基于OpenFlow的数据流管控系统的研究与实现

随着网络技术的不断发展，在现有的网络设备及协议基础之上，对已有网络进行创新性试验变得越来越困难。OpenFlow是为支持网络创新究而提出的新型网络技术，它的出现为部署一个大规模的、完全可控、可定制的实验网络平台提供了可能。本文旨在基于OpenFlow设计实现一个数据流管控系统，其主要思想是利用OpenFlow技术实现控制与转发的分离，通过集中控制的方式，实现对全网数据流的管控，提高OpenFlow网络的安全性。

A Data Flow Management System Based on OpenFlow

As the development of the network technology, it is dififcult to test innovative network in the existing network equipment and protocols. OpenFlow is a new technology for network to support innovative research, It provides the possibility for a large-scale, controllable, customizable experiment network platform. This paper expounds the design and implementation of a data stream management system based on OpenFlow, the main idea of the this system is to separate the control and forwarding, through a centralized conifguration management, realize the control of the entire network data lfow, therefore, improve OpenFlow network security.
