【摘要】 ＩＰ业务在世界各国的爆炸性增长对通信容量提出了越来越高的要求。密集波分复用（ＤＷＤＭ）和全光网技术的出现，提供了扩大通信容量的一种手段，如何解决 ＩＰ到光物理层的适配，尚无统一的标准。文章就此简述了 ＩＰ ｏｖｅｒ ＤＷＤＭ两种可行的实现技术 ＩＰ／ＳＤＭ／ＤＷＤＭ和 ＩＰ／Ｅｔｈ－ｅｒｎｅｔ／ＤＷＤＭ的优缺点，提出 ＩＰ／Ｅｔｈｅｒｎｅｔ／ＤＷＤＭ技术中所需要解决的问题，并构建了解决问题的模拟平台，最后针对ＩＰ／ＤＷＤＭ技术中的数据层与光层的适配、侦结构的选取、复用等问题提出了一种可行的解决方案更多还原

【Abstract】 With the development of IP services, there is the highly demand for telecommunication capacity. There are no standards to adapt IP to the optical physical layer. This article briefly describes the two realizable technologies of IP over DWDM. And the problem to be solved on IP/GBE/DWDM is presented. Then a simulative platform to solve the problems is introduced. Finally, a realizable proposal is described.更多还原
