摘　　要：混合云是在企业自有IT基础上构建与云端网络互联的混合IT基础架构。对运营商来讲,为企业提供混合云需要解决多租户网络虚拟化的问题,并提供虚拟网络间的弹性互联。文章介绍混合云的网络虚拟化架构,提出虚拟化组件的性能优化方法以及虚拟化网络的动态可扩展设计,为运营商运营混合云服务提供理论指导和实践支持。Hybrid cloud constructs the hybrid IT infrastructure by connecting the enterprise＇s on-premises IT and cloud networks. For operators, providing hybrid cloud service needs to solve the problem of network virtualization and provide the flexibility interconnection among virtual networks. This paper introduces the network virtualization architecture of hybrid cloud, then proposes the performance optimization methods of virtualization components and the dynamic scalability design of virtual networks, which can provide theoretical guidance and practice support for operators to operate hybrid cloud service.

关 键 词：混合云 网络虚拟化架构 性能优化 动态扩展
