5. Design-time vs. Runtime MANO constructs
Descriptors associated to
Network Service (NS)
Virtual Network Function (VNF)
Virtual Links (VL)
VNF Forwarding Graph (VNFFG)
Physical Network Function (PNF)
Static & Runtime
Design = Descriptor (e.g. VNFD)
Runtime = Record (e.g. VNFR)
Records stores the actual state of MANO constructs

8. MultiSDO Information Modelling Workshop (Louisville, Colorado USA, January 13-14, 2016)
Participating organizations named in alphabetical order: 3GPP, ATIS, Broadband Forum, DMTF, ETSI NFV, IETF, ITU-T SG15, MEF, OASIS/TOSCA, Open Cloud Connect, ONF, OpenDaylight, OPNFV and TM-Forum
Useful information sharing across organizations concerning IM/DM affecting/affected by NFV,
Collected a set of issues affecting “the ideal” IM/DM work outcome for NFV, agreed to meet again and share information on the progress of issue discussion.
Presentations here.
