Abstract
A network interface for a shared gigabit Ethernet network selectively modulates an interpacket gap interval following a burst transmission in order to establish a rotating priority arrangement with network stations on the gigabit network. A network station includes a programmable burst timer that counts a burst interval corresponding to a negotiated bandwidth. The network station having accessed the media continues to transmit data packets so long as data is available in a transmit buffer, and the burst timer has not expired. Each data packet within the burst is transmitted after waiting a minimum interpacket gap interval of 96 bit times. Following the burst transmission, the network interface waits a modified delay interval equal to the minimum interpacket gap plus a multiple number of slot times related to the number of stations on the network. The modified delay interval is decremented by a slot time each time the network station detects a burst transmission by another network station. Each network station thus transmits a burst of data packets according to a negotiated bandwidth, and minimizes the number of encountered collisions by deferring to other network stations following…
