随着云计算技术在数据中心的大量普及和应用，云计算数据中心的规模在逐步扩大，服务器虚拟化和存储虚拟化等技术为云数据中心的计算能力和存储能力提供了保证。但是大量的云端应用汇集到云数据中心，使得传统的网络架构已经成为数据中心发展的瓶颈，新型的网络架构应用迫在眉睫。软件定义网络SDN（Software-Defined Network）技术，分离了网络的控制平面和数据平面，提供了可编程的网络环境，而OpenFlow技术作为SDN的原型实现方式，已经成为SDN最重要的一个开放协议标准。文章在分析SDN和Openflow技术的基础上，探讨如何在云数据中心环境中部署基于OpenFlow技术的网络架构。

With the increasing popularity of cloud computing technology and applications in the data center, cloud computing data center scale gradually expanded, server virtualization and storage virtualization technology for cloud computing power and storage capacity of data centers to provide a guarantee. But a large number of Cloud Applications gathered to cloud data center, making the traditional network architecture has become the bottleneck of the development of data centers, the application of new network architecture is imminent. Software-defined networking SDN (Software-Defined Network) technology, the separation of control plane and data plane network, provides a programmable network environment. As a prototype of SDN, the OpenFlow technology has become the most important open protocol of SDN. Based on the analysis of SDN and Openflow technology, this paper discusses how to deploy the network architecture based on OpenFlow technology in cloud data center environment.
