基于网络功能虚拟化的校园网接入及其负载均衡

Campus Network Access and Load-Balancing based on NFV

随着校园网接入方式由传统静态IP向宽带远程接入服务(BRAS)的迁移,通过实施基于MacVlan的网络功能虚拟化(NFV)技术应用,实现了在实验室环境下多PPPoE连接的校园网接入;并配合以策略路由技术,达成了多PPPoE出口的均衡负载。其不仅为师生提供了无缝的网络访问体验,同时还达到了带宽叠加的效果,有效提高了网络服务质量。

With the migration of campus network access mode from traditional static IP to broadband remote access service(BRAS),by applying MacVlan based network function virtualization technology,a multiple PPPoE connected campus network access is implemented in BRAS environment.Aided with policy-based routing technology,network load-balancing is implemented among these PPPoE exports.It not only provides users with a seamless network access exper ience,but also realized bandwidth super position and loadbalancing,which improved network service quality effectively.
