Problems solved by technology

However, since each application instance runs on a virtual network function (Virtual Network Function, VNF), each application instance cannot perceive the physical server deployment of the VNF, so it cannot select the optimal forwarding service chain

Abstract

The embodiment of the present invention discloses a method for generating a forwarding service chain and a network function virtualization orchestrator NFVO. The method is applied to a network function virtualization NFV system, and the NFV system includes a network function virtualization orchestrator NFVO and at least one A virtual function module, the virtual function module is deployed on at least one physical machine, and the method includes: the NFVO obtains forwarding service chain generation information, and the forwarding service chain generation information includes forwarding relationship information, deployment relationship information, and physical machine Resource usage information; and determining the forwarding service chain based on the forwarding service chain generation information, and the resource efficiency and forwarding efficiency of the NFV system under the forwarding service chain simultaneously satisfy preset conditions. In this way, the application can obtain better resource efficiency and forwarding efficiency at the same time without being aware of the physical topology.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for generating a service chain and a network function orchestrator NFVO. Background technique [0002] Network Function Virtualization (Network Function Virtualization, NFV) system decouples software and hardware and abstracts functions, so that network device functions no longer depend on dedicated hardware, resources can be fully and flexibly shared, and rapid development and deployment of new services are realized. Automated deployment, elastic scaling, fault isolation, and self-healing based on business needs. The basis of NFV technology includes cloud computing technology and virtualization technology. General-purpose computing, storage, network and other hardware devices can be decomposed into various virtual resources through virtualization technology for use by various upper-layer applications. [0003] After the telecom media business becomes NFV-based, each virtual n...
