摘　　要：随着IP网络的不断发展,越来越多的人开始关注并选择在这个互联网时代通过各种渠道获取自己想要得到的信息资源。从2015年起,IP网络逐渐成为人们使用的主要媒介。以段路由(Segment Routing,SR)作为研究对象,分析了其发展现状及趋势。SR是一种基于节点转发的新型网络结构,它将传统的骨干网和接入层进行分离,使得每一个节点都可以独立完成数据传输任务。同时,为了提高传输效率、降低成本、减少对用户终端设备的依赖性,骨干网采用了扁平化设计,即将所有的设备都集中放置于同一个空间内,这样就能够有效避免设备之间相互影响,也便于管理维护。With the continuous development of IP network,more and more people begin to pay attention to and choose to obtain the information resources they want through various channels in this Internet era.Since 2015,IP network has gradually become the main medium for people to use.This paper takes Segment Routing(SR)as the research object,and analyzes its development status and trend.SR is a new network structure based on node forwarding,which separates the traditional backbone network from the access layer,so that each node can independently complete the data transmission task.At the same time,in order to improve transmission efficiency,reduce costs and dependence on user terminal equipment,the backbone network adopts a flat design,that is,all devices are centralized in the same space,which can effectively avoid mutual influence between devices and facilitate management and maintenance.
