Status Report on US networks at the Turn of the Century
Les Cottrell – SLAC & Stanford U.www.slac.stanford.edu/grp/scs/net/talk/us-net-status-2000.htm
Presented at CHEP00, Padua Italy, February 9, 2000

Overview• U.S. Networks:
– Internet 2
– Federal networks, in particular ESnet
– Commercial
• Performance seen from U.S.: – Compare Internet2 vs. ESnet vs Commercial
Internet 2• A project by consortium of universities (UCAID) to:
– foster development of advanced internet applications;
– foster development internet technology itself;
– provide a high performance network for general research.
• Not a Government project; no direct Federal subsidy
• Not a network itself:
– The NSF-funded vBNS evolved into a ‘pre’ Internet-2 backbone;
– Abilene is the UCAID-sponsored Internet-2 backbone.

Internet 2 Membership• Internet 2
– 170 universities– ~ 10-12 non-university members including CERN– other networks can connect as affiliates;– U.S. National Labs are not members of UCAID:
• National Lab Internet-2 participation assumed thru ESnet
Internet 2 AUP• Internet 2 Acceptable Use Policy (AUP)
prohibits transit traffic between affiliates:– ESnet site with Internet-2 member site is ‘OK’ to use I2;– ESnet site to other affiliated network site via Internet-2
backbone is NOT permitted.
• Internet 2 AUP also prohibits “commodity” internet traffic!– Traffic to another Internet-2 site routed via Internet-2
backbone;– Traffic to a non-Internet-2 site must be routed via
commercial ISP;– Requires universities to have a separate Internet
connection for commodity traffic.

• 5500 miles deployed, backbone operates at speeds up 2.4Gbps. Interconnections at 155 & 622Mbps
