摘　　要：软件定义网络具有可编程、灵活、可扩展的优点,但软件定义网络与传统网络并不兼容。为解决软件定义网络与传统网络互联互通问题,设计一种混合软件定义网络的控制器架构,该架构集成软件定义网络和传统网络的控制平面,为混合网络构建一个集中管理平台。基于此架构实现混合软件定义网络控制器,该控制器包含POX控制器和路由服务器两个主要组件。实验结果表明,该架构实现传统网络与软件定义网络的通信,具有兼容传统网络和可靠性高的优势。Software defined networks(SDN)have the advantages in programmability,flexibility and scalability.But they are not compatible with traditional networks.To address the interoperability between the SDN and traditional networks,a controller architecture on hybrid software defined networks is proposed.This architecture integrates SDN control plane with traditional networks control plane and builds a centralized management platform for hybrid networks.A hybrid SDN controller is implemented based on this architecture.The controller consists of two main components,a POX controller and a routing server.The experimental results show that this architecture enables traditional networks to communicate with the SDN and has the advantage of compatibility with traditional networks and high reliability.
