CC* Networking Infrastructure: Creation of a Science DMZ and 10Gb/s Connection to Internet2 for Tennessee Tech University

该项目通过建立到Internet2的专用10gbps连接和创建高速科学DMZ，促进了田纳西理工大学的国内和国际研究合作。新的网络基础设施使多个学院和研究中心的大量研究人员受益。它使数据驱动的研究领域包括下一代网络、网络安全、高性能计算、化学工程、生物学、高能物理、地球科学和土木与环境工程。升级后的连接使研究人员能够通过专用的研究连接以快速，安全和可靠的方式在内部和外部共享数据。Science DMZ为研究人员提供了特定于用例的分段资源（网络、磁盘空间和计算节点），并增加了部署孤立研究原型的自主权和灵活性。新的基础设施绕过田纳西理工大学的外围防火墙，同时与现有基础设施集成。高速数据传输节点（dtn）提供更快的数据传输到和从校园。网络设计为大多数建筑物的研究流量提供专用连接。部署在战略网络位置的几个PerfSonar节点报告实时网络和应用性能，使运营商能够优化网络流程。最后，这个新的基础设施将IPv6部署到校园。对部署前后的网络和应用程序性能的研究可以演示科学DMZ对科学工作流在性能、延迟和灵活性方面的影响。田纳西理工大学实施这个项目的经验可以为其他追求类似网络基础设施的大学提供指导。该奖项反映了美国国家科学基金会的法定使命，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。

This project facilitates national and international research collaborations at Tennessee Technological University by establishing a dedicated 10 Gbps connection to Internet2 and creating a high-speed Science DMZ. The new cyberinfrastructure benefits a large number of researchers across multiple colleges and research centers. It enables data-driven research in areas including next-generation Networking, Cybersecurity, High-performance Computing, Chemical Engineering, Biology, High-energy Physics, Earth Sciences, and Civil & Environmental Engineering. The upgraded connectivity enables researchers to share data both internally and externally in a fast, secure, and reliable manner over the dedicated research-only connection. The Science DMZ equips researchers with use-case specific segmented resources (network, disk space, and compute nodes) as well as increased autonomy and flexibility to deploy isolated research prototypes.The new infrastructure bypasses Tennessee Tech's perimeter firewall while integrating with the existing infrastructure. High-speed data transfer nodes (DTNs) provides faster data delivery to and from the campus. The network design provides dedicated connectivity for research traffic to most buildings. Several PerfSonar nodes deployed at strategic network locations report real-time network and application performance, allowing the operators to optimize network flows. Finally, this new infrastructure brings IPv6 deployment to the campus. A study of network and application performance before and after the deployment can demonstrate the impact of a science DMZ on science workflows in terms of performance, latency, and flexibility. The experience in implementing this project at Tennessee Tech can provide guidance to other universities pursuing similar cyberinfrastructure.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.
