At the end of this decade, national and international-scale scientific collaborative applications will need intelligent signaling and dynamic control of very-high-performance optical networks. The software proposed here will allow scientific applications to directly control an advanced, all-optical, IP-over-wavelength metropolitan-scale network, based on Dense Wave Division Multiplexing (DWDM) and photonic switching.Optical networking technology is rapidly migrating from ultra-expensive long-haul implementations to regional- and metro-area networks. The trend is to provide a general infrastructure with a wide range of common services. However, the flexibility inherent in these new technologies provides the research community with an opportunity to move beyond general requirements and support large-scale e-science applications that require advanced networking capabilities. We propose a software development effort that will lead to 21st-century applications over 1000-fiber, 1000-wavelength photonic networks.These evolving, extreme applications requiring optical networks include high-energy physics, astrophysics, climate modeling, oceanographic modeling, architectural design, molecular modeling, industrial design, advanced photon source experimentation, materials science, and industrial engineering. Underlying such applications are cross-cutting support technologies, such as advanced digital video, remote access to scientific instruments, specialized visualization displays, data-mining, cluster supercomputing and high-performance distributed computational systems. To enable the full potential of such applications, it is not sufficient to simply provide high-performance networks; these applications need intelligent, dynamic controls to adjust network resources. The proposed software development efforts will leverage the significant potential of a newly installed metro optical testbed for application-level dynamic control of resource discovery, allocation and adjustment. Efforts at many levels are required to make such flexibility available in service provisioning, infrastructure and service resource management:Research into the behavior of advanced scientific applications, not just on extremely high-performanceoptical network, but on one that can be dynamically adjusted at a granular levelIdentify application-level networking requirements, investigate management techniques for opticalnetworks, and study new service provisioning models related to application needsResearch new methods for application signalingInvestigate interconnections between application signaling and IP-based control-plane methods, such asthrough GMPLS Test deployment of those techniques on an advanced testbed and analyze resultsExperiment with multiple-service provisioning to ensure gateways to traditional networks and protocolsDevelop a system for performance metrics, monitoring and analysisCreate a testbed for StarLight, the next-generation, optically based STAR TAP, and for other advancedresearch networks.The testbed for this project is an a four-node optical network, OMNInet, initially linking a core node onNorthwestern University's Chicago campus with a node at the University of Illinois at Chicago, the CanadianNetwork for the Advancement of Research, Industry and Education (CANARIE) CA*net4 node at its Chicago Point of Presence and a node at Northwestern's Evanston campus. The sites are separated by distances of 5 to 20 miles, connected by dedicated technology trial-fiber service provided by SBC/Ameritech. Each node includes a Nortel Networks WDM photonic switch, an Optical Fiber Amplifier (OFA) and high performance router/switches. These sites will also have access to Nortel and SBC/Ameritech testing personnel, expertise, and equipment. Participants in this project, led by the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago, include the International Center for Advanced Internet Research at Northwestern University, CANARIE, Argonne National Laboratory, MREN (Metropolitan Area Research and Education Network), Nortel and Ameritech.

到本十年末，国家和国际规模的科学协作应用将需要超高性能光网络的智能信令和动态控制。这里提出的软件将允许科学应用程序直接控制基于密集波分复用 (DWDM) 和光子交换的先进全光、IP 波长城域规模网络。区域和城域网络的长途实施成本高昂。趋势是提供具有广泛公共服务的通用基础设施。然而，这些新技术固有的灵活性为研究界提供了超越一般要求并支持需要先进网络功能的大规模电子科学应用的机会。我们提出了一项软件开发工作，该工作将导致超过 1000 根光纤、1000 波长光子网络的 21 世纪应用。这些需要光网络的不断发展的极端应用包括高能物理、天体物理、气候建模、海洋建模、建筑设计、分子建模、工业设计、先进光子源实验、材料科学和工业工程。这些应用的基础是跨领域的支持技术，例如先进的数字视频、科学仪器的远程访问、专门的可视化显示、数据挖掘、集群超级计算和高性能分布式计算系统。为了充分发挥此类应用的潜力，仅仅提供高性能网络是不够的；这些应用程序需要智能、动态的控制来调整网络资源。拟议的软件开发工作将利用新安装的城域光学测试台的巨大潜力，对资源发现、分配和调整进行应用级动态控制。要在服务提供、基础设施和服务资源管理方面提供这种灵活性，需要在许多层面上做出努力：研究先进科学应用的行为，不仅是在极高性能的光网络上，而且是在可以进行细粒度动态调整的网络上。确定应用级网络需求，研究光网络的管理技术，并研究与应用需求相关的新服务提供模型研究应用信令的新方法研究应用信令和基于IP的控制平面方法之间的互连，例如通过GMPLS测试在先进的测试台上部署这些技术并分析结果进行多服务配置实验，以确保通往传统网络和协议的网关开发性能指标、监控和分析系统为 StarLight（下一代基于光学的 STAR TAP）创建测试台该项目的测试平台是一个四节点光网络 OMNInet，最初将西北大学芝加哥校区的一个核心节点与伊利诺伊大学芝加哥分校的一个节点（加拿大网络）连接起来。研究、工业和教育促进会 (CANARIE) CA*net4 节点位于其芝加哥接入点以及西北大学埃文斯顿校区的一个节点。这些站点相距 5 至 20 英里，通过 SBC/Ameritech 提供的专用技术试验光纤服务进行连接。每个节点均包括北电网络 WDM 光子交换机、光纤放大器 (OFA) 和高性能路由器/交换机。这些站点还将获得 Nortel 和 SBC/Ameritech 的测试人员、专业知识和设备。该项目由伊利诺伊大学芝加哥分校电子可视化实验室 (EVL) 牵头，参与者包括西北大学国际高级互联网研究中心、CANARIE、阿贡国家实验室、MREN（大都会地区研究和教育网络）、北电和美国科技公司。
