摘要
随着无线宽带接入业务需求的增多,中国移动公司开始着手铺设有线接入网络,由CMNET城域网承载有线接入网,需要接入的业务主要有PON设备、IDC机房接入、WLAN热点以及个人宽带用户,为适应多业务承载需求,需要从带宽能力、数据配置、接入技术和网络架构多方面进行网络优化升级工作。随着城域传送网业务IP化趋势深入以及PTN网络加紧建设,CMNET城域网需要与原有传送网络进行有机融合。笔者探讨分析了几种可行的网架结构,给出了自己的建议。
With the increasing demand for wireless broadband access business,China Mobile began laying cable access network,carrying cable access network by the CMNET network.The main businesses that need access are PON devices,IDC room access,WLAN hotspots,and personal broadband users.In order to adapt to multi-business carrying demand,it is necessary to optimize and upgrade the network from the bandwidth capacity,data configuration,access technology and network architecture.With the trend of metro traffic network IP and the construction of PTN network,CMNET metropolitan area network needs to be fused with the original transport network.In this paper,several feasible grid structures are discussed and some suggestions are given.
