毕业设计（论文）-IP城域网的网络规划与应用设计.doc

摘 要 宽带 IP 城 域 网是采用TCP/IP协议互联起来的，以电信网的可管理性、可扩充性为基础，在城市的范围内汇聚宽、窄带用户的接入，面向满足集团用户(政府、企业等)个人用户对各种宽带多媒体业务(互联网访问、虚拟专网等)需求的综合宽带网。 本文的主要研究目的是对平谷宽带IP城域网进行规划和设计，使其成为一个性能优良的、可运营可管理的、可盈利可扩展的安全的可持续发展的宽带IP城域网。 本文论述了宽带IP城域网的基本理论知识，包括宽带IP城域网的基本概念，宽带IP城域网的体系结构，宽带IP城域网组网的主要技术的基本原理以及技术本身的优缺点，宽带IP城域网组网的主要接入技术及其适用的范围等，宽带IP城域网的总体要求，宽带IP城域网网络规划设计的原则和技术要求。 本文简要研究了宽带网的层次性结构：骨干层、汇聚层、接入层。 Abstract Broad band IP MAN is a nintegrated broad band network,which is connected by TCP/IPprotocols, based on the manageability, the expansibility of the telecommunication network,gathering together the access of broadband and narrowband users, meeting various needs ofbroadband multi-media services (Internet visit, VPN, etc) of group users (government,enterprises and so on)and personalusers. The main research purpose of the thesis is to reasonably plan and design The Broadband IP MAN of Pinggu Network, making it to be an excellent performance, administrationable, manageable, profitable, extensible, safe and developable continuously broadband IP MAN. The thesis discusses the Basic theory of the Broadband IP MAN,including the Basic concept of Boadband IP MAN,the system structure of Broadband IP MAN,the Basic principle,merits and demerits of main technologies to organize Broadband IP MAN,the main access technologies and the adaptive scope to organize Broadband IP MAN and so on, the overall requirement of Broadband IP MAN,the principle and the requirements of technologies to plan and design Broadband IP MAN. This thesis briefly introduces the hierachical structure of the broadband network : the core layer, the distribution layer, and the access layer. In the execution of Data MAN Project,some key technical shall be the essential element: The terminal access technical,IP transmission technical,IP route and IP address technical etc. Key words: IP MAN, network programming，design project. 目 录 第1章 引 言 5 1.1 课题背景 5 1.2 研究内容 6 第2章 城域网技术 7 2.1 基本概念 7 2.2 基本业务 7 2.2.1 业务类型 7 2.2.2 典型业务描述 8 2.2.3 其它增值业务 9 2.4 网络传输技术
