摘　　要：运营商正在通过引入IT基因来重构网络,以应对互联网企业的竞争。其中核心网的重构将是整网重构的切入点,而网络功能虚拟化(NFV)则是实现重构的重要手段。本文首先分析了核心网基于NFV进行重构的背景,然后介绍了核心网重构的目标架构和虚拟化相关的关键技术,最后探讨了核心网重构的相关策略。Operators are re-architecting the network by introducing IT genes to confront the competition from Internet companies. Re-architecting core network is the breakthrough point of the whole network’s process, and NFV (Network Functions Virtualization) is the important means to realize it. The background of rearchitecting core network based on NFV is analyzed fi rstly. The target architecture of core network and the related key technologies are introduced. Finally, the relevant strategies to re-architect core network are discussed.
