Method and system for realizing automatic update of virtual network function descriptor

Abstract

The present invention discloses a method and system for realizing automatic update of a virtual network function descriptor. The method comprises the steps that a network composer issues virtual network element operating performance check indexes to a virtual network element management device; a monitor reports current operating indexes of virtual network elements in real time to the virtual network element management device; the virtual network element management device judges if the current operating indexes are within preset permissible ranges of the check indexes; if not, the virtual network element management device reports a VNFD parameter updating request to the network composer; and the network composer automatically adjusts parameters in the VNFD according to the VNFD parameter updating request. According to the method and the system, virtual machine operating performance check indexes are issued by the network composer, a network function management device compares data reported by the monitor with the check indexes and intelligently applies for updating of parameters in the VNFD files, thus to realize optimized deployment of virtual networks and functions, and raise the use ratio of physical devices.

Description

technical field [0001] The invention relates to the technical field of intelligent pipelines, in particular to a method and system for realizing automatic updating of virtual network function description files. Background technique [0002] With the evolution of the network, the long purchase and deployment period of network equipment has seriously affected the development of new services, so the virtualization of network functions has become a hot research topic. At present, before the deployment of virtualized network equipment, it is necessary to verify all the manufacturer's software and general hardware in advance, and generate a virtual network function description file (VNFD), and perform automatic deployment of virtual network elements according to the parameters inside the file, which will bring two question: [0003] 1. The update of the virtual network function description file needs to be tested and verified jointly by equipment manufacturers and operators, whic...

AI Technical Summary

Problems solved by technology

[0003] 1. The update of the virtual network function description file requires the joint test and verification of equipment manufacturers and operators, which is costly and has a long update cycle

[0004] 2. The degree of cooperation between the parameters in the virtual network function description file and the hardware equipment cannot be automatically optimized, and the network efficiency is low

[0006] The existing technology mainly considers how to automatically deploy and configure virtual network devices based on VNFD, but does not consider the feedback and automatic update mechanism of the virtual network element deployment template after the general hardware is upgraded

In the existing technology, the upgrade of VNFD requires manual statistics of current operating indicators, and manual modification and verification of VNFD, which is very inefficient
