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 invention discloses a forwarding service chain generation method and a network function virtualization orchestrator (NFVO). The method is applied to a network function virtualization (NFV) system. The NFV system comprises the network function virtualization orchestrator (NFVO), and at least one virtual function module. The virtual function module is deployed on at least one physical machine. The method comprises the steps that the NFVO obtains forwarding service chain generation information, wherein the forwarding service chain generation information comprises forwardingrelationship information, deployment relationship information and physical machine resource usage information; and a forwarding service chain is determined according to the forwarding service chain generation information, wherein the resource efficiency and the forwarding efficiency of the NFV system under the forwarding service chain satisfy a preset condition at the same time. Under the condition that a physical topology is not sensed by an application, the relatively high resource efficiency and forwarding efficiency can be obtained at the same time.

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...
