Minutes: Toshiaki: Want to ensure hardware errors are managed well at orchestration, as they are not attended at MANO level * Thought is they should be in closed loop at a lower layer * Manual healing/scaling is important. * System integrator's do this manually at service layer. Generally EMS does this in open loop fashion * In some cases EMS cannot provide enough resources to applications and it should also be coordinated by VNFM * Question is when does closed loop take over * While EMS might try to restart the application while VIM might take closed loop action and EMS would fail to complete * we need to ensure each VNF is compatible for set of established closed loops policies * would require to propagate metadata to EMS & service layer about closed loop How can we overcome current functionality of SOL003 standard in coordination with VIM/VNFM for closed loop purposes: * SOL003 defines integration between NFVO and VNFM. Designed as per ETSI MANO solution standards * If we make changes like healing a VNF, they should be propagated to orchestrator, however SOL003 doesnt support these interactions * SOL003 does not support VNF migration as its considered out of MANO scope * Need to find a way to include these use cases as it might cause loss of functionality and ensure topological information is propogated * Would be good to list out the use cases of interest and see how these can be addressed * Some of the solutions deduce and establish few specific cases that could be done by closed loop ONS-EU Conference: * Talk on self-heling/resiliency by Tomi & Sunku got accepted * Tomo/Yuki/Toshiaki are joining ONS-EU * would be good to have unconference session so multiple demos could be shared. * Looking to update unconference sessions for CLA WG Next Time agenda: * SOL003 standards - check with Al Morton<https://wiki.opnfv.org/display/~acm> * How can we align with CVP Details captured here: https://wiki.opnfv.org/display/CLAWG/July+18+2019 Thanks, Sunku Ranganath
