传输网络作为各种通信业务的有效载体是整个通信网络的基础。各通信运营商为了吸收更多的客户不断推出新的业务,所以新时期的传输网络的发展必将影响到运营商的业务开展。城域传输网是整个传输网络中最复杂的部分,它的运行不仅要考虑到本地传输距离还要考虑业务的流量和流向以及各种通信终端接口,因此传输网络的优化势在必行。本文通过对城域网的概述,按技术划分的传输网络规划方案优缺点的详细阐述,进而提出网络优化的原则和策略。
Transmission network as an effective carrier of various communication services is the basis of the entire communication network. In order to attract more customers to continuously launch new services, the development of transmission networks in the new era will surely affect the business development of operators. Metro transport network is the most complex part of the entire transport network, its operation not only to account for the local transmission distance but also consider the traffic and flow of business and a variety of communication terminal interface, so the transmission network optimization is imperative. This article through the metropolitan area network, according to the technical division of advantages and disadvantages of transmission network planning program elaborate, and then put forward the principle and strategy of network optimization.
