摘　　要：为解决传统网络功能虚拟化(network functions virtualization,NFV)系统由于其数据中心的独立自治性,难以实现跨数据中心的网络功能连接管理的问题,提出一种跨数据中心的网络功能连接管理机制NFVMP。设计子链生成算法,根据全局服务功能链生成所有数据中心的子链;设计分布式连接方案,在每一个数据中心内部利用分发器和转发器构建与其它子链之间的连接关系;设计一个增量更新的方法快速进行跨数据中心策略更新。在实验中实现一个原型系统对NFVMP的性能进行验证,其结果表明,NFVMP可以正确快速地跨数据中心进行服务功能链部署。与最佳性能结果相比,NFVMP只带来了几乎可以忽略的系统性能下降。To solve the problem that the traditional network functions virtualization(NFV)system is difficult to achieve cross-data center network function connection management due to the independent autonomy of its data center,a cross-data center network function connection management mechanism was proposed,namely NFVMP.The sub-chain generation algorithm was designed to generate the sub-chains of all data centers according to the global service function chain.A distributed connection scheme was designed,distributors and transponders were used in each data center to build the connection relationship with other sub-chains.An incremental update method was designed to quickly update cross-data center strategy.In the experiment,a prototype system was implemented to verify the performance of NFVMP.The results show that NFVMP can correctly and quickly deploy service function chains across data centers.Compared with the best performance results,NFVMP only brings almost negligible system performance degradation.
