摘 要:传统高校极简网络方案通过集中认证的方式减少了接入汇聚设备的运维量,也解决了无线认证性能不足的问题,但同时其也暴露出了改造周期长、SuperVLAN 大二层部署下终端位置定位困难、哑终端部署复杂、无可视化管理界面等问题。软件定义网络(SDN)是一种指导未来网络发展的新架构,基于这种新的思想和方法论,学校打造出新一代网络平台,平台符合开放网络联盟ONF 所定义的SDN 网络架构,其包含网络基础设施层、控制层、网络应用层,并支持设备、控制、应用多层次开放,基于开放接口,用户可扩展网络应用,集成了计算/ 存储/ 网络于一体的IT 平台,充分展现了学校SDN 平台的平台开放性、设备虚拟化和网络智能化。

Abstract:The traditional minimalist network scheme in colleges and universities reduces the operation and maintenance of access convergence devices by centralized authentication,and also solves the problem of insufficient performance of wireless authentication. But at the same time,it also exposes the long transformation cycle,the difficulty of terminal location under the second-tier deployment of SuperVLAN,the complexity of dumb terminal deployment,and the lack of visual management interface. The software definition network (SDN)is a new architecture to guide future network development. Based on this new idea and methodology,the school has created a new generation of network platform. The platform conforms to the SDN network architecture defined by open network alliance(ONF),which includes network infrastructure layer,control layer,network application layer,and supports devices. Control and application are multi-level and open. Based on open interfaces,users can expand network applications,integrate computing/storage/network into an IT platform,fully demonstrate the openness of SDN platform,virtualization of equipment and network intelligence.
