Some Recent Progress Some recent progress More at the SIG Available bandwidth Publishing More at the SIG Autoshooting case study

Available Bandwidth Estimator (ABwE) Tool under development by SLAC/Rice Jiri Navratil Part of the DoE/SCIDAC INCITE project Light weight 60 packets in 1 second Iperf 35,000 packets/s for 10-20 seconds No need to tune windows/streams Replace iperf in test engine FreeBSD version created for Abilene Backbone Measurement Infrastructure
