Enabling Users to Control their Internet
summary
A receiver-side system called CRAB estimates downlink capacity and per-flow demand, computes max-min weighted fair rates, and throttles incoming flows on Linux and Linksys WRT3200ACM routers without ISP or sender changes. It probes bandwidth by briefly increasing a random saturating flow, doubling probe increments on success, waits multiple RTTs for senders to react, and reclaims unused share. Evaluations with a 30 Mbps bottleneck show a 5:1 video:bulk policy giving ~25 Mbps to video and achieving 2× lower page load times and 3× higher video quality.
