CC-NIE Network Infrastructure: Network 10Gb Upgrade and Science DMZ Implementation to Support Science and Engineering Research and Enhance Outreach for High School STEM Education

高性能数据网络是研究人员和教育工作者的关键基础设施，他们依靠畅通无阻地访问远程仪器、海量数据集和远程合作者来实现科学和工程领域的目标。该项目在代顿大学建立了一个高性能的研究网络，通过州和国家的高容量网络提供与其他研究机构的畅通无阻的连接。该项目将校园网络从1 Gb扩展到10 Gb，并在校园内的四个科学和工程设施中建立了科学DMZ，为研究人员提供了新的能力。研究活动将研究人员与同事和学生联系起来：(1)辛克莱社区学院和地区高中的教育和推广活动；(2)俄亥俄州立大学的远程仪器访问；(3)俄亥俄超级计算机中心的气候研究远程处理；以及(4)中央州立大学(一所历史上的黑人大学)的协作传感器研究。这一网络扩展将该大学以10Gbps的速度连接到Internet2和OARnet的IntraOhio(均以100Gbps运行)。此外，代顿大学正在利用PerformSONAR监测来测量和记录科学非军事区的性能。该项目的关键升级包括在代顿大学安装科学非军事区边缘硬件和升级分配和接入层，以及在中央州立大学对科学非军事区连接进行硬件升级。这些改进使我们的科学家和工程师能够更好地连接、协作和共享科学数据，提供强大的STEM教育外展，为高价值劳动力发展做出贡献，并为共享稀缺的科学资源创建具有成本效益的模式。

High performance data networks are critical infrastructure for researchers and educators who rely on unimpeded access to remote instrumentation, massive data sets and distant collaborators to achieve objectives in science and engineering fields. This project builds a high-performance research network at the University of Dayton to provide unimpeded connections to other research institutions via state and national high-capacity networks. The project expands the campus network from 1Gb to 10Gb and establishes science DMZs in four science and engineering facilities across the campus, providing researchers with new capabilities. Research initiatives link researchers with colleagues and students for: (1) education and outreach initiatives at Sinclair Community College and regional high schools, (2) remote instrumentation access at The Ohio State University, (3) climate research remote processing at the Ohio Supercomputer Center, and (4) collaborative sensors research at Central State University (a historically black university). This network expansion connects the University at 10Gbps to Internet2 and OARnet's IntraOhio (both running at 100Gbps). Additionally, the University of Dayton is utilizing perfSONAR monitoring to measure and document the performance of the science DMZs.The key upgrades for this project include installing science DMZ edge hardware and upgrading distribution and access layers at the University of Dayton, and hardware upgrades for science DMZ connections at Central State University. These improvements enable our scientists and engineers to better connect, collaborate, and share science data, provide robust STEM educational outreach, contribute to high-value workforce development and create cost-effective models for sharing scarce scientific resources.
