Ultra-High-Capacity Optical Communications and Networking: Application of Intelligent Signalling and Control of Dynamically Switched Optical Networks

在本十年末，国内和国际规模的科学协作应用将需要高性能光网络的智能信令和动态控制。本文提出的软件将允许科学应用直接控制基于密集波分复用（DWDM）和光子交换的先进、全光、ip超波长城域规模网络。光网络技术正迅速从超昂贵的长途实现向区域和城域网络迁移。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需求的机会，并支持需要高级网络功能的大规模电子科学应用。我们提出了一个软件开发工作，将导致21世纪的应用超过1000光纤，1000波长的光子网络。这些不断发展的、需要光网络的极端应用包括高能物理、天体物理、气候建模、海洋学建模、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。这些应用的基础是交叉支持技术，如先进的数字视频、对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。为了充分发挥这些应用程序的潜力，仅仅提供高性能网络是不够的；这些应用需要智能的、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试验台的巨大潜力，用于资源发现、分配和调整的应用级动态控制。要在服务供应、基础设施和服务资源管理方面实现这种灵活性，需要在多个层面上做出努力：研究先进科学应用的行为，不仅是在高性能的光网络上，而且是在可以在粒度水平上动态调整的光网络上识别应用级网络需求，研究光网络的管理技术，研究应用信令的新方法研究应用信令与基于ip的控制平面方法之间的互连，例如通过GMPLS在先进的测试平台上测试这些技术的部署并分析结果多业务提供实验以确保传统网络和协议的网关开发一个性能指标系统。为StarLight（下一代光学STAR TAP）和其他先进研究网络创建一个测试平台。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、加拿大研究、工业和教育促进网络（CANARIE）芝加哥存在点的CA*net4节点和西北大学埃文斯顿校区的一个节点连接起来。这些站点相距5到20英里，由SBC/Ameritech提供的专用技术试验光纤服务连接。每个节点包括北电网络WDM光子交换机、光纤放大器（OFA）和高性能路由器/交换机。这些站点还将获得北电和SBC/Ameritech的测试人员、专业知识和设备。该项目的参与者由伊利诺伊大学芝加哥分校电子可视化实验室（EVL）领导，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（都市研究和教育网络）、北电和Ameritech。

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.
