摘　　要：起源于Stanford大学的OpenFlow技术为互联网的创新带来了一场革命,OpenFlow技术将传统网络中的控制和转发功能分离,采用了集中式的控制方式和基于流的转发机制,使得物理设备在部署之后仍然可以通过编程改变其工作方式,亦即"软件定义网络"。由于OpenFlow技术的这些优点,它被认为是未来互联网技术的有力竞争者。路由功能作为网络的一项基础功能,无疑具有重要的作用。而OpenFlow到目前为止还没有一个完整的路由解决方案,使得在OpenFlow网络中,子网的部署、管理极为复杂。本文正是看到了这一空白,提出了一种路由解决方案,并且初步实现了原型系统,进行了部署测试。The OpenFlow technology originated from Stanford University brings a revolution to the internet innovations.OpenFlow splits the functionality of control and forwarding,and employs centralized hierarchy as well as flow-based forwarding mechanisms,compared to traditional networks.These innovations make network administrators to be able to change functionalities even after the physical devices have already been deployed（also known as ＂Software Defined Network＂）.Since OpenFlow has so many advantages over traditional network,it is known as the main competitor of future internet.Routing is recognized as an essential functionality of a network,however traditional fully-distributed routing mechanism doesn＇t properly fit in an OpenFlow network because of the change in network architecture.Thus after some investigation and research,we design and implement a routing framework that fits in the current environment in which OpenFlow network co-exists with traditional network.
