Abstract
A flow of data (26) is regulated in a communication system (20). A data rate is established in each of a data source (24) and a data sink (28). The data (26) is transmitted by the data source (24) and written into a buffer (32) at the source data rate, then read from the buffer (32) and received by the data sink (28) at the sink data rate. The level (62) of data (26) in the buffer (32) is monitored, and a rate-control signal (74) is dispatched to either the data source (24) or sink (28) when it is determined the buffer data level (62) is decreasing or increasing while at a lower or upper data-level threshold (66, 68), respectively. One of the data rates is adjusted in response to a rate-control signal (74).
