网络的信息模型把网络的技术实现和管理连结在一起.本文介绍了以同步数字系列(SDH)技术为基础的电信网的信息模型结构和工作原理.一、引言通信系统的发展要求有先进的管理系统与之相适应.管理系统最主要的部分就是信息模型,是它实现了通信系统和管理系统之间的连结,描述了通信系统中有关网管的所有内部状态和拓扑因素.管理系统的每一项观测都基于信息模型,而且所有的反应也都是作为管理行为通过信息模型反馈回网络.随着网络规模和复杂程度的增大,信息模型内部所属因素、网元和信息模型之间,以及那些建立在信息模型基础上的任务也都变得越来越复杂.对于大型网络,例如那些国营电信公司,对信息模型的明确定义和理解就尤为重要.这样的网络往往是不同厂家的设备之间相互配合工作,设备之间的接口和设计只能由信息模型实现,这样的信息模型不但要被厂家和运营公司所接受,还要让他们了解.
The information model of the network links the technology realization and management of the network.This paper introduces the structure and working principle of the information model of the telecommunication network based on Synchronous Digital Hierarchy (SDH) technology I. Introduction The development of communication system requires advanced The management system is compatible with it.The most important part of the management system is the information model, which realizes the connection between the communication system and the management system, and describes all the internal states and topological factors about the network management system in the communication system One observation is based on the information model, and all the responses are also fed back to the network through the information model as the management behavior.With the increase of the network size and complexity, between the elements of the information model, the network element and the information model, As well as those based on the information model are also becoming more complex.For large networks, such as those of state-owned telecommunications companies, the clear definition of the information model and understanding is particularly important.Such networks are often different manufacturers of equipment Work with each other, the interface between devices and design can only be achieved by the information model, such information Type not only to be accepted by manufacturers and carriers, but also to let them know.
