Use Cases

VNF Configuration (Ve-Vnfm-em)

As part of VNF instantiation/heal/scaleOut VNFM can Set VNF initial configuration using SOL002 VNF Configuration interface towards EM (ONAP).

SOL002 Adapter can convert this configuration to another protocol and ONAP Controller enables Operator configurability.

Benefits:

  • This use case enables VNFC level configuration.
  • This configuration interface only exists in SOL002 (compared to SOL003).

ONAP ETSI Alignment Copy

VNF LCM (Ve-Vnfm-em)

SOL002 VNF LCM interface use can be divided to 2 separate sub-use cases:

  1. LCM Action execution
  2. LCM Notification Subscribing/Consuming

ONAP ETSI Alignment SOL002 VNF LCM ONAP ETSI Alignment SOL002 VNF LCM Notifications

VNF Indicator Interface (Ve-Vnfm-em)


ETSI-Alignment SOL002 Adapter Use Cases

  • VNF LCM (Ve-Vnfm-em). ONAP as EM role.
  • Application configuration 
    • Option 1: VNFM initiated: Application configuration (Ve-Vnfm-em). ONAP as EM role.
    • Option 2: Through LCM notifications subscribed with VNF LCM interface, SOL002 Adapter can execute wanted configuration.
  • Enable VNFM to subscribe Indicator notifications through VND indicator interface.
  • Security between Adapter and VNFM (not sol002 adapter alone, but same code/mechanism should be used as other adapters)
  • Application configuration (Ve-Vnfm-vnf). ONAP as VNFM role. (Stretch goal)

Feature Descriptions

Feature

Description

SOL002 Adapter to execute VNF LCM operations towards VNFM (Ve-Vnfm-em)
SOL002 Adapter to subscribe VNF LCM notifications from VNFM to enable ONAP operations (VNF configuration, CLoseLoop termination etc.)
SOL002 Adapter application configuration (Ve-Vnfm-em) by VNFM

SOL002 Adapter exposes configuration endpoint for external VNFM:

  • SOL002 Adapter performs EM role (Ve-Vnfm-em)
  • VNFM calls SOL002 Adapter configuration API
  • SOL002 Adapter translates the configuration request into APPC/GNFC - specific API-call
  • APPC/GNFC configures specific VNF or VNFC accordingly
SOL002 Adapter enables VNFM to subscribe to VNF indicator notifications by VNFM and send indicator notifications to VNFM (Ve-Vnfm-em)


SOL002 Adapter application configuration (Ve-Vnfm-vnf)
(Stretch goal)

SOL002 Adapter exposes West-bound interface to any ETSI-aligned VNF.

SOL002 Adapter utilizes configuration call towards ETSI-aligned VNF:

  • SOL002 Adapter performs VNFM role (Ve-Vnfm-vnf)
  • SOL002 Adapter calls VNF's SOL002 configuration API
