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 VES event to DCAE 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 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 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
