【摘要】：随着通信技术在信息化建设领域的发展,传输网络技术的发展也是日新月异。在激烈的市场竞争中，经过十一年时间，亳州城域传送网络有了长足的发展，传送网络具有了一定规模，已形成核心层、汇聚层、接入层三个层面较清晰的分组化城域传送网网络结构。为了满足各业务网建设对传输通道的需求，提高传送网的安全和运行质量，考虑业务网IP化和分组化传送网要求，进行组网研究，为以后业务的发展奠定基础。本论文就移动城域传送网的特点，考虑双节点组网，提出了优化的策略，并结合移动城域传送网的结构，不仅对各个层面的优化方法进行了论述，分析现有移动城域传送网的现状。通过现场勘查亳州核心层、汇聚层、接入层、互联互通城域传送网现状，分析存在问题，进行城域传送网传输带宽需求预测。针对运营商自身的网络资源情况、业务网络的规模和结构及未来的发展潜力,提出了城域传送网建设的基本思路、优化原则及优化方法，制定工程建设方案。实施完成后，对比传送网带宽改善情况，，评估城域传送网的建设效果，并进一步解决传送网带宽不佳的地方，从而达到设计方案预期目标。本论文的贡献在于通过城域传输网的分析，结合市场需求和技术发展趋势，提出了满足市场发展需求并具有可出续发展性的城域传输网络扩容传输方案。
[Abstract]:With the development of communication technology in the field of information construction, the development of transmission network technology is changing with each passing day. In the fierce market competition, after 11 years, Bozhou Metropolitan area transport network has made great progress, the transmission network has a certain scale, has formed the core layer, convergence layer, The three layers of access layer have clear packet transport network structure. In order to meet the demand of transmission channel and improve the security and operation quality of transport network, considering the requirements of IP and packet transport network, the research of network construction is carried out, which will lay a foundation for the development of service in the future. In this paper, considering the characteristics of mobile metropolitan transport network and considering the two-node network, the optimization strategy is put forward, and combining with the structure of mobile metropolitan transport network, not only the optimization methods of each level are discussed. The present situation of mobile metropolitan area transport network is analyzed. The present situation of metro transport network in Bozhou core layer, convergence layer, access layer and interconnection network is investigated. The existing problems are analyzed and the transmission bandwidth requirement of metropolitan transport network is predicted. In view of the network resources of the operators, the scale and structure of the service network and the development potential in the future, this paper puts forward the basic ideas, optimization principles and methods of metro transport network construction, and formulates the project construction plan. After implementation, the paper compares the improvement of transmission network bandwidth, evaluates the construction effect of metropolitan transport network, and further solves the problem of poor transmission network bandwidth, so as to achieve the expected goal of the design scheme. The contribution of this paper is that through the analysis of the metropolitan area transmission network, combined with the market demand and the trend of technological development, this paper puts forward a scheme of expanding the capacity of the metropolitan area transmission network, which can meet the market development demand and has the ability to develop continuously.
