Binhong MAO, Zhiming YANG. Research on NFV fault association and fault self-healing[J]. Telecommunications science, 2017, 33(11): 186-194. DOI: 10.11959/j.issn.1000-0801.2017261.
NFV implements the hardware and software decoupling of telecommunications network equipment
gets rid of the dependence on dedicated hardware equipment.NFV brings benefits such as resource sharing
automatic deployment
flexibility and other features
but it also brings some problems such as more fault points
difficult fault analysis and so on.It results in NFV network operation and maintenance more difficult.The NFV fault process and fault association were analyzed
and guidance for fault location processing in NFV was provided.At the same time
the VNF fault self-healing implementation scheme was given to realize the network element and service fault self-healing
and improve capability of automatic operation and maintenance.
