This ITR proposal is a request for funding to develop and deploy UltraLight, the first of a new class of integrated information systems that will support the decades-long research program at the Large Hadron Collider (LHC) and other next generation sciences. Physicists at the LHC face unprecedented challenges: (1) massive, globally distributed datasets growing to the 100 petabyte level by 2010; (2) petaflops of distributed computing; and (3) collaborative data analysis by global communities of thousands of scientists. In response to these challenges, the Grid-based infrastructures developed by the LHC collaborations provide massive computing and storage resources, but are limited by their treatment of the network as an external, passive, and largely unmanaged resource. UltraLight will overcome these limitations by monitoring, managing and optimizing the use of the network in realtime, using a distributed set of intelligent global services. The UltraLight hybrid packet- and circuit-switched network infrastructure will employ ultrascale protocols and dynamic building of optical paths to provide efficient fair-sharing on long range networks up to the 10 Gbps range. UltraLight's scope offers exciting and unusual educational outreach opportunities for students. It provides direct and significant support for E&O activities including: application development, experiment participation, infrastructure deployment, and internships at participating institutions. Existing outreach programs within the GriPhyN, iVDGL, and e-VLBI Grid projects, as well as Florida International University's CHEPREO and CIARA programs, will be exploited to attract undergraduates to physics and math, and to inject new important elements of information technology into core graduate science domains.

该 ITR 提案请求资助开发和部署 UltraLight，这是第一个新型集成信息系统，将支持大型强子对撞机 (LHC) 和其他下一代科学领域长达数十年的研究计划。 LHC 的物理学家面临着前所未有的挑战：(1) 全球分布的海量数据集到 2010 年将增长到 100 PB 水平； (2) 千万亿次分布式计算； (3) 全球数千名科学家的协作数据分析。 为了应对这些挑战，大型强子对撞机合作开发的基于网格的基础设施提供了大量的计算和存储资源，但由于它们将网络视为外部、被动和很大程度上不受管理的资源而受到限制。 UltraLight 将通过使用一组分布式智能全球服务实时监控、管理和优化网络的使用来克服这些限制。 UltraLight 混合分组和电路交换网络基础设施将采用超大规模协议和动态光路构建，在高达 10 Gbps 范围的远程网络上提供高效的公平共享。 UltraLight 的范围为学生提供了令人兴奋和不寻常的教育推广机会。它为 E&O 活动提供直接且重要的支持，包括：应用程序开发、实验参与、基础设施部署以及参与机构的实习。 GriPhyN、iVDGL 和 e-VLBI Grid 项目以及佛罗里达国际大学的 CHEPREO 和 CIARA 项目中现有的外展项目将被用来吸引本科生学习物理和数学，并向核心研究生注入新的重要信息技术元素科学领域。
