NFV故障关联及故障自愈方案研究

利用NFV实现电信网络设备软硬件解耦，摆脱了对专用硬件设备的依赖，并能利用NFV资源共享、自动部署、弹性伸缩等特性，但同时也带来了故障点多、故障定位分析困难等问题，导致NFV网络的运营维护难度增加。分析了NFV故障处理的流程及故障关联方案，为NFV场景下的故障定位处理提供指引。同时给出了VNF故障自愈实现方案，利用VNF特性，实现网元及业务自愈，提升自动化运维能力。

Research on NFV fault association and fault self-healing

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.
