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。 木文论述了宽带IP城域网的基本理论知识，包括宽带IP城域网的基木概念，宽带 IP城域网的体系结构，宽带1P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。平谷宽带IP城 域数据网建设涉及的主要技术包括：用户接入技术、IP传输技术、IP路由技术及IP地 址分配与管理等。 关键词：IP城域网 网络规划设计方案 Abstract Broad band IP MAN is a nin tegrated broad band net work, which is connected by TCP/IPprotocols, based on the manageability, the expansibility of the telecommunication network，gathering together the access of broadband and neirrowband users, meeting various needs ofbroadband multi-media services (Internet visit, VPN, etc) of group users (governmenl, enlerprises 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 TP 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 TP MAN and so on, the overal 1 requirement of Broadband TP MAN, the principle and the requirements of technologies to plan and design Broadband IP MAX. 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, TP transmission technical, TP route and TP address technical etc. Key words: IP MAN, network programming, design project.
