Scaling Terabit Networks: Breaking Through Capacity Barriers and Lowering Cost with New Architectures and Technologies

该项目将于2013年9月19日至20日在位于华盛顿特区的美国光学学会（OSA）总部举行，主题为“扩展太比特网络：利用新架构和技术突破容量障碍并降低成本”。研讨会的目标是为光网络社区制定一套“大挑战”。这将通过以下方式实现：探索由不断变化的流量模式、虚拟化和可编程性驱动的新网络架构如何驱动对光学的新需求，以及新兴的光子组件如何帮助将这些架构扩展到太比特容量；重新思考操作系统接口和网络应用程序接口；探索哪些物理层现象和特征需要传达给更高层，哪些更高层的功能可以从物理层智能中受益；并了解光学和电子学将如何在未来一起使用，以及它们各自的指标在光网络环境中一起使用时会是什么。在讨论这些技术领域时，将组织讲习班以实现以下目标：确定太比特网络面临的技术挑战和继续扩大网络规模；为高效和可扩展的太比特网络建立关键指标、目标和能力；在光网络中设置研究优先级和要求，以实现高效和可扩展的太比特网络；并确定应用程序驱动程序和这项新技术的早期采用者。超高容量光网络是数据驱动科学正在进行的革命的关键推动者。它们也是美国维持国家竞争力和国家安全所需的关键基础设施技术的一部分。通过向美国研究界以及美国国家科学基金会和其他联邦机构通报关键研究问题和机会，该研讨会将支持美国的国家利益。讲习班的最后报告将向公众公布。

This project is for a workshop on "Scaling Terabit Networks: Breaking Through Capacity Barriers and Lowering Cost with New Architectures and Technologies," to be held at the Optical Society of America (OSA) headquarters in Washington, DC, on September 19-20, 2013. The goal of the workshop is to develop a set of "grand challenges" for the optical networking community. This will be accomplished by: exploring how new network architectures driven by changing traffic patterns, virtualization and programmability drive new requirements for the optics, and how emerging photonic components can help scale these architectures to terabit capacities; rethinking the operating system interface and application interface to the network; exploring what physical layer phenomena and characteristics need to be communicated to the higher layers and what higher-layer functions can benefit from physical layer intelligence; and understanding how optics and electronics will be used together in the future and what their respective metrics will be when used together in an optical networking context.In addressing these technical areas, the workshop will be organized to achieve the following objectives: identify the technological challenges facing terabit networks and continued network scaling; establish key metrics, targets, and capabilities for efficient and scalable terabit networking; set research priorities and requirements within optical networking to enable efficient and scalable terabit networking; and identify application drivers and early adopters of this new technology.Ultra-high capacity optical networks are the key enabler of the ongoing revolution in data-driven science. They are also part of critical infrastructure technologies that the United States needs to maintain national competitiveness and national security. By informing both the U.S. research community as well as NSF and other Federal agencies about key research problems and opportunities, this workshop will support U.S. national interests. The final workshop report will be made publicly available.
