CC-NIE Networking Infrastructure: 100 Gb/s Science DMZ

加州大学圣克鲁斯分校（UCSC）拥有多个领域的领先研究中心，包括天体物理学、基因组学、地球和行星科学以及粒子物理学。作为研究项目中计算组件的积极采用者，这些中心都对高性能网络有着当前和不断增长的需求。这些研究活动涉及跨网络传输大数据，目前受到UCSC与区域，国家和国际研究网络连接的限制。该项目的动机是重新构建UCSC的研究网络，使其针对这些高性能科学应用进行优化。为了更好地支持这些大数据研究活动，UCSC在UCSC网络中添加了一个针对高性能应用进行优化的科学DMZ组件。科学DMZ是校园网络的一部分，它将这些大科学数据流与生产网络流量隔离开来。UCSC正在提供从科学DMZ到区域，国家和国际研究网络的100 Gb/s外部连接，以及支持这些项目的计算基础设施的10 Gb/s。UCSC正在部署增强的测量和监控功能，以确保新基础设施的最佳使用，以及实验性的OpenFlow技术，以实现为这些用户提供增强服务的实验。为了确保研究人员能够充分利用新的服务，UCSC专门的网络工程人员作为研究人员和中央校园IT人员之间的桥梁，以确保研究人员充分利用新的基础设施。

The University of California Santa Cruz (UCSC) is home to leading research centers in a number of areas, including astrophysics, genomics, earth and planetary science, and particle physics. Being aggressive adopters of computational components in their research programs, these centers all have current and growing requirements for high-performance networking. These research activities involve the transfer of big data across the network, and are currently limited by UCSC's connectivity to regional, national, and international research networks. The motivation for this project is to re-architect UCSC's research network so that it is optimized for these high performance scientific applications.To better support these big data research activities UCSC adds a Science DMZ component to the UCSC network that is optimized for high-performance applications. The Science DMZ is a portion of the campus network that segregates these big science data flows from production network traffic. UCSC is provisioning 100 Gb/s external connectivity from the Science DMZ to regional, national, and international research networks, and 10 Gb/s to the computational infrastructure supporting these projects. UCSC is deploying enhanced measurement and monitoring capabilities to ensure optimal use of the new infrastructure, and the experimental OpenFlow technology to enable experiments in enhanced services for these users. To ensure researchers are able to make optimal use of the new services UCSC dedicates network engineering personnel to act as a bridge between the researchers and central campus IT staff to ensure researchers make maximal use of the new infrastructure.
