ABSTRACT:
Delay times are modified in Ethernet network devices by adding a slot time to the minimum interpacket gap (IPG) interval between uninterrupted consecutive transmissions by a network station. If a network station transmits a data packet and has another data packet to send, modified delay time prevents the station from contending for access of the media, enabling other stations having data to transmit to attempt access on the media. If a collision occurs during the transmission of a second successive data packet, the network station uses a modified collision arbitration and automatically sets the collision delay interval to zero for the first access attempt. If another collision occurs during the access attempt, the collision interval is calculated according to the truncated binary exponential backoff algorithm.
