结项摘要
"三维以太城域网（3D-EMAN）体系结构研究"针对DWDM所提供的Tbps速率，能够满足未来电视、电话和计算机网络"三网合一"需要，而现有的城域网技术都是基于3层（Internet）或2层（MPLS）用户数据传输平台，传输效率低，不能满足实时性强的视像数据服务质量需求和真正实现"三网合一"而提出。.本项目研究重点是：如何利用带外信控技术将城域网的用户平面降低到物理层，同时在信控和管理平面保留Intenet协议栈，以便在实现与Internet的互通同时，保证高效的用户数据传输和服务质量。.本实验室的预研工作已经初步验证了3D-EMAN的可行性，为在DWDM上实现物理层交换技术，已经提出并着手研究异步传输模式下的"物理帧时槽交换技术"（PFTS）[1、2]。物理帧借用未来的主流技术以太网的帧格式，互联简单，PFTS优于国际上的Burst Switching和Packet Switching
