In August 2003, Tim Sigmon, Director of Advanced Technology at the University of Virginia (UVa), discussed the high-bandwidth networking capabilities supporting diverse research needs at UVa. With external OC-3 (155 Mbps) for Internet2 and DS-3 (45 Mbps) for dorm traffic, the campus backbone features multi-Gbps links, enhancing building connections. Research applications, such as the Legion grid-computing environment and BTeV collaboration in high energy physics, highlight the extensive use of Internet2. Future connectivity challenges with National Lambda Rail are also addressed.

High-bandwidth Networking at UVa Tim Sigmon Director, Advanced Technology University of Virginia August, 2003
Basic Network Connectivity • External connections • OC-3 (155 Mbps) for Internet2 and Internet • DS-3 (45 Mbps) for dorm traffic • Backup DS-3 • Campus backbone • Multi-Gbps backbone links (currently 2 Gbps) • Building connections are 1 Gbps or 100 Mbps • Building networks • Switched 10/100 Mbps and some 1 Gbps
Internet2 Uses at UVa • Internet2 use spans the entire range of research from the medical sciences to the physical sciences and engineering to the arts and humanities • Most researchers using Internet2 don’t even know they are using it since traffic destined to another Internet2 site is automatically routed over Internet2 • Two examples that “book end” UVa’s use of and need for high-bandwidth networking
Legion: An Early Internet2 Application • Computer Science researchers at UVa developed the Legion grid-computing environment • Legion was one of the first grid-computing environments deployed on Internet2 • Interconnected the national supercomputing centers as well as campus computing resources • Now commercialized as Avaki (www.avaki.com)
BTeV and High Energy Physics • BTeV experiment is an international collaboration that will use the Fermilab Tevatron collider to address a number of issues in particle physics (www-btev.fnal.gov) • Huge computational, storage, and networking needs that will drive us into the future • UVa physicists estimate that it will generate 2 petabytes of data each year (that’s after filtering its raw 1.5 terabytes/second rate!). • This data will be distributed and analyzed around the world, e.g., at UVa.
Future Issues • NLR – National Lambda Rail • MATP - Mid-Atlantic Terascale Partnership • Biggest issue: • NLR connectivity to Charlottesville
