Abstract

A Colorless and Directionless (C&D) ROADM architecture has empowered today's networks with the much needed flexibility and scalability to handle the unpredictable high bandwidth demands, provide any-to-any connectivity and provision new services without disrupting the existing ones. In this paper, we realize the C&D ROADM architectures using PXC and WSS at a multi-degree node. We then evaluate both the architectures based on the various advantages offered by them. We also discuss some of the drawbacks of the two architectures. Subsequently, we propose a Colorless, Directionless and Contentionless (CD&C) architecture which combines the features offered by both the C&D architectures. Finally, we discuss practical implementation issues of the proposed architecture.
网状光网络的无色、无方向、无争议多度ROADM架构
无色无方向(C&D) ROADM架构赋予当今网络所需的灵活性和可扩展性,以处理不可预测的高带宽需求,提供任意对任意连接,并在不中断现有服务的情况下提供新服务。在本文中,我们利用PXC和WSS在多度节点上实现了C&D ROADM架构。然后,我们根据它们提供的各种优势来评估这两种体系结构。我们还讨论了这两种体系结构的一些缺点。随后,我们提出了一种无色、无方向和无争议(CD&C)架构,它结合了C&D架构所提供的特性。最后,我们讨论了所提出的体系结构的实际实现问题。
