IP over SDH技术的应用研究 摘 要：SDH技术自从90年代引入以来，至今已经是一种成熟、标准的技术在骨干网中被广泛采用，且价格越来越低在接入网中应用可以将SDH技术在核心网中的巨大带宽优势和技术优势带入接入网领域，充分利用SDH同步复用、标准化的光接口、强大的网管能力、灵活网络拓扑能力和高可靠性带来好处，在接入网的建设发展中长期受益。城网直通车方案全程SDH标准，VC-12直达网络末梢汇聚侧STM-1光口上联星型网络拓扑灵活的组网为网络优化提供条件用户侧设备业务接口丰富并且具有穿透SDH核心网功能内置64K交叉连接强大的系统保护能力全程业务质量监控完善的网管系统适应未来3G网络传输SDH technology has been introduced since the 90s, it has been a mature, standard technology. It is widely used in the backbone network, and the price is getting lower and lower. Application in the access network can be SDH technology in the huge bandwidth of core network and technology advantages into the access network field, full use of SDH synchronous multiplexing, standardized optical interface, a powerful network management capabilities, flexible network topology and high capacity reliability benefits, the construction and development in the access network and long-term benefit. The design information through various search and organize the information collected, analyze, summarize, the last train made a city network networking programs. The programs main features are: full SDH standard, VC-12 directly to the network peripheral, the convergence side of the STM-1 optical interface on the Alliance, a star network topology, Flexible network optimization conditions for the network, the user interface to a rich side and have the equipment business through SDH core network functions, built-in 64K cross-connect, powerful system protection, full service quality control, improve network management system to meet the future 3G network transmission requirements.
