The Perl script gc.pl executes one run of the ssfnet simulator, either on a fixed bottleneck bandwidth topology or a scaled one. Parameters for the run are passed to it on the command line, see the scripts comments. The topology is the dumbbell, described in the associated paper. In the 'fixed' topology one increases the number of TCP sessions without increasing any link bandwidths. In the 'scaled' topology the bandwidth of the bottleneck link is n*1.5e6 bps, where n is the number of TCP sessions. The clock resolution in the DML file is good up to about 60,000 sessions. In the unlikely need of running larger models than that, one should multiple the frequency parameter in the build script by a factor of 10.Download all files:
