【摘要】To solve the problem that under the current ETSI NFV VNF frame the VNF update operations would result in service interruption of traffic, the VM updating strategy with lower level of granularity as compared with VNF is proposed. With the help of redundancy mechanism among VNF internal components, an enhanced NFV workflow for interaction in among NFVO, VNFM and VNF is described, which allows VNF VM updating determined by VNFM alone or VNF alone, or through negotiation of VNFM and VNF, thus realizing the VF updating relating to VNF internal components in batches or in sequence, and that the NFV fame could smoothly finish VNF updating operations, such as capacity scaling-up, and upgrading, etc.. And all this could raise the availability and practicability of the virtualized communication network elements.%针对当前ETSI NFV框架下VNF更新操作时会引起业务中断的问题，给出了比VNF粒度更小的VM更新策略。借助VNF内部组件的冗余机制等，提出了增强NFVO、VNFM和VNF之间交互的流程和方法，由VNFM单独确定、VNF单独确定或由VNFM和VNF协商确定VNF VM变更策略，通过分批次、按顺序实现VNF内部组件相关VM的变更，使得NFV框架能够在VNF不中断业务的前提下平滑完成VNF的如扩容、升级等涉及VM
