Methods for Defining a Network Service Descriptor (NSD) for a Network Service (NS), and Network Functions Virtualization (NFV) Orchestrator (NFVO) using said NSD

摘要

There are provided methods for defining a Network Service Descriptor (NSD) for a Network Service (NS), and Network Functions Virtualization (NFV) Orchestrator (NFVO) using said NSD. The NSD comprises zero, one or more of each of: a Virtualized Network Function (VNF) Descriptor (VNFD), a Physical Network Function (PNF) Descriptor (PNFD), a Network Service Descriptor (NSD), a Virtual Link (VL) Descriptor (VLD), and a VNF Forwarding Graph Descriptor (VNFFGD). One method comprising the step of defining at least one Connection Points (CP) Profile, wherein the CP Profile is referenced through a cpProfileId in a Network Forwarding Path Descriptor (NFPD) attribute of the VNFFGD, the CP Profile specifying a Connection Point Descriptor (CPD) or Service Access Point Descriptor (SAPD) for a given VnfProfile, PnfProfile or NsProfile.
