Overview

...

• • Deliver points of interoperability between ONAP and External Systems
  • Initial focus Focus on ONAP External APIs to BSS/OSS (i.e., MEF Legato)
    • Service CatalogLicense Usage (stretch goal) (specification focus)
      • Service Ordering (including Service Instantiation)
      • Service Inventory (specification focus) (stretch goal: implementation)
      • Service Topology (stretch goal) (specification focus)
      • • 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: Easy
          • Prerequisites: It requires to have a notification from SDC because NBI will not pool AAI
          • Resources:
        • Improve ServiceCatalog API for service characteristics
          
          • Description:
            
            • Expose from NBI json (or other format) file describing the serviceSpec characteristic (same type of file we can retrieve on MEF Git Hub to describe an UNISpec for example)
            • Convert YAML in CSAR to ONAP wide consistent JSON schema for Service Characteristic Input parameters and provide across the ServiceCatalog API
          • Relevance:
          • Complexity: Easy
          • Prerequisites: Need SDC improvements
          • Resources:
      • Service Ordering
        
        • Add Service Request Status for serviceOrder API
          
          • Description: 

            • Provide summary and detailed status for both Infrastructure requested VNFs and Customer requested VNFs.

            • Requestors that create transaction requests on the ONAP Platform, have a need to effectively manage the requests they create.  The Requestor is the responsible owner for the transaction and thus, need the ability to have visibility into the status of their requests

            • BSS/OSS system will call the API providing one of the following options:
              1.Specific Service Request ID
              2.Many Service Requests based on Selection Criteria such as: Service Request Status and/or Time Frame where appropriate, (e.g., past day completions)

              ONAP will respond with the current status of the workflow for the selected request(s).  The status can include not only a status summary of the requests but also the steps taken, start/stop time of the steps taken, notifications generated, and the remaining steps that need to be taken.  Different workflows will have different numbers of steps, so this API will need to provide a name or identifier for any and all steps
          • Relevance:
          • Complexity: Easy
          • Prerequisites: Could implement in two phases, 1st phase implement status details that are currently available in the Service Orchestration (SO) API, while the 2nd phase would enhance SO and/or the SO API with any additional status information
          • Resources:
        • Add notification for serviceOrder API
          
          • Description: 
            • Allow BSS (or any other) system to receive order/OrderItem update. BSS (or any other system) will not have to pool. We can allow several distinct notification (Nice to have: let subscriber specify notification contains). Minimum is to provide ServiceOrderStateChangeNotifications etc to HUB subscriber. After if we’re able to get a notification from SO it will be perfect but initial requirement is only at external API northbound
            • Notifications related to ServiceOrder: - ServiceOrderCreationNotification - ServiceOrderAttributeValueChangeNotification - ServiceOrderStateChangeNotification - ServiceOrderInformationRequiredNotification - ServiceOrderRemoveNotification
          • Relevance:
          • Complexity: Easy
          • Prerequisites: Nothing for basic deliver…SO notifications to have high performance (without SO notification, NBI will pool SO as of today)
          • Resources:
        • Update ServiceOrder to to accommodate Service Chaining.
          
          • Description: 
            • Enhance the Service Order API (TMF 641) to allow BSS/OSS the ability to flag services as part of a “group”.  Enhance the Service Inventory API (TMF 638) to allow BSS/OSS to retrieve Service Inventory by “group”.
          • Relevance:
          • Complexity: Easy
          • Prerequisites: Service Orchestrator (SO) and its external API, A&AI and its API to SO and its external API
          • Resources:
        • Update ServiceOrder to manage Service modification request UC
          • Description: 
            • This will allow BSS system to trigger service modification request. By modification we mean: characteristic value change, status change (other ?). Minimum could be to handle modification that can be managed in SO with a Delete Service and then Add service (this is a change up to nbi but remove/add down to nbi). This is not service order modification butt service modification on existing service instance in the inventory (new service order with action change)
            • Possibly related to CC VPN use case, explore other use cases
          • Relevance:
          • Complexity: Average to High depending on SO capability to handle service modification
          • Prerequisites: could require SO upgrade – Check if some use case can be handle by NBI only (triggering add/remove in SO)
          • Resources:
        • Update ServiceOrder to provide user and system workload information for both Infrastructure requested VNFs and Customer requested VNFs
          
          • Description: 
            • Requestors that create transaction requests on the ONAP Platform, have a need to effectively manage the requests they create.  The Requestor is the responsible owner for the transaction and thus, need visibility into the volumes of requests created by a requestor, in order to better balance the workload among their labor resources.

            • •BSS/OSS system will call the API providing one of the following options:
              1.Specific Service Request ID
              2.Specific User ID of the Requestor
              3.All Users

              ONAP will respond with what activity is happening, who is doing it, and how old is it.  Profile information can include Service Request Type, Creation/Completion Dates, and User ID of the Requestor.  This information may require a dip into VID
          • Relevance:
          • Complexity: Average
          • Prerequisites: Could implement in two phases, 1st phase implement request profile information that is currently available in the Service Orchestration (SO) API, while the 2nd phase add additional status information from VID
          • Resources:
      • Service Inventory
        
        • Add notification for serviceInventory API
          
          • Description: Allow BSS (or any other) system to receive service state update.
          • Relevance:
          • Complexity: Easy
          • Prerequisites: It requires to have a notification from AAI because NBI will not pool AAI
          • Resources:
        • Update Service Inventory to accommodate Service Chaining.
          
          • Description: 
            • Enhance the Service Order API (TMF 641) to allow BSS/OSS the ability to flag services as part of a “group”.  Enhance the Service Inventory API (TMF 638) to allow BSS/OSS to retrieve Service Inventory by “group”.
          • Relevance:
          • Complexity: Easy
          • Prerequisites: Service Orchestrator (SO) and its external API, A&AI and its API to SO and its external API
          • Resources:
        • Improve ServiceInventory API
          
          • Description:
            • As of now we retrieve very few information from AAI – Perhaps digging more in the instantiated VNF or VF could allow us to have more information as service state or serviceCharacteristic for example.
          • Relevance:
          • Complexity
          • Prerequisites: Need AAI expertise; Need enhancement to AAI UI to see more topology details across API
          • Resources:
      • Performance Management (specification focus) (stretch goal: implementation)
        • Provide performance data for both Infrastructure VNFs and Customer VNFs
          
          • Description:
            
            • Capacity planning engineers must be able to determine the performance and quantities of VNFs running on the network for planning purposes.  Performance Management data is required to develop Site Level Tenant and VNF & VM Forecasts that are the basis for Capacity Planning of the Network Infrastructure.  May also be used in support of customer self service to provide customers with performance information about their specific services and VNFs
            • BSS/OSS system will call the API providing starting and ending dates and times.  This API will be called either on-demand or on a regular timed basis.  ONAP will respond with performance management data from DMaaP and Performance Data Store, may be trended for forecasting process, and include specific metrics & KPIs for all existing VNFs/VMs in service.  May make use of TM Forum Performance Management API (TMF 628).
          • Relevance:
          • Complexity: Easy
          • Prerequisites: Could implement in two phases, 1st phase implement performance information that is currently available in the DMaaP API, while the 2nd phase enhance the DMaaP API with additional performance information.  Requires additional micro-service development for collecting information from DMaaP or data store to store and aggregate the information
