摘要
详细分析了 ＷＤＭ光网络的结构以及联网技术的演进过程，对如何压扁网络层次，实现ＩＰ直接ｏｖｅｒ ＷＤＭ，发挥 ＷＤＭ光传送网的巨大带宽优势进行了研究，提出 ＭＰＬＳ是当前解决 ＩＰ层与光层的融合以及跨层管理问题的关键技术。
This paper has analyzed in detail the structure of WDM and the development of the techniques in optical networks. In addition, this paper has also researched on how to compress the layers of networks, realize IP direct over WDM, and utilize the huge bandwidth resource of WDM networks. We have put forward that MPLS is the key technique to solve the connection of IP and optical layer, to manage the different layers.
