CC*IIE Networking Infrastructure: A Performant and Reliable Science DMZ for National and International Collaboration

芝加哥大学(UChicago)建立了一个高速的科学非军事区网络，其中包括到研究和教育网络的100Gbps上行链路。该网络为研究人员提供了以极高的速度进行国内和国际协作所需的带宽。最初的实验构建是以非冗余的方式完成的，这意味着一个单一的故障或中断就有可能影响依赖于科学DMZ的每个项目。此外，多个项目已经证明，高带宽需求将迅速挤占可用的单一100Gbps上行链路。为了解决这些风险和担忧，UChicago正在其海德公园主园区和芝加哥市中心的一个地点之间建设冗余密集波分复用(DWDM)系统。该系统包括第二个支持100Gbps的路由器，为UChicago？S科学DMZ网络提供额外的容量和弹性。建成后，该系统将为研究人员提供高度可用的、极高容量的网络基础，使他们能够最大限度地提高科学生产率。将受益的科学项目包括：-ATLAS在CERN大型强子对撞机(LHC)上的协作-Bionimbus-为管理和分析基因组数据而设计的开放科学数据云项目-Kavli宇宙物理研究所(KICP)推进对暗物质和暗能量性质的研究-南极望远镜(SPT)协作？宇宙微波背景辐射(CMB)调查-城市计算和数据中心(UrbanCCD)与芝加哥市政府合作设计和实施其下一代数据分析平台。

The University of Chicago (UChicago) has built a high-speed Science DMZ network that includes a 100Gbps uplink to Research and Education networks. This network provides researchers with the bandwidth required to collaborate both nationally and internationally at extremely high speeds. The initial experimental build was completed in a non-redundant fashion, which means that a single failure or disruption has the potential to impact every project dependent on the Science DMZ. Further, multiple projects have demonstrated high-bandwidth needs that will quickly congest the singular 100Gbps uplink available.To address these risks and concerns, UChicago is building a redundant Dense Wave Division Multiplexing (DWDM) System between its main Hyde Park campus and a location in downtown Chicago. This system includes a second 100Gbps capable router that provides UChicago?s Science DMZ network with additional capacity and resiliency. Upon completion, the system will provide researchers with a highly available, extremely high-capacity network foundation that enables them to maximize their scientific productivity. Amongst science projects that will benefit are: - ATLAS collaboration at the CERN Large Hadron Collider (LHC)- Bionimbus - Open Science Data Cloud Project designed for managing and analyzing genomic data- The Kavli Institute for Cosmological Physics (KICP) advancing research on the nature of dark matter and dark energy- The South Pole Telescope (SPT) collaboration ? a survey of cosmic microwave background (CMB) radiation- The Urban Center for Computation and Data (UrbanCCD) partnering with the City of Chicago to design and implementation its next generation data analytics platform.
