James Aweya, Michel Ouellette, Delfin Y Montuno: TCP rate control with adaptive thresholds. Nortel Networks, Hunton & Williams, May 16, 2006: US07047312 (52 worldwide citation)

The TCP receiver's advertised window (i.e., the receive buffer of a TCP connection) limits the maximum window and consequently the throughput that can be achieved by the sender. Thus, the idea behind TCP rate control is to match the offered network load to the available resources by modifying at an ...
