摘　　要：首先介绍基于SDN架构的软件定义安全SDS系统架构及VPN技术相关介绍,重点介绍了Overlay VPN技术。该技术能为中小企业提供低成本、高性能、易使用、安全的VPN服务。通过Overlay VPN预先在网络中部署中间转发节点v PE,SDS集中式控制器通过智能选路算法,为用户提供有保障的VPN服务。此外,还分析了Overlay VPN的架构、控制平面和数据平面的流程,并提出实现技术优化的方法和发展方向。First of all, this paper introduces the software defined security SDS system architecture based on the SDN architecture and the related introduction of VPN technology, and focuses on the Overlay VPN technology. This technology can provide low cost, high performance, easy to use and secure VPN services for small and medium enterprises. Through Overlay VPN, the intermediate forwarding node v PE is pre deployed in the network, and the SDS centralized controller provides the guaranteed VPN service for the users through the intelligent routing algorithm. In addition, the architecture of Overlay VPN, the process of control plane and data plane are analyzed, and the method and development direction of technology optimization are put forward.
