CC-NIE Networking Infrastructure: Accelerating Research Data Transit Between the Scientist's Desktop, Campus, and National Cyberinfrastructure

该项目通过获取、部署和高效持续运行高性能研究网络基础设施，加速了众多数据绑定STEM领域的变革性研究。圣母大学的科学家经常遇到这样的情况：由于远程访问国家资源的性能不可靠，所以在本地系统上工作的容量不足；由于远程数据访问对于本地计算来说太慢，因此部署了数百TB的本地存储；尽管有10 Gbps的光纤连接，但仍以10 Mbps的速度在校区之间移动数据；与在不同的校区设施中获取的实验数据的访问分离；或者更糟糕的是，由于其大型数据集的网络传输复杂且可靠性差，所以没有共享可用的数据。研究计算中心与该大学的中央企业IT组织合作，确定了那些对今天的大学科学最关键、对支持未来日益以数据为中心的科学至关重要的未资助组件。建议的系统解决了瓶颈问题，加快了科学家桌面、校园和国家网络基础设施资源之间的研究数据传输(ARDT)。ARDT通过三个新组件扩展了巴黎圣母院目前的基础设施：一个新的科学DMZ，它提供了一个优化的外部网络路径，远离阻碍校园桥接的传统校园网络设备；一个新的核心交换机和路由器，用于研究数据中心，它增加了更多的更高速、更低延迟的上行链路；以及为工程、物理和社会科学系教职员工构建的终端网络升级，提供超过100个10 Gb和500个新的1 Gb网络端口。

This project accelerates transformative research in numerous data bound STEM fields through acquisition, deployment and efficient sustained operation of high capability research network infrastructure. Notre Dame scientists are too often: working on local systems of insufficient capacity because remote access to national resources is of unreliable performance; deploying 100s of TB of local storage because remote data access is too slow for local computation; moving data between campuses at 10Mbps despite fiber connectivity at 10Gbps; decoupled from access to experimental data taken in disparate campus facilities; or worse, simply not sharing available data due to the complexity and poor reliability of network transfers for their large datasets. In partnership with the University's central enterprise IT organization, the Center for Research Computing identified those unfunded components most critical to science at the University today and essential for supporting the increasingly data centric science of tomorrow. The proposed system addresses the bottlenecks, Accelerating Research Data Transit (ARDT) between the scientist's desktop, campus, and national cyberinfrastructure resources. ARDT extends Notre Dame's current infrastructure with three new components: a new science DMZ that provides an optimized external network path clear of traditional campus network appliances which hinder campus bridging; a new core switch and router for the research data center which adds many more higher speed lower latency uplinks; and endpoint building network upgrades for faculty in engineering, physical, and social sciences providing over 100 10Gb and 500 1Gb new network ports.
