Jitendra Padhye and Sally Floyd, ACIRI
This talk describes a tool for characterizing the TCP behavior of
a remote host on the Internet. The specific goal in building this
tool was to answer the question, "What fraction of web servers use
NewReno instead of Reno or Tahoe TCP congestion control mechanisms,
for TCP connections with non-Sack-enabled clients? The more
general goal was to provide a tool for efficiently probing the TCP
congestion control behaviors of remote hosts in the Internet. We
report on both the tool and our experimental results.

About the Presenters
Jitendra Padhye and Sally Floyd are both research scientists
at ACIRI, the AT&T Center for Internet Research at the International
Computer Science Institute. Sally
has worked on a range of congestion-control-related issues,
including TCP congestion control mechanisms, active queue management,
and Explicit Congestion Notification (ECN). Jitu recently received
his Ph.D. from the University of Massachusetts at Amherst, and his
work includes equation-based congestion control and
characterizations of TCP throughput.
