Abstract

See full text

A method of operating in a network in which stations communicate over a shared medium is described. The method provides regularly repeated contention free intervals, CSMA communication during times outside the contention free intervals, and distributed control over the initiation and makeup of the contention free intervals to a plurality of stations so that any of the plurality of stations can independently initiate transmission within the contention free interval.
