联通DWDM省干线组网方案探讨

Discussion on UniCom's provincial DWDM transmission backbone networking

文章首先分析了某联通省级干线传输网的现状及不足;接着在简要介绍DWDM的技术优势后,提出并详细描述了采用DWDM技术改造现有网络的设计方案;最后讨论了该方案在实现联通网络资源优化、配置合理和网络安全保障等方面的优势及发展远景。

The paper firstly analyzes the development status and limitation of UniCom's provincial transmission backbone network. Then, after briefly introducing DWDM advan- tages, it presents and describes designing solutions for upgrading existing network by DWDM technology. Finally, in terms of optimization of UniCom's network resource, rea- sonable configuration and network security, its advantages and development direction are discussed in this paper.
