基于VPP的虚拟路由器数据平面加速方法

摘要

This paper proposes a method to accelerate the virtual router's data plan by VPP.This method separates the virtual router into control plan and data plan,then moves the data plane's transform work to the VPP running in Linux userspace and alters the VPP's route table by listening to the control plan info.In this way,it could eliminate the bottleneck of the traditional virtual route's rate of transform packets which make it possible to replace the network device with standard x86 platform server.It can promote the network function virtualization in some way and make the network resource more flexible and easier to be managed.%本文提出了一种使用VPP对虚拟路由器数据平面加速的方法,此方法将数据平面与控制平面分开,然后将数据平面的转发工作转移到Linux用户空间下的VPP上面,并通过监听控制平面信息,实现数据平面路由表的更新.通过此种方法,可消除虚拟路由器在报文转发速率上的瓶颈,使得使用标准x86平台服务器替代专用网络设备成为可能,从一定程度上促进了网络功能虚拟化的发展,使得网络资源更加具有弹性,易于管理.
