<p>A data communication system (10) allocates use of a common data communication medium (14) shared by a plurality of stations (12A-12D). During each transmission cycle, the communication medium (14) carries data packets of varying priority which each station (12A-12D) receives. The stations (12A-12D) are allocated use of the communication medium (14) during one or more priority intervals as a function of the priority of the packet which the station is ready to transmit. Each station (12A-12D) is synchronized to a transmission cycle period which is divided into subperiods. Certain types of packets are relegated to transmission and reception within predetermined subperiods.</p> |
