CC-NIE Networking Infrastructure: Extensible Cyberinfrastructure for Enhancing Extreme-Data Science (EXCEEDS)

从癌症基因组学到射电天文学再到脑成像，许多当前研究项目的数据需求远远超出了大多数大学的处理能力。由于研究人员无法快速转移他们的庞大数据集，这些领域和其他重要领域的进展受到了极大的阻碍。问题不仅在于底层链路的带宽，还在于整个网络架构，这限制了网络管理员部署新功能的能力。增强极端数据科学的可扩展网络基础设施（exceed）项目通过提高加州大学伯克利分校支持极端数据科学的能力，加速了该校的科学发现。正在实施的基础设施改进包括：将边界带宽增加到100Gb/s，安排从伯克利到加州大学圣地亚哥分校的端到端100Gb/s数据路径，建立现代科学非军事区（DMZ）架构，并在这个新的高速网络上部署具有100Gb/s能力的Bro入侵检测系统(IDS) -目前是伯克利安全架构的关键部分。在短期内，基础设施的改善将加速伯克利在几个科学领域的进步，最显著的是癌症基因组学，但也包括射电天文学和其他领域。从长远来看，对更可扩展的校园架构的研究将导致更灵活的网络设计，从而促进全国校园的科学进步。

The data requirements of many current research projects -- ranging from cancer genomics to radio astronomy to brain imaging -- have far outstripped what most campuses can handle. Progress in these and other important fields is significantly hampered by the inability of researchers to rapidly transfer their extremely large datasets. The problem lies not only in the bandwidth in the underlying links, but also in the overall network architecture which limits the ability of network administrators to deploy new functionality.The Extensible Cyberinfrastructure for Enhancing Extreme-Data Science (EXCEEDS) project is accelerating scientific discovery at the University of California, Berkeley by improving the university's ability to support extreme-data science. The infrastructure improvements being implemented include: increasing border bandwidth to 100Gb/s, arranging for an end-to-end 100Gb/s data path from Berkeley to the University of California at San Diego, establishing a modern Science Demilitarized Zone (DMZ) architecture, and deploying a 100Gb/s capable Bro Intrusion Detection System (IDS) -- currently a critical piece in Berkeley's security architecture -- on this new high-speed network. In the short run, the improved infrastructure will speed progress at Berkeley in several scientific areas, most notably cancer genomics but also in radio astronomy and other fields. Longer term, the research on more extensible campus architectures will lead to more flexible network designs that can enhance scientific progress on campuses throughout the nation.
