Problems solved by technology

[0005] In the existing NFV system, each virtual device is centrally deployed in a data center (Data Center, DC). For users in areas far away from the DC, the data transmission of network services must pass through many data forwarding devices, and the data transmission The longer the distance, the higher the delay in data transmission

Abstract

The application discloses a method and system for deploying a VNF, and belongs to the technical field of the virtual network. The method comprises the following steps: a NFV system is deployed in distributed DC network architecture, wherein the NFV system comprises NFVO, VNFM and VIM, the NFVO can acquire a NS deployment request, and determines the related target VNF, a target DC satisfying the deployment demand of the VNF can be selected according to DC selection information added in the VNFD, and then the target DC can execute the deployment processing of the target VNF. By adopting the method disclosed by the application, the data transmission delay of the network service can be reduced, the packet loss is reduced, and then the quality of service can be improved.

Description

technical field [0001] The present application relates to the field of virtual network technology, and in particular to a method and system for deploying VNF. Background technique [0002] The existing NFV system includes an NFV management and orchestration system (NFV Management and Orchestration, NFV MANO), an NFV infrastructure layer (NFV Infrastructure, NFVI), multiple virtual network functions (Virtual Network Function, VNF), and multiple network element management (Element Management, EM), network service, VNF and infrastructure description (Network Service, VNF and Infrastructure Description), and business support management system (Operation-Support System / Business Support System, OSS / BSS). Wherein, the NFV management and orchestration system includes an NFV orchestrator (NFV Orchestrator, NFVO), one or more VNFMs (VNFManager, VNFM) and a virtualized infrastructure manager (Virtualized Infrastructure Manager, VIM). [0003] For each network service, the server can d...
