40、 Service Descriptions The Network Service Descriptor (NSD) is a deployment template which consists of information used by the NFV Orchestrator (NFVO) for life cycle management of an NS. An NS is a composition of Network Functions (NF) arranged as a set of functions with unspecified connectivity betw
41、een them or according to one or more forwarding graphs. As illustrated in figure 4.1-1, the description of a NS as used by the 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 N
