CC* Networking Infrastructure: Building a Science DMZ for Data-intensive Research and Computation at the University of South Carolina

南卡罗来纳州大学（UofSC）正在建立一个新的网络，即科学DMZ，以100 Gbps的速度运行。科学DMZ支持当前在UofSC和国家实验室之间移动TB级数据的研究（例如，阿贡、费米、橡树岭、萨凡纳河、洛斯阿拉莫斯）、大学合作者和国家超级计算机中心网络（XSEDE）。该项目符合国家利益，因为它解决了将UofSC连接到国家“网络高速公路”系统以共享大科学数据的需求，从而促进合作和国家竞争力，与NSF的使命保持一致。新的网络基础设施还允许研究人员与分布在世界各地的合作者交换大型数据集。例子包括瑞士保罗·谢勒研究所的核物理结果和意大利稀有事件低温地下观测站的观测文件。UofSC科学DMZ的要素包括：i）数据传输节点（DTN），用于在广域网上高速发送/接收数据; ii）连接DTN、仪器、存储设备和计算系统的高吞吐量、无摩擦路径; iii）用于监控端到端路径的测量设备; iv）为高性能环境量身定制的安全策略。拟议的科学DMZ大大增加了计算和XSEDE资源的带宽，允许它们用于数字图像相关，半导体材料开发，DNA/RNA测序和其他领域。此外，UofSC拥有关键的国家资源和中心，包括美国部署的第一台飞行时间电感耦合等离子体质谱仪，NOAA的国家河口研究储备数据库，麦克奈尔航空航天中心和巴鲁克研究所。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The University of South Carolina (UofSC) is establishing a new network, namely a Science DMZ, operating at 100 Gbps. The Science DMZ supports current research moving terabyte-scale data between UofSC and national laboratories (e.g., Argonne, Fermi, Oak Ridge, Savannah River, Los Alamos), university collaborators, and the national network of supercomputer centers (XSEDE). The project serves the national interest, as it addresses the need to connect UofSC to the national "cyber-highway" system to share big science data, hence promoting collaboration and national competitiveness, aligned with NSF's mission. The new cyberinfrastructure also permits researchers to exchange large datasets with collaborators geographically distributed across the world. Examples include nuclear physics results from the Paul Scherrer Institute in Switzerland and observation files from the Cryogenic Underground Observatory for Rare Events (CUORE) in Italy. The elements of UofSC's Science DMZ include: i) data transfer nodes (DTNs), built for sending/receiving data at a high speed over wide area networks; ii) high-throughput, friction-free paths connecting DTNs, instruments, storage devices, and computing systems; iii) measurement devices to monitor end-to-end paths; and iv) security policies tailored for high-performance environments. The proposed Science DMZ substantially increases the bandwidth to compute and XSEDE resources, permitting their use on digital image correlation, semiconductor material development, DNA/RNA sequencing, and other areas. Additionally, UofSC hosts key national resources and centers including the first U.S. deployed Time of Flight-Inductively Coupled Plasma-Mass Spectrometer, NOAA's National Estuarine Research Reserves database, McNair Aerospace Center, and Baruch Institute. These resources are now more efficiently used by researchers and collaborators.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
