High-bandwidth Networking
at UVa

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
