  • 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
    • Operation Domain Manager ( stretch goal ) specification focus around supporting POST of partner ServiceSpecification  EXTAPI-351 - Getting issue details... STATUS (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 in  EXTAPI-258 - Getting issue details... STATUS
      
      • 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  -  EXTAPI-337 - Getting issue details... STATUS
      
      • 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
    • 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 
    • ( stretch goal ) Specification work on how to 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
  • Performance Management (stretch goal ) specification focus: specification work associated with Network Slicing KPI reporting.
  • Operation Domain Manager ( stretch goal ) specification focus around supporting POST of partner ServiceSpecification  EXTAPI-351 - Getting issue details... STATUS
  • 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 ). Wipro has taken ownership of  EXTAPI-349 - Getting issue details... STATUS  for enhancements needed. 

Impact assessment completed by Adrian, updates only to support Service Ordering considered in Frankfurt timescale.

Epics

Stories

Longer term Roadmap

Indicate at a high level the longer term roadmap. This is to put things into the big perspective.

Provide a clear and unambiguous ONAP service abstraction so that the BSS/OSS can exchange service requirements and service capabilities in a common and consistent fashion.
Provide a way to rapidly integrate new Services and Service Components into ONAP so that they can quickly introduce capabilities for their customers and within their infrastructure.
Enable management the entire lifecycle of Services within ONAP in a common way so that they can ensure orchestration, manageability and control of each Service in an easily integrateable and low cost way.
Model Driven approach: a cohesive way to have a shared view of information across ONAP external interfaces that can be used for or be input into a model driven process whereby the cost of delivering platform functionality is drastically reduced and the time to delivery is dramatically decreased.

It is envisioned that from a Service Provider to BSS/OSS interaction context (i.e. MEF Legato), the ONAP External API will support the following types of interacts:

• BSS/OSS retrieves Service Models
• BSS/OSS requests service feasibility determination.
• BSS/OSS requests reservations of capabilities related to a potential Service.
• BSS/OSS requests activation of Service.
• BSS/OSS receives Service activation tracking status updates.
• BSS/OSS retrieves Service Inventory
• BSS/OSS receives usage events due to a Customer initiating dynamic activity on their Service (e.g., increase in bandwidth).
• BSS/OSS receives a summary of Service quality and usage information.
• BSS/OSS receives Service state and fault event information
• BSS/OSS receives Service Activation Testing results.
• BSS/OSS receive capability information about the Service layer.
• BSS/OSS manages Licenses
• BSS/OSS receives License Usage information

It is envisioned that from a Service Provider to Partner Provider interaction context (i.e. MEF Interlude), the ONAP External API will support the following types of interacts:

• Service Provider controls aspects of the Service within the Partner domain (on behalf of the Customer) by requesting changes to dynamic parameters as permitted by service policies.
• Service Provider queries state of the Service.
• Service Provider requests change to administrative state or permitted attributes of a Service.
• Service Provider request creation of connectivity between two Service Interfaces as permitted by established business arrangement.
• Service Provider request instantiation of functional service components as permitted by established business arrangement.
• Service Provider queries the Partner for detailed information related to Services provided by the Partner to the Service Provider.
• Service Provider receives Service specific event notifications (e.g., Service Problem Alerts) from the Partner.
• Service Provider receives Service specific performance information from the Partner.
• Service Provider request Service related test initiation and receive test results from the Partner.
