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 central-ized 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 de-vices 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. Rout-ing 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.
