A receiver may be adapted to prevent overflow or underflow of its data storage by generating a transmit rate value as a feedback to the sender. Speed adjustments are performed periodically with a fixed time period denoted by Dt. Transmission rates are explicitly 0, Max/2, and Max. The receiver queue is itself drained at a rate R that at any time satisfies 0<=R<=Max. The level of occupancy of the receiver storage queue is denoted by Q. The maximum capacity of the receiving queue is designated Qmax, so at any time, 0<=Q<=Qmax. Two thresholds T1 and T2 (with 0<T1<T2<Qmax) of levels of the receiver queue value Q are determined. A transmit rate is then determined by the level of the receiver queue Q compared to the thresholds. The transmit rate feedback value achieves the desired goal of avoiding overflow and, once the value of Q has been positive at least once, avoiding underflow.
