Method of upgrading network function virtualization application as well as method and device for forwarding business

Abstract

An embodiment of the invention provides a method of upgrading a network function virtualization application as well as a method and a device for forwarding business. The method of upgrading the network function virtualization application comprises the following steps that a virtualized infrastructure manager VIM creates network resources according to an upgrading plan of an NFV (Network Function Virtualization) application; the VIM creates a virtual machine of a new edition of virtual network function VNF according to the upgrading plan; the VIM configures the virtual machine to a test network according to the network resources; the VIM carries out upgrading configuration on the virtual machine according to an upgrading configuration script, so that the new edition of VNF is obtained; and after an NFV orchestrator NFVO determines that the function test of the new edition of VNF at the test network is successful, an old edition of VNF is switched to the new edition of VNF. In the embodiment of the invention, through defining an automated process for upgrading the network function virtualization application and the upgrading steps, the automated process for upgrading the network function virtualization application can be implemented.

Description

technical field [0001] The present invention relates to the field of network function virtualization, and more specifically, to a method for upgrading a network function virtualization NFV application, a method and a device for forwarding services. Background technique [0002] Network Functions Virtualization (Network Functions Virtualization, NFV) aims to adopt the virtualization technology in the evolving information technology (Information Technology, IT) field to unify a large number of network device types into high-capacity servers, switches and storage devices that meet industry standards It can be implemented on the Internet, thereby changing the way network operators build and operate networks and network services (Network Service, NS). NFV changes the architecture of the network by implementing network functions through software that can run on a series of industry-standard server hardware, and because these software can be dynamically moved or instantiated in dif...

Problems solved by technology

[0004] When an application in NFV needs to be upgraded, it is usually impossible to flexibly arrange the upgrade sequence and process. The upgrade process is done manually and lacks an automated process.
