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
