ABSTRACT:
The rate at which a node transmits data is modified dependent on the receive rate by selecting one of a plurality of predetermined quantum values dependent on the difference between the number of bytes received and the number of bytes transmitted. An offset equal to the difference between the number of bytes transmitted and the number of bytes received is compared to a predetermined threshold value. A predetermined quantum value is selected dependent on the result of the comparison. Rate shaping is applied to the transmit data by halting data transmission for an inter-gap interval dependent on the selected quantum value.
