本文介绍了多播波长路由网络的节能设计空间。节能设计空间是基于功耗对波长路由网络整体设计的影响。研究了基于该设计理念的两种交叉连接架构。一种是现有的称为拆分和交付（SaD）的体系结构。另一种是一种新的体系结构，称为仅组播分配器和分发（MOSaD）。MOSaD架构仅为组播连接使用功率分配器，允许单播连接通过而不会遭受不必要的功率损失。我们的交叉连接设计为单播连接提供了严格的非阻塞服务，同时消除了SaD交叉连接的不必要功率损耗。实验结果表明，MOSaD架构在极大地节省成本和降低信号功率损耗的同时，对网络的阻塞性能影响最小。
In this paper, we introduce the power-efficient design space for multicast wavelength-routed networks. The power-efficient design space is based on the impact of power on the overall design of wavelength-routed networks. Two cross-connect architectures on this design concept are investigated. One is an existing architecture called splitter-and-delivery (SaD). The other is a new architecture called multicast-only splitter-and-delivery (MOSaD). The MOSaD architecture uses power splitters for multicast connections only, allowing unicast connections to pass without enduring unnecessary power losses. Our cross-connect design provides a strictly nonblocking service for unicast connections while eliminating unnecessary power loss of the SaD cross-connect. Experimental results demonstrate that the MOSaD architecture provides substantial savings in cost and reduction in signal power loss with minimal effects on the blocking performance of the network.
