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。巴黎圣母院的科学家们经常这样做：研究能力不足的地方系统，因为远程访问国家资源的性能不可靠；部署100 TB的本地存储，因为远程数据访问对于本地计算来说太慢了；尽管光纤连接速度为10Gbps，但校园之间的数据传输速度仍为10Mbps；从访问不同校园设施的实验数据中分离出来；或者更糟糕的是，由于大型数据集的网络传输的复杂性和低可靠性，根本不共享可用数据。研究计算中心与大学的中央企业IT组织合作，确定了那些对大学今天的科学最关键的未获资助的组件，这些组件对于支持未来日益增长的以数据为中心的科学至关重要。提出的系统解决了瓶颈，加速了科学家的桌面、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圣母大学现有的基础设施：一个新的科学DMZ，提供优化的外部网络路径，清除阻碍校园桥接的传统校园网络设备；一种新的核心交换机和路由器，为研究数据中心增加了更多的高速低延迟上行链路；以及为工程、物理和社会科学学院提供超过100个10Gb和500个1Gb新网络端口的端点构建网络升级。

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.
