摘　　要：目的:实现主备数据中心的大二层互通。方法:通过VxLAN技术构建的Overlay网络架构是在传统物理网络基础上实现了逻辑的二层网络。结果:使用EVPN技术构建的大二层网络,克服了传统数据中心网络二层问题,是网络支持云业务发展的理想选择,可为处于任何位置的业务服务带来最高的可扩展性、灵活性以及优化的性能。结论:网络虚拟化一直是云业务资源虚拟化的短板,VxLAN的网络架构提供了网络资源池化的最佳解决方式,是云网融合技术路线中网络部分的关键技术。Objective： To achieve the secondary interoperability of the main and backup data centers. Methods： The Overlay network architecture constructed by VxLAN technology is a logical two layer network based on the traditional physical network. Results： The use of EVPN technology to build the second layer network, which overcomes the disadvantages of traditional data center network of two layers, is an ideal choice for network support cloud business development, can be in any position of the business service brings the highest scalability and flexibility, and performance optimization. Conclusion： Network virtualization has been a short board business cloud resource virtualization, the network architecture of VxLAN provides the best solution to the pool of network resources, is the key technology of cloud network integration network technology in part of the route.
