOrder to accommodate Service Characteristics of "object" type
      
      • Description: 

        • Need to handle service orders which use "object" type in the serviceCharacteristics, i.e. utiizing the new specificationInputSchema . Also update the object to be stored as "object" v "Object" in the service catalog response.

      • Relevance:
      • Complexity: Easy
      • Prerequisites: 
      • Resources: Adrian O'Sullivan - Note work complete
  • Performance Management (specification focus) (stretch goal: implementation associated with Network Slicing KPI reporting)
  • Integration 
    • Integrate External API/NBI within ONAP DMaap for authenticated topics ( Adrian )
    • Integrate External API/NBI with AAF for security enhancement, introduce https support  ( Matthieu )

Use Cases

The existing use cases are still going to be supported ( BBS, CCVPN ) and additional use cases will be supported for the Frankfurt Release (as defined by the Control loop sub committee and TSC).

5G Network Slicing Use case is a new use case which have plans to use External API Service Order APIs to Create, Delete and modify Communication Services. The hope is to reuse existing Service Order APIs. Some enhancements may be needed, mainly in the ability to modify a service ( updateType, pending support from SO ) plus allowing serviceType to be an optional parameter in the Service Order ( used in AAI ).
