Variable contention transmission media access based on idle waiting time

摘要

A facility having particular data to transmit over a transmission medium, contends for access to the medium by transmitting a jamming signal over the transmission medium for a particular duration of time that is a small fraction of the amount of time that the facility had to thus far wait to so contend. If the transmission medium is found to be idle at the expiration of that time, then the facility accesses the medium. Otherwise, the facility waits until the transmission medium again becomes idle and then re-contends for access.
