摘　　要：同步数字体系(Synchronous Digital Hierarchy,SDH)光传输具有传递速度快、传输容量大等特点,且易于构建环网提升可靠性。SDH光环网在民用通信网络和电力、铁路等专用通信网络中应用广泛,能够通过网络管理系统提供强大的操作、维护及管理能力。随着SDH光环网在机动通信网络的推广应用,集中式的网络管理系统无法满足机动通信网络即插即用的需求。本文在深入研究SDH光环网网络管理技术的基础上,结合机动通信网络的组网需求,设计站号自动分配协议和拓扑自动发现算法,并在设备中进行了验证。结果表明,设计的方法能够大幅简化设备配置,提供网络拓扑呈现和光纤连接故障定位能力。Synchronous Digital Hierarchy(SDH) optical transmission has the characteristics of fast speed and large capacity, and it is easy to build a ring network to improve reliability. SDH optical ring network widely used in civil communication network and other special communication network such as electric power and railway. It provides powerful operations and maintenance capabilities through the network management system. With the popularization application of SDH optical ring network in mobile communication network, the centralized network management system can not meet the plug and play requirements. Base on the in-depth study of SDH optical ring network management technology, combined with the networking requirements of mobile communication, this paper designs the automatic site number assignment protocol and topology automatic discovery algorithm, which are verified in the equipment. It can greatly simplify the configuration and provide the network topology presentation and optical fiber connection fault location capabilities.
