CC-NIE Network Infrastructure: Improving an existing science DMZ

Research Computing在为科罗拉多大学博尔德分校（University of Colorado Boulder）的研究小组部署数据移动服务方面一直处于领先地位，例如Globus Online在一个独立的网络RC-DMZ上，该网络专门用于高性能应用程序和研究数据传输。该项目对RC-DMZ进行了重大改进，以提高可管理性、可靠性和带宽。由于科学、技术、工程和数学（STEM）领域的大量研究是高度数据密集型的，观测和模拟数据收集在数十或数百TB (TB)，并且很快会增长到PB (PB)，因此这已经成为必要。最近的“校园桥接”工作组报告也表明，需要继续投资校园网络功能。RC- dmz的升级包括：*商品和研究流量之间的物理分离通过两个新的边界路由器*改进的网络设计通过增加冗余和带宽改进到20千兆*主动，集成的性能测量*安全和流量监控*实验软件定义/ OpenFlow网络改进现有的RC- dmz是研究计算（RC）之间的合作，计算机科学（CS）部门，物理，分子，细胞和发育生物学（MCDB）、国家冰雪数据中心（NSIDC）和信息技术办公室（OIT），并与其他部门和研究所协商。网络的改进使更好的数据共享，并为所有科罗拉多大学博尔德分校的研究人员改善了对本地、区域和国家计算和数据资源的访问。

Research Computing has been a leader in deploying data movement services to research groups at the University of Colorado Boulder such as Globus Online on a separate network, the RC-DMZ, which is dedicated to high-performance applications and research data transfers. This project implements significant improvements to the RC-DMZ in order to increase the manageability, reliability and bandwidth. This has become necessary driven by the large amount of research in Science, Technology, Engineering and Mathematics (STEM) that is highly data intensive, with observational and simulation data collections in the tens or hundreds of terabytes (TB), and soon growing to petabytes (PB). The recent "Campus Bridging" task force report also demonstrates the need for continued investment in campus networking capabilities. The upgrades to the RC-DMZ include:* Physical separation between commodity and research traffic through two new border routers* Improved network design by adding redundancy and bandwidth improvement to 20 Gigabit* Active, integrated performance measurements* Security and traffic monitoring* Experimental software defined / OpenFlow NetworkingImproving the existing RC-DMZ is a collaboration between Research Computing (RC), the departments of Computer Science (CS), Physics, Molecular, Cellular and Developmental Biology (MCDB), the National Snow and Ice Data Center (NSIDC), and the Office of Information Technology (OIT) in consultation with other departments and institutes. The network improvements enable better data sharing, and improved access to local, regional and national computational and data resources for all of CU Boulder's researchers.
