Problems solved by technology

Since each network function is deployed in a physical device in NFV, once a physical device deploying any network function (such as a storage device or a switch on which a network function is deployed) fails, the location of the faulty physical device cannot be realized. The service function corresponding to the SFC causes service interruption

Abstract

The embodiment of the invention provides a function backup method and device, which relate to the technical field of communication and can still realize a corresponding business function even if a physical device deploying any network function fails. The method provided by the embodiment of the invention comprises steps: the evaluation value of each function node in a to-be-backed up service function chain is determined, and a to-be-backed up function node is determined according to the evaluation value of each function node, wherein each function node is deployed in one physical node respectively, and the evaluation value is used for evaluating the backup demand of the function node; and a to-be-backed up physical node is selected from a topology diagram of the to-be-backed up service function chain, wherein the to-be-backed up physical node is used to back up the network function of the to-be-backed up function node.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a function backup method and device. Background technique [0002] The purpose of network function virtualization (Network Function Virtualization, NFV) is to use virtualization technology to realize software and hardware decoupling, abstract network functions (firewall, content caching or multimedia transcoding, etc.) into independent applications, and deploy them to common standard servers , memory or switch. Service Function Chain (SFC) is a set of ordered network functions, which are connected through virtual links to realize various business functions. Among them, the business function is a function realized after planning data traffic passing through various network functions according to business requirements. [0003] Since NFV realizes the dynamic deployment of network functions, the creation of SFC is more convenient and quicker. Since each network function is...
