摘要
IP城域网作为多种业务承载的平台, 建网的目的是立足现有业务,使IP城域网高度可控、易管理和可持续发展。目前IP城域网暴露出一些问题。从技术原理上讲,采用VLAN TAG进行交换的V-SWITCH技术能够解决IP城域网面临的实际问题。从城域网的架构和业务分析入手,根据V- SWITCH技术原理和优势,提出了采用V- SWITCH技术实现同城互联业务的方案以及BRAS侧挂于SR的组网模型。
As a multi-services platform, IP MAN should be highly controllable, easily management and sustainable development. Theoretically the V-SWITCH technology using VLAN TAG could resolve some practical problems of IP MAN. This paper firstly analyses the architecture and services of MAN. Then aecording to the technologic principle and advantages of V-SWITCH, the paper puts forward a metropolitan interconnection solution based on V-SWITCH and the network module mode with BRAS aside by SR.
