SDH专网的接入网网络管理系统设计

接入网是通信发展演变的主要方向之一,从网络管理的角度来看,接入网也是最复杂,最难管理的网络之一。由于光通信技术已经基本成熟,光纤接入网已成为当前接入网市场的主流。在本文SDH光纤接入网中,为了适应用户网络多种业务接入的需要,采用V5这一国际标准的数字接口作为接入网连接公共电信网的纽带。同时接入网中必须提供Q3接口,以实现电信管理网对接入网侧V5接口的管理。首先研究SDH光同步数字传输网络与专网通信。对基于本项目2.5G光纤接入平台的V5接入网,分析其V5接口结构、功能、相关协议以及V5接口系统的实现方案。在此基础上,探讨了电信管理网(TMN)的体系结构,相关协议与管理信息库。提出一种基于TMNQ3代理(Agent)的方案——管理者-代理-后台的设计方案,分析此方案的信息模型、通信协议栈及模块划分。接着,根据迈力特2.5G光纤综合业务传输网络的实际情况,在不更改此方案信息模型的基础上,用SNMP实现SDH接入网的管理并阐述其具体实现。在此之后,通过一致性测试和功能行测试,对该软件测试行进说明。

Design of Access Network System Management in SDH Private Communication Network

Access Network（AN）,one of the main trends in current telecommunication network,is the most complicated network system to manage in the view of network management.With the development of fiber communication technology,fiber integrated access devices will share the most portion of current AN devices market.In SDH Integrated Service Transmission Network,the V5 and a variety of different service access,especially the broad band service,will be required in the Service Node Interface（SNI）and the User Network Interface（UNI）respectively.And powerful network management that can provide Q3 interface will also be required.As background knowledge,the basic concept of SDH Integrated Service Transmission Network and private communication network will be discussed first.Then,the thesis gives a brief overview of network platform of Melit SDH Integrated Service Transmission Network,analyses the structure,function and protocol of V5 interface,as well as the V5 interface presented by Melit Co.,Ltd.After that,the thesis particularly probes into the architecture of TMN（Telecommunication Management Network）,related protocol and MIB.On one hand,a general model of Manager-Agent-Backend is put forward on the base of TMN Q3 interface.On the other hand,combined with the practical consideration model of V5 interface for Melit,another SNMP method is presented,without changing the Management Information Model of Q3.After that,the implement method and special function including my work will be discussed in detail.After the realization discussion,a presentation is made on the testing from the aspects of testing environment and testing content.
