EIN: Collaborative Research: End-to-end Provisioned Optical Network Testbed for Large-Scale eScience Applications

该提案是一项全面的努力，旨在开发基础设施和网络技术，以支持广泛的电子科学项目，特别是Terascale超新星计划。拟议的工作将建立一个高性能的实验性光网络基础设施，支持：（a）按需提供端到端高速电路，（B）稳定的传输以维持控制和流操作，以及（c）中间件和应用软件以支持数据传输、可视化、转向和控制。通过这些组件的垂直整合，研究人员计划展示大规模eScience应用（如TSI）如何充分利用光网络的优势。该团队由光网络研究人员、传输层和中间件研究人员以及射电天文学科学家组成。该项目的成功完成将使获奖者能够确定创建一个主干高速共享电路交换网络的收益和成本，该网络沿着与两个分组交换Internet 2主干网络Abilene和vBNS相同的线路。更广泛的影响：由于目标eScience应用范围广泛，该项目应具有广泛的社会影响。鉴于这一项目的研究人员队伍各不相同，应迅速在各研究界传播成果，提高对这一方法的兴趣。该项目极大地利用了各大学和ORNL的各种资源。这些大学的学生将获得ORNL的计算和网络资源，包括超级计算机和高带宽链接。此外，这项工作将用于为美国能源部教育项目的学生提供项目，该项目支持全国各地大学的本科生和研究生。该项目将特别包括来自ORNL的少数民族研究联盟计划的暑期学生。

This proposal is a comprehensive effort to develop the infrastructure and networking technologies to support a broad class of eScience projects and specifically the Terascale Supernova Initiative. The proposed work will build a high-performance, experimental, optical network infrastructure that supports: (a) on-demand provisioning of end-to-end high-speed circuits, (b) stable transport to sustain control and streaming operations, and (c) middleware and application software to support data transfers, visualization, steering and control.Intellectual Merit: Through a vertical integration of these components, the researchers plan to demonstrate how a large-scale eScience application, such as TSI, can fully exploit the benefits of optical networks. The team consists of optical networking researchers, transport-layer and middleware researchers, and radio-astronomy scientists. Successful completion of this project will allow the Awardee to determine the benefits and costs of creating a backbone high-speed shared circuit-switched network along the same lines as the two packet-switched Internet2 backbone networks, Abilene and vBNS.Broader impact: Due to the broad spectrum of target eScience applications, the project should have a broad societal impact. Given the diverse team of researchers on this project, results should be disseminated in various research communities rapidly and increase the level of interest in this approach. This project significantly leverages various resources at the universities and ORNL. Students from these universities will be provided access to computational and network resources at ORNL, in terms of supercomputers and high-bandwidth links. Also, this work will be used to provide projects to students from DOE educational programs, which support undergraduate and graduate students from universities across the country. This project will specifically include summer students from ORNL's Research Alliance for Minorities program.
