摘　　要：基于解决省内城域网间横穿流量的问题,综合论证虚拟下一跳及业务控制层收取全网BGP路由2种技术解决方案,对不同场景下的推荐方案给出相应的建议。以广东部分试点为例进行了改造效益分析,并给出了广东及全国推广的投资效益节省量化数据,研究成果可优化中国联通本地城域网络的结构配置,大大节约数据设备投资以及传输资源,提升用户使用感受,提升中国联通的网络投资效益。In order to solve the problem of the flow between the core router in the provincial MAN,two technical solutions of the service control layer equipment collecting the BGP routing of the whole network and the virtual next hop are demonstrated. Recommendations for different scenarios are given. Taking some pilot projects in Guangdong as an example,the benefit analysis of transformation is carried out,and the investment benefits and investment data of Guangdong and the whole country are given.The research results can optimize the structure and configuration of LAN,greatly save the investment of the data equipment and the transmission of resources,improve user experience and the network investment efficiency of China Unicom.
