【摘要】：随着中国经济的高速发展和信息通信技术的广泛应用，人们对信息网络的需求日渐增多。近期安全泄密事件的爆发使得银行、公安等众多大型企业和政府部门意识到，租用电信运营商专线来构建行业内部的城域业务网仍存在安全隐患。如何在不借助运营商网络的情况下设计出“多业务承载、安全、经济的新兴城域网”成为城域网建设的新课题。本文从城域网分层体系结构入手，，逐层分析和研究了城域骨干网、宽带接入网和线路传送通道建设的多种技术手段。在此基础上，根据城域网的组网原则及组网思路，阐述了对这三个子模块关键技术的分析比较过程，提出了以基于SDH的MSTP为城域骨干网组网技术、基于EPON的FTTx为城域接入网方案、以城市地铁管道为线路传输通道的新兴城域网设计模型，该模型满足“多业务承载、安全、经济”的要求。并在不同城市环境下进行模型细化，并应用到江苏某新兴城域网的设计方案中。
[Abstract]:With the rapid development of China's economy and the wide application of information and communication technology, the demand for information network is increasing. The recent outbreak of security leaks has made banks, public security and other large enterprises and government departments realize that renting the special line of telecom operators to build the inner city business network of the industry still has security risks. How to design "multi service bearer, safe and economic new metropolitan area network" without the help of the operator network has become a new topic in the construction of metropolitan area network.
This paper, starting with the hierarchical architecture of the metropolitan area network, analyzes and studies various technical means for the construction of metropolitan backbone network, broadband access network and line transmission channel by layer by layer. On this basis, the analysis and comparison process of the key technologies of the three sub modules are expounded based on the networking principles and networking ideas of the metropolitan area network, and the MS based on SDH is proposed. TP is the city backbone network networking technology, based on the EPON FTTx as the city access network scheme, the new city domain network design model with urban subway pipeline as the line transmission channel is designed to meet the requirements of "multi service, security and economy". The model is refined in different urban environment and applied to the design of a new city area network in Jiangsu. In the scheme.
