ABSTRACT:
A communications system includes a network that is coupled to a number of terminals, at least some of which are capable of audio or other forms of real-time interactive data communications over the network. Each of the terminals includes a network adapter that is capable of detecting a collision with another terminal on the network. If a collision is detected, transmission of a data frame is aborted, and a backoff time delay is selected. The backoff time delay is selected from a group of delay periods that vary at a rate different than exponentially with a number of collisions. The group of one or more delay periods can contain delay periods that increase linearly with the number of collisions, delay periods that increase according to some power of n, where n is the number of collisions, or a delay period that is selected at random based on a predetermined mean backoff delay. Alternatively, the selected backoff time delay is selected from a group of delay periods that increases exponentially with the number of collisions, but with a maximum value set that is less than the maximum set according to conventional backoff algorithms.
