SDNC APIs

SDNC APIs

  •  

    • DMAAP listener : used to listen for event notifications from DMaaP. 

      •   For Amsterdam release, the vCPE use case posts a notification to DMAAP that alerts SDNC when a BRG receives an IP from DHCP.  The DMaap listener then will invoke the GENERIC-RESOURCE-API to set up a WAN connection for that BRG.

      • For Beijing release, SDN-C will also subscribe to an additional topic on DMaaP to receive LCM events, which will in turn invoke the LCM API.

  •  

    • New for Beijing release:

      • LCM (Lifecycle Management) API - used in Change Management and Manual Scale Out functional requirements to allow SDNC to process lifecycle events for L1-L3 VNFs.

      • The same rest api northbound is used in both SDNC (L1-L3) and APPC (L4-L7) - auto-generated from LCM-API.yang but the "action" parameters that can be sent via that API - some dont work on SDNC like start/stop/restart/evacuate - others like ModifyConfig will work on SDNC

      • See APP-C LCM API guide for additional information



  • Outgoing API:

    • A&AI : SDNC will read/write objects to A&AI.  The base aaa-service class is capable of reading/writing any object defined in A&AI XSD schema.  The directed graphs for the use cases will drive which specific objects are read/written.

    • External SDNC controllers : SDNC will interface to external SDNC controllers to create underlay/overlay networks (for VoLTE).  These external controllers expose a RESTCONF interface, which SDNC will invoke using its restapi-call-node interface.
