摘　　要：分段路由SR技术是一种源路由机制,继承MPLS技术的数据转发方式并在控制平面进行优化。使用IGP替代RSVP/LDP进行标签的分发,同时利用了IGP FRR实现了节点间的可靠保护,路由域边界节点的保护以及路径负载分担保护。支持绑定标签,可以很好的支持异构网络的互通。SR与SDN控制器共同作用,可以实现灵活的业务调度和动态保护。本文对SR技术原理和实现方式进行论述并基于PTN设备验证SR技术及其应用场景可行性。研究结果表明SR技术可以应用在PTN组网中并能提高网络性能及系统灵活性。Segment routing(SR) is a source routing mechanism that inherits the data forwarding mode of MPLS technology and optimizes it in the control plane. IGP is used instead of RSVP/LDP for label distribution. At the same time, IGP FRR is used to achieve reliable protection between nodes, and protection of routing domain boundary nodes and path load sharing protection. Supports binding tags, which can well support the interworking of heterogeneous networks. The SR works in conjunction with the SDN controller to implement flexible service scheduling and dynamic protection. This paper discusses the principle and implementation of SR technology and simulates SR technology based on PTN equipment and its application scenarios. The research results show that SR technology can smoothly transition traditional networking technology and improve system flexibility in PTN networking.
