【摘要】：分组传送网是新型的城域宽带传输网络，是适合于传送有线或无线电信业务、电视和数据业务的统一传输平台，是符合NGN要求的传输基础。随着全业务网IP化的发展，，传送网全IP化已是今后发展的大方向。PTN技术已成为本地和城域传送网向IP化演进的主流技术之一，在现有网络中获得了大量的应用。本文主要的研究目的是为了使本人单位和杨柳青网路维护中心合作建设分组传送网期间，能够更好的提高网络维护水平。通过对系统关键指标的研究，进一步掌握系统的建设与后期维护工作，以便于今后能够很深入扎实的开展对分组传送网的建设与维护保养工作。本文的主要研究方法是用理论分析与实际测量测试结果进行综合比较的方式。首先对系统的重要参数指标：网络节点、核心层、汇聚层、接入层、企业与家庭需要进行分析与研究。说明其在实际工作中的意义，而后通过运用工作中的实地测量，将实际信息与得到的结果进行分析。通过对实地的分析，指出其影响因素，调整相关参数和设置，观察对建造后结果的影响。最终找出最佳的网络建设方案。通过对系统指标进行理论分析研究和实际测试测量，使得原先的系统参数得到了进一步的优化，系统参数得到了进一步的提高，抗干扰性能加强。最终在杨柳青地区铺设完成分组传送网络，并将原有网络进行优化整合。
[Abstract]:Packet transport network is a new type of metropolitan broadband transmission network. It is a unified transmission platform suitable for the transmission of wired or wireless telecommunication services, television and data services, and is the transmission basis that meets the requirements of NGN. With the development of IP in all-service network, the all-IP technology of transport network has become one of the mainstream technologies in the evolution of local and metropolitan transport networks to IP, and has been widely used in existing networks. The main purpose of this paper is to make our unit and Yangliuqing Network maintenance Center cooperate in the construction of packet transport network, which can improve the level of network maintenance. Through the study of the key indexes of the system, the construction and maintenance of the system are further grasped, so that the construction and maintenance of the packet transport network can be carried out in a very deep and down-to-earth manner in the future. The main research method of this paper is to make a comprehensive comparison between the theoretical analysis and the actual measurement results. Firstly, the important parameters of the system, such as network node, core layer, convergence layer, access layer, business and family needs, are analyzed and studied. Its significance in practical work is explained, and the actual information and the obtained results are analyzed by using the field measurement in the work. Through the field analysis, the paper points out the influencing factors, adjusts the relevant parameters and settings, and observes the influence on the results after construction. Finally find out the best network construction plan. Through the theoretical analysis and measurement of the system parameters, the original system parameters are further optimized, the system parameters are further improved, and the anti-interference performance is enhanced. Finally in Yangliuqing area the completion of packet transport network, and the original network optimization integration.
