Optical networks have expanded their reach from national backbone networks to metropolitan and customer access networks, and are making their way into datacenters. This has been made possible due to great strides in two arenas: optical switching technology including the development of reconfigurable optical add-drop multiplexers and wavelength-selective switches; and efficient transmission methods that enable flexible provisioning of elastic bandwidth to applications. Nevertheless, there are fundamental fiber capacity limitations that will inevitably necessitate multiple parallel fibers between switching nodes and larger switches. A solution to the switch-scaling problem is to bundle some of the wavelengths or frequency slots together and switch them as a band. Yet, current methods are inadequate because technological advancements have rendered some of the research obsolete or have introduced new problems that have not been attempted before.The objectives of this joint US-Japan project are to develop novel scalable and cost-effective multi-granular switching node architectures, and to develop efficient algorithms for provisioning bandwidth to applications. Scaling an architecture typically introduces some form of penalty, such as a provisioning constraint, that the network operator must respect. This project will aim at identifying what features bring about the most cost reduction and increase in scalability without overly limiting network operators? flexibility. The architectures and algorithms will be evaluated using theoretical analyses, simulations, and small-scale experiments.By targeting an important component of the cost of optical networks, this project will enable the faster adoption of optical infrastructure and the availability of high-speed networking for all.

光网络已将其覆盖范围从国家骨干网络扩展到大都市和客户访问网络，并正在进入数据中心。由于两个领域的进步良好：光学开关技术，包括开发可重新配置的光学附加电源多路复用器和波长选择性开关，因此已成为可能。和有效的传输方法，可以使弹性带宽适应应用。然而，基本的光纤容量限制将不可避免地需要在开关节点和较大开关之间进行多个平行纤维。解决开关尺度问题的一种解决方案是将某些波长或频率插槽捆绑在一起，然后将其切换为频段。然而，目前的方法是不足的，因为技术进步已经使一些研究过时或引入了以前未曾尝试过的新问题。该联合的美国 - 日本项目的目标是开发新颖的可扩展性和具有成本效益的多粒状切换节点体系结构，并开发有效的Algorithm，以开发有效的供应量为parvisioning bardwidth bardepations应用程序。扩展架构通常会引入网络运营商必须尊重的某种形式的惩罚，例如供应约束。该项目将旨在确定哪些功能会带来最大的成本降低和可伸缩性的提高，而不会过分限制网络运营商？灵活性。将使用理论分析，仿真和小规模实验来评估体系结构和算法。通过针对光网络成本的重要组成部分，该项目将使光学基础架构以及所有高速网络的可用性更快地采用。
