摘要
随着Internet的迅速发展和网络应用的急剧增加,移动设备和终端激增,服务器虚拟化以及云服务的出现推动着网络相关行业重新审视传统网络架构~（[1]）。常规的网络是分层结构,这种静态架构已不适应当今企业数据中心、校园和运营商网络环境的动态计算和存储需求~（[2]）。通过对校园网安全中存在的问题进行总结,分析SDN及相关技术工作原理,对SDN应用进行了分析和展望。
With the development of Internet,the rapid increase of network applications,the proliferation of mobile devices,and theemergence of virtualization and cloud services,the Internet industries have been pushed to reexamine the architecture of tradition-al network.The conventional network is a hierarchical structure that does not adapt to the dynamic computing and storage require-ments of today＇s enterprise data center,campus and operator network.Through summarizing the problems existing in campus net-work security,analyzing the working principles of SDN and related technologies,the application of SDN was prospected.
