基于SR的IPv6过渡技术设计与实现

Design and Implementation of IPv6 Transition Technology based on SR

分段路由(Segment Routin,SR)作为一种新型MPLS技术,能够与软件定义网络(Software Defined Network,SDN)完美结合,利用SDN控制器作为SR的控制平面,取消MPLS网络的复杂控制协议。新一代网络会采用软件定义网络和分段路由技术,实现网络的可编程控制和基于标签的转发。随着IPv6技术的逐步应用,IPv6子网需要穿越新一代网络。因此,提出了一种基于软件定义网络和分段路由技术的IPv6过渡技术解决方案,利用SDN控制器完成IPv6子网之间的路由同步和SR路径建立,采用SR技术完成IPv6数据转发。

As a new type of MPLS technology,SR(Segment Routing)can be perfectly combined with SDN(Software Defined Network).By using the SDN controller as the control plane of SR,the complex control protocol of MPLS network is eliminated.The new generation network will use SDN and SR technology to realize the programmable control and label-based forwarding of the network.With the gradual application of IPv6 technology,IPv6 subnets need to traverse a new generation network.Therefore,an IPv6 transition technology solution based on software-defined networking and segment routing technology is proposed,which uses SDN controller to complete route synchronization and SR path establishment between IPv6 subnets,and adopts SR technology to complete IPv6 data forwarding.
