SOL002 Adapter exposes VNF configuration endpoint for external VNFM:

• SOL002 Adapter performs EM role (Ve-Vnfm-em)
• VNFM calls SOL002 Adapter VNF configuration interface
• SOL002 Adapter translates the configuration request into APPC/CDS/GNFC - specific API-call
• APPC/CDS/GNFC configures specific VNF or VNFC accordingly

SOL002 Adapter utilizes VNFM exposed SOL002 VNF LCM interface:

• ONAP DCAE/Policy executes Close Loop based on VNF or VNFC level events
• ONAP Controller or SOL002 Adapter directly can react to Policy trigger as Policy actor to perform LCM operation for VNF
• SOL002 Adapter is used to translate LCM action to SOL002 interface format towards external VNFM
• External VNFM performs VNF resource changes (VNFC or VNF level)

SOL002 Adapter utilizes VNFM exposed SOL002 VNF LCM interface to subscribe LCM Notifications:

• SOL002 Adapter subscribes LCM notifications at startup (e.g. listen all notifications)
• SOL002 Adapter receives LCM notification and emits event to DMaaP e.g. for Policy to consume
• User should model action Policy to react to these events on ONAP side
• Based on modeled action some operation can be done. E.g. with ONAP Controller to configure VNF. Clean Close loop etc.

SOL002 Adapter exposes VNF Indicator subscription endpoint and sends Indicator notifications to external VNFM:

• VNFM calls SOL002 Adapter to subscribe VNF Indicator notifications
• SOL002 Adapter stores subscriptions according to standard
• SOL002 Adapter starts to listen DMaaP events based on subscription
• SOL002 Adapter consumes any matching events and translates events to SOL002 Indicator notification and sends to subscriber
