A virtual network function vnf fault handling method and vnf management equipment

Abstract

The invention discloses a virtual network function VNF fault processing method, which comprises the steps of arranging a memory block in an VNF of an NFV system in advance, disconnecting a management network and a service network of the VNF when confirming that the VNF fails, connecting a standby VNF, which is in mutual backup relation with the VNF in the NFV system, to the management network, sending description information and memory data to the standby VNF after the description information and the memory data of the memory block corresponding to the VNF are queried in a stored synchronization relation table, and finally starting a service network of the standby VNF after the standby VNF updates memory according to the description information and the memory data. Therefore, the master / standby switching of the VNF can be achieved conveniently and effectively when an VNF fault occurs in the NFV network, system resources required in fault switching implementation is reduced as much as possible, and the overall stability of the network is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a VNF fault handling method. The present invention also relates to a VNF management device. Background technique [0002] NFV (Network Function Virtualization, Network Function Virtualization) is a software processing technology that uses general-purpose hardware and virtualization technology to carry other functions, aiming to reduce the cost of expensive network equipment. Through the decoupling of software and hardware and functional abstraction, NFV makes network device functions no longer dependent on dedicated hardware, and resources can be fully and flexibly shared to achieve rapid development and deployment of new services, and perform automatic deployment, elastic scaling, and fault isolation based on actual business needs and self-healing etc. [0003] With the rise of virtualization technology and the maturity of NFV technology, many network equipment vendors ...

Problems solved by technology

At the same time, both the active VNF and the standby VNF must be kept in the working state at the same time, so that the subsequent real-time backup of the session based on the business and the switching of the VNF in the event of a failure. During this process, the active VNF and the standby VNF are both in the active state. Personnel need to implement operations such as control and management of active and standby devices, and real-time synchronization of business sessions in the VNF. The network design and implementation mechanism are very complicated.

In addition, since both the active VNF and the standby VNF are active, the backup VNF will also occupy IP resources, and the real-time synchronization of control information and business information will consume additional link interface resources, resulting in half the effort
