http://www.cs.cmu.edu/~istoica/csfq/ A quick check of the ns research and contributed code pages on the mash server didn't turn up a mention of or link to this, so I thought I'd point its existence out. Looks like simulations of traffic conditioning at network edges; for ns 2.1b2. Haven't tried the code. Cheers, L. <[email protected]>PGP<http://www.ee.surrey.ac.uk/Personal/L.Wood/>
