<p>A receiver generates Explicit Rate Flow control information and includes it in flow-control messages sent to a transmitter. The receiver monitors the fullness of cell buffers used for temporarily storing received data cells, and monitors the direction and rate of change of the cell buffer fullness. Based on the cell buffer fullness information and the prevailing data transmission rate, the receiver calculates an updated data transmission rate and includes it in a flow-control message to the transmitter. Different calculations are used under different conditions of buffer fullness and its direction of change. The receiver also sets signalling bits in the flow-control message to indicate whether the data transmission rate should be changed by an incremental value, maintained at the same value, or reduced to a predetermined minimum value.</p> |
