摘　　要：云计算的规模化发展对数据中心网络提出了新的挑战,要求应用SDN技术对数据中心网络进行虚拟化,以满足多租户环境下灵活调整的动态网络需求,overlay SDN是实现数据中心网络虚拟化的核心技术。研究了overlay SDN网络虚拟化的关键技术,提出了商业overlay SDN存在的兼容性问题,分析了overlay SDN实现异构兼容的主要方法,并提出了基于开源和白盒交换机实现异构兼容的overlay SDN架构。Cloud computing scale development provides a new chanllenge to data center network. Data center network is required virtulizing by SDN in order to meet flexible dynamic network requireement under multi-rent environment. SDN is the core technology to realize data center virtulization. The key technology of overlay SDN network virtualization was studied, the compatibility problems remained in commercial overlay SDN products was discussed, the main methods to solve this problem was analyzed, and finally an new overlay SDN architecture based on open source software and white-box switch that could work in heterogeneous hypervisors environment was proposed.
