Abstract
Interpacket delay times are modified in full-duplex Ethernet network devices by calculating for each network station a delay interval based on a time to transmit a data packet at the network rate and a calculated time to transmit the data packet at a desired transmission rate. The network station waits the calculated delay time following a packet transmission before transmitting the next data packet, ensuring that the overall output transmission rate of the network station corresponds to the assigned desired transmission rate. The desired transmission rate is received as a media access control (MAC) control frame from a network management entity, such as a switched hub. Hence, each network station operates at the desired transmission rate, minimizing the occurrence of congestion and eliminating the necessity of PAUSE frames.
