CC* Networking Infrastructure: Deploying a Science DMZ to Advance Research at the University of Montana

蒙大拿大学（UM）使命的一个主要组成部分是产生世界一流的研究和创造性的奖学金。为此，UM建立了最先进的模块化数据中心，确保了关键校园站点的专用高速连接，并部署了共享计算集群。一个由研究人员和IT专业人员组成的团队，审查了网络基础设施计划以及研究人员的需求，确定需要一个配置良好的专用网络来实现高性能以太网，以推进UM的使命。该项目安装了一个科学DMZ（UM-DMZ），一个独立的无摩擦网络，专门用于科学数据传输，到UM的研究基础设施。UM-DMZ沿着强大的研究基础设施，为需要访问高性能端到端数据传输以开展工作的优质学生、教育工作者和研究人员提供服务并吸引他们。硬件包括使用Arista网络交换机，该交换机可实现低延迟和深度数据包缓冲。它支持sFlow并满足IPv4和IPv6科学应用的需求。部署了各种规模的数据传输节点，并使用Zeek IDS系统和网络安全策略建立了坚实的安全基础。UM-DMZ为影响社会福祉的不同学科的研究工作提供服务。这包括对环境和气候变化的研究，基因组研究，用于进一步科学发现的工具的开发，以及创新的学生主导的研究项目。这些不同项目的共同主题是增强协作、高速数据传输和为学生提供教育机会。学生通过先进的网络课程，实习和学生领导的研究参与，是这个项目的重要方面。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。

A major component of the University of Montana's (UM) mission is to generate world-class research and creative scholarship. To that end, UM established a state-of-the-art Modular Data Center, ensured dedicated high-speed connections for key campus sites, and deployed a shared computing cluster. A team of researchers and IT professionals, reviewing the cyberinfrastructure plan alongside researcher needs, determined that a well-configured dedicated network for high-performance dataflow is needed to advance UM's mission. This project installs a Science DMZ (UM-DMZ), a separate friction-free network dedicated to scientific data transfer, into UM's research infrastructure. The UM-DMZ, along with a robust research infrastructure, serves and attracts quality students, educators and researchers who require access to high performance end-to-end data transfers to conduct their work.Hardware includes using an Arista network switch that allows for low-latency and deep packet buffering. It supports sFlow and meets the needs for IPv4 and IPv6 scientific applications. Various sized Data Transfer Nodes are deployed and a solid security foundation using Zeek IDS system and network security policies are being implemented. The UM-DMZ serves research efforts from diverse disciplines that impact the well-being of society. This includes research on the environment and climate change, genomic studies, the development of tools used to further scientific discovery, and innovative student led research projects. Common themes uniting these diverse projects are enhanced collaboration, high-speed data transfer, and educational opportunities for students. Student participation through advanced network courses, internships, and student led research, are important aspects of this project.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.
