摘要
随着邮政业务的快速发展,基于邮政信息网的系统不断增加,邮政信息网承载的数据传输量明显增大,如何充分利用有限的线路资源,减少通信线路费用的支出,加强数据传输的安全性和可靠性,已经成为目前迫切需要解决的问题。
为了进一步满足邮政业务的发展,有必要对现有的广域网网络和线路进行调整和优化,即整合全网通信资源,优化网络和线路结构。本文通过了解、分析邮政网部分省份及其他行业的线路复用技术,对邮政信息网网络架构及线路类型的选择提供了合理的建议。
根据邮政业务发展的需求,本文结合邮政网广域网的现状,同时结合线路复用的现状及新技术的发展,对虚拟电路、复用器、MPLSVPN、IP混合等几种线路复用技术进行了深入的分析和对比,探讨符合邮政实际,经济合理、技术可行的省内邮政信息线路复用的模式。
通过对邮政信息网线路复用方案的研究,可以看出线路复用不仅可以使邮政信息网的线路资源得到整合,网络结构更加合理,更为邮政业务的进一步发展的提供了动力。
With the development of postal service and much more increase in the system based on postal information network, the transmission quantity of the data the network bear is distinctly rising .So it has become the first problem to be solved at the moment for how to take advantage of the limit lines resource, and reduce the expenditure of the lines of communication, and enhance the security and reliability of the data transmission.
In order to meet the further need of postal service development, we need to regulate and optimize the wide network and lines, namely combine all the network communication resource and optimize the network and lines structure .This paper offers some reasonable advice about the selection of the structure of the post information network and lines pattern by comprehending and analyzing the multiplex lines technique in some provinces and other industry.
According to the need of the postal service development, this paper deeply analyzes and contrasts with the technique of some multiplex lines such as virtual circuits, multiplex implements, mpls vpn and ip, plus probing into the multiplex pattern of the post information lines in province which is according with the post actuality, economic rationality and technical feasibility at the same time by combining the reality of the post wide network, coupled with the situation of the multiplex lines and development of the new technique.
We can see that multiplex lines can not only combine all the lines resource of the postal service and optimize the network structure, but put forward the further development of the postal service through the research of the multiplex project of the postal service lines.
