基于网络虚拟化的高可靠校园网的设计与实现

Design and Implementation of High Reliable Campus Network Based on Network Virtualization

在校园网规划时,为保障和提高网络的可靠性同时减少单点网络故障,通常会采用在关键的环节进行冗余设计。传统的网络主要采取MSTP+VRRP技术,实现路由冗余备份和负载均衡以提高网络的可靠性,但由于组网的设备间均需同时运行MSTP协议,管理和维护较为复杂,且VRRP网络中采用主备架构,存在一定的资源浪费。针对传统方案的不足,以中山大学南方学院校园网为例,采用网络虚拟化技术,使管理与控制分离,通过扁平化高性能管理实现高可靠网络。测试结果表明,网络虚拟化技术在网络可靠性方面取得良好效果,达到了预期目标。

Traditional network mainly adopts MSTP+VRRP technology,realizing redundant backup of route and ensuring the reliability of network.But it was very inconvenient for equipment management and maintenance and causing a waste of resources.In view of the shortcomings of traditional schemes,this paper takes Nanfang College of Sun-Yat-Sen University campus network as example,realizes high reliability campus network by adopting network virtualization technology and flat management.At last,the experiment shows that the network virtualization technology is more reliable in the network and achieves the expected goal.
