SDH网络管理系统是用来收集、传输、处理和存储有关电信网维护、运行和管理信息的综合管理系统,其网络管理的目标是最大限度增加网络的可用时间,提高网络设备的利用率、网络性能、服务质量和安全性,简化多厂家混合网络环境下的管理和控制网络运行成本,提供网络的中长期规划;文章在介绍了SDH传输网结构的基础上,给出了SDH分层信息模型的基本概念和特点,分析了SDH网络分级管理的思想和管理方法,并对电信管理网(TMN)技术进行了有益的讨论。
SDH Network Management System is an integrated management system used to collect, transmit, process and store information about maintenance, operation and management of telecommunication networks. The goal of network management is to maximize network availability, increase network equipment utilization, Performance, quality of service and security, simplifying the management and control of network operation costs under multi-vendor hybrid network environment and providing medium and long term planning of the network. Based on the introduction of SDH transport network structure, the paper presents SDH hierarchical information model The basic concepts and characteristics of SDH network are analyzed, and the thought and management method of SDH network hierarchical management are analyzed. The TMN technology is also discussed in detail.
