CC-NIE Network Infrastructure: The Future of Research and Collaboration: The Dedicated Science Network

该项目正在为耶鲁大学的网络基础设施开发两个新的主要组件：一个专用的、每秒100千兆的科学网络和一个科学DMZ。结合高速连接到国家互联网2网络，这些组件的设计使耶鲁大学的科学家和世界各地的研究人员能够在天文学、气候学、基因组学和其他科学领域的计算和数据密集型研究项目上进行合作。校园科学网络的速度比目前使用的网络快100倍。使用它，耶鲁大学的科学家们可以从他们的台式机上快速访问连接在网络上的多pb数据存储设施，以及该大学的任何高性能计算集群。对于经常处理tb级和更大数据集的科学家来说，网络速度的大幅提高是一个改变游戏规则的因素，它将传输时间从几个小时缩短到几分钟。Science DMZ的添加使研究人员能够在耶鲁大学之外共享结果，并访问国家数据存储库和XSEDE等计算基础设施。该项目建立在耶鲁大学之前对InCommon认证框架（允许外部合作者使用其所在机构的网络证书访问耶鲁大学的资源）和IPv6技术（允许更广泛、更有效地访问网络设备）的投资之上。研究人员正在使用perfSONAR设备收集性能数据，这些数据将允许他们优化和管理网络基础设施的拓扑结构，并验证其提供的性能增益。更广泛的影响：从本质上讲，该项目正在为科学合作和数据共享创建一个虚拟设施，允许在其内部形成新的研究社区和合作。通过利用科学网络和科学非军事区，耶鲁大学将能够开创新的研究合作模式；托管和服务“大数据”科学数据存储；并与所在地区、全国各地和世界各地的机构合作，扩大科学研究的机会，并为各级学生提供优质的教育和培训。

This project is developing two new major components for Yale's network infrastructure: a dedicated, 100-Gigabits-per-second Science Network, and a Science DMZ. In combination with a high-speed connection to the national Internet2 network, these components are designed to enable collaborations involving Yale scientists and researchers throughout the world on computation- and data-intensive research projects in astronomy, climatology, genomics, and other scientific fields.The on-campus Science Network provides a 100-fold increase in speed over the networks currently in use. Using it, Yale scientists, from their desktops, can rapidly access both multi-Petabyte network-attached data storage facilities, and any of the university's high performance computing clusters. Such a dramatic increase in network speed is a game changer for scientists who regularly deal with Terabyte-size and larger datasets, reducing transfer times from many hours to just a few minutes. The addition of the Science DMZ enables researchers to share results outside Yale and to access national data repositories and computational infrastructure such as XSEDE. The project builds on Yale's prior investments in both the InCommon authentication framework (which allows external collaborators to use network credentials from their home institutions to access resources at Yale), and IPv6 technology (which allows broader and more efficient access to networked devices). The investigators are using perfSONAR appliances to collect performance data that will allow them to optimize and manage the topology of the network infrastructure and validate the performance gains it delivers.Broader Impact: In essence, this project is creating a virtual facility for scientific collaboration and data sharing that will allow new research communities and collaborations to form within its walls. By leveraging the Science Network and Science DMZ, Yale will be able to pioneer new modes of research collaboration; host and serve up "big data" scientific data stores; and work with institutions in its region, across the nation, and around the world to broaden the opportunities for scientific research, and support excellent education and training for students at all levels.
