45、gement of an NS. ETSI ETSI GS NFV-IFA 014 V3.1.1 (2018-08) 9 An NS is a composition of Network Functions (NF) arranged as a set of functions with unspecified connectivity between them or according to one or more forwarding graphs. As illustrated in figure 4.1-1, the description of a NS as used by th

46、e NFV Management and Orchestration (MANO) functions to deploy an NS instance includes or references the descriptors of its constituent objects: Zero, one or more Virtualised Network Function Descriptors (VNFD); Zero, one or more Physical Network Function Descriptors (PNFD) used by the NFVO to determ

47、ine how to connect PNFs to VLs; Zero, one or more nested NSD; NOTE 1: The information contained within the PNFD is limited to the description of the connectivity requirements to integrate PNFs in an NS. NOTE 2: An NSD references at least either one VNFD or one nested NSD. Zero, one or more Virtual L

48、ink Descriptors (VLD) used by the NFVO to deploy Virtual Links (VL); and Zero, one or more VNF Forwarding Graph Descriptors (VNFFGD). A VNF Forwarding Graph Descriptor (VNFFGD) describes a topology of the NS or a portion of the NS, by referencing a pool of connection points and service access points

49、, the descriptors of its constituent VNFs, PNFs and of the VLs that connect them. It may also contain one or more Network Forwarding Path (NFP) descriptors. NOTE 3: Different VNFFGDs can be contained in a given NSD. Each VNFFGD uses subsets of the lists of VLDs, VNFDs and PNFDs included in the NSD. NOTE 4: For a given NS different VNFFGs can result in packets/frames traversing identical sequences of (V)NFs, depending on the NFP descriptors included in the VNFFGDs. NOTE 5: In a given VNFFG the connectivity topology represents how the (V)NFs among
