A physical network function pnf migration method and related equipment

Abstract

The embodiment of the present invention discloses a physical network function PNF migration method and related equipment. The method is applied to a network function virtualization NFV system, and the NFV system includes a network function virtualization orchestrator NFVO. The method includes: the The NFVO receives the trigger migration message sent by the network management system OSS, which is used to trigger the NFVO to migrate the function of the PNF node to the NFV system, and the NSD has a virtual network resource description that replaces the PNF; the NFV system deletes the After the PNF resource is configured, the NFVO instantiates the virtual network resource of the PNF based on the PNFD identifier, the PNF node instantiation identifier and the virtual network resource description. Therefore, the PNF function can be quickly migrated to the VNF system, and the time for migrating from the PNF to the VNF can be shortened.

Description

technical field [0001] The invention relates to the communication field, in particular to a physical network function (PNF) migration method and related equipment. Background technique [0002] Network Function Virtualization (Network Function Virtualization, NFV) mainly sets industry-wide standards for network function virtualization. [0003] In NFV, NFV-MANO (NFV Management and Orchestration) mainly implements the management and orchestration functions of the entire NFV. In NFV-MANO, different functions of NVF are managed by different functional modules. For example, NFVO is an important module in NFV-MANO, which can be used to decompose each network service description (Network Service Descriptor, NSD). To meet the requirements of the virtualized network function (Virtualized Network Function, VNF), cooperate with the virtualized network function manager (VNF Manager, VNFM) to realize the deployment of the VNF. VNFM is mainly used to decompose the demand for virtual re...

Problems solved by technology

[0004] At present, NFV-MANO does not manage the traditional physical network function (PNF), which belongs to the external docking relationship with the traditional physical network function (PNF). When the PNF node in Network Service fails or the PNF node needs to be migrated to cloud resources, then Operators need to redesign the VNFD that replaces the PNF, and at the same time need to redesign a new NSD, which takes a long time to deploy, resulting in long service interruptions
