VerizonViswanath Kumar Skand PriyaAbility to model running instance of VNF / NS and associate it as part of NS Design.

ONAP should have the ability to model running instance of VNF / NS ( aka Resource for convenience ) and associate it as part of NS design.

During Deployment, Runtime should first discover existing instance of such resource. If such resource is not found, then based on NS design, the said resource has to be deployed in real-time and tied along with current NS. Decision to either stop deployment, rollback deployment, retry or create such resource will be part of design time decision.

During resource design, a choice has to be provided to specify whether running instance of this resource could be used as part of NS design ( as per above flow ).

All other LCM aspects of the said resource ( scaling / healing / discovery / termination ) has to be looked as well.

Note : One of the possible way is to perceive this running instance of VNF as a PNF ( aka black box ) in modelling by providing endpoint URL along with Payload. But this solution doesn't scale well and doesn't solve the problem holistically. Hence need a better solution.
