Analysis of receiver window control in presence of a fair router

Receiver window control is a mechanism used to change the TCP advertised window so as to manipulate the bandwidth sharing of multiple TCP sessions. The research on receiver window control so far does not analyze behavior of the receiver window in the presence of packet drops at a fair router. In this paper, we analyze receiver window control in the presence of a modified RED-DT (random early detection with dynamic thresholds) router. We show that the receiver window control mechanism is goodput preserving and does not adversely impact competing traffic.
