摘要
近年来,随着数据业务的迅速发展,城域传送网已成为电信运营商开拓用户市场和增强业务提供能力的关键。因此,如何有效地支持数据业务是新一代城域传送网建设所面临的关键问题。此外,话音和TDM专线业务仍是运营商收入的主要来源,所以如何在保证TDM业务传送的同时提供数据业务的传送和处理功能是市场发展的需求。于是,以SDH为基础的多业务传送平台(MSTP)技术应运而生,并已成为近期城域光传送网的一个主流解决方案。
本论文第一章首先提出了MSTP的概念,对MSTP的优势进行了讨论;第二章探讨了MSTP的技术特点和新一代关键技术,包括GFP封装协议、VC虚级联和链路容量自动调整机制(LCAS)以及弹性分组环(RPR)和多协议标签交换(MPLS)等关键技术;第三章重点介绍了MSTP在通信领域的应用,比如MSTP在城域网、本地网、3G光网络中的应用,并详细阐述了MSTP在这几种应用中的技术要求;第四章针对MSTP在应用中存在的如MSTP的互连互通问题和MSTP和数据设备的关系等问题进行了剖析;第五章分析了MSTP在未来的发展方向和技术趋势;第六章对全文进行了总结。

Abstract
In recent years, with the rapid development of data services, metro work has e a munications operator to open up markets and enhance business users the ability to provide the key. Therefore, how to effectively support data services are a new generation of metro work construction of the key questions facing. In addition, TDM voice and green business operators are still the main source of e, so how to ensure the transmission of TDM business operations at the same time provide data transmission and processing functions are the development of the market demand. Thus, in order to SDH-based Multi-Service Transport Platform (MSTP) technology came into being, and has e a recent Metro Optical work, a mainstream solution.
The first chapter of this thesis first put forward the concept of the MSTP, the advantages of MSTP discussed; MSTP chapter discusses the technical features and a new generation of critical technologies, including GFP protocol package, VC virtual concatenation and link capacity automatically adjust mechanism (LCAS) and Resilient Packet Ring (RPR) and Multi-protocol Label Switching (MPLS) and other key technologies; Chapter III focuses on the MSTP at the field munications applications, such as MSTP at Metro, the work, 3G works Application and detailed MSTP applications in these types of technical requirements; fourth chapter in the application for MSTP such as the exis
