CC* Networking Infrastructure: A Science DMZ to Enable Friction-Free Scientific Data Workflows

堪萨斯大学（KU）正在为研究科学家实施每秒100千兆位（Gbps）的科学DMZ网络，该网络为专用的科学研究流量工作流提供了单独的网络。 这为研究计算中心（CRC），冰盖遥感中心（CReSIS），基因组测序核心（GSC），生物多样性研究所（BI）以及显微镜和分析成像实验室（MAI）的许多研究项目提供服务。 项目团队由领域科学家、计算机科学家和KU信息技术管理人员组成。 这些不同科学领域的共同主题是加强外部机构合作、数据共享、远程数据传输和教育推广。基础设施升级是网络架构的基础，该架构以专用的100 Gbps研究网络骨干为锚，专门用于优先考虑研究数据流，并且易于扩展以添加新连接。 这种设计是仿照能源科学网络（ESnet）成功的科学DMZ网络架构，该架构已在100多所大学复制。 该项目的地址？最后一英里？网络瓶颈和园区企业设计的网络架构。 目前的网络设计对校园企业网络上的研究数据流量设置了障碍，这些网络竞争有限的网络带宽。 该项目提升了KU的科学研究数据以更高的速度传输，从而加强了跨学科和外部合作，并使当前和未来的科学访问能够无摩擦网络。

The University of Kansas (KU) is implementing a 100 Gigabit per second (Gbps) Science DMZ network for research scientists which provides a separate network for dedicated scientific research traffic workflows. This serves many research projects at the Center for Research Computing (CRC), the Center for Remote Sensing of Ice Sheets (CReSIS), the Genome Sequencing Core (GSC), the Biodiversity Institute (BI), and the Microscopy and Analytical Imaging laboratory (MAI). The project team is composed of domain scientists, computer scientists, and KU Information Technology administration. The common themes uniting these diverse scientific areas are enhanced external institutional collaboration, data sharing, remote data transfer, and educational outreach.The infrastructure upgrades are the foundation for a network architecture that is anchored by a dedicated 100 Gbps research network backbone devoted to prioritizing research data flows and is easily extensible for adding new connections. This design is modeled after the successful Science DMZ network architecture from the Energy Sciences Network (ESnet), which has been replicated at more than 100 universities. The project addresses the ?last mile? network bottleneck and the campus enterprise designed network architecture. The current network design places barriers on research data traffic on campus enterprise networks that compete for limited network bandwidth. This project elevates scientific research data at KU to transfer at higher speeds, which enhances interdisciplinary and external collaborations, and enables current and future scientific access to friction-free networks.
