移动铁通地市IP城域网互联解决方案

IP MAN interconnect of China Mobile Group Hunan Co.Ltd.Local Branch and China Tietong Group Co.Ltd.Hunan Local Branch

本文从分析湖南移动和湖南铁通现有互联方式存在的问题入手,结合双方网络结构现状,制定了湖南移动与湖南铁通地市IP城域网互联的原则:接入网就近接入的原则、满足上级单位管理要求的原则、满足安全与IP地址管理的原则、业务归属与上层流量疏导一致的原则。在此原则上,提出了通过QinQ技术,分别在接入层和汇聚层实现两层VLAN封装,以进行业务的区分和隔离。进而提出了铁通接入网在汇聚层分流上行,接入移动SR/BRAS;移动接入网在业务控制层分流上行,接入铁通地市核心路由器的解决方案。该方案的实施,扩大了湖南铁通有线宽带的覆盖范围,增强了湖南移动全业务竞争的能力。

Based on the analysis of the interconnection problems, the text combine both the current situation of the network, develope the principles of IP MAN interconnection by China Mobile Group Hunan Co. Ltd. Local Branch and China Tietong Group Co. Ltd. Hullan Local Branch, shuch as： the nearest access to the access network, meet the higher level unit management requirements, meet the security and IP address management, consistent with the business ownership and upper traffic. According to the principle, propose that achieve two VLAN encapsulation in the access layer and convergence layer by using QinQ technology, to achieve business division and segregation. And then propose the solution that TieTong access network split up in convergence layer, and access to Mobile SR/BRAS; Mobile access network split up in business controll layer, and access to TieTong city core router. The implementatioin of the solution will expand the converage of TieTong wired broadband, and enhance the whole business competition ability of HuNan Mobile.
