  • determining a priority level of a data packet to be transmitted;

    determining non-activity on the media;

    determining a wait time following the determination of non-activity on the media to transmit the data packet, the wait time being a function of the priority level of the data packet to be transmitted and a current priority of the network station among the network stations on the network for that data priority level; and

    transmitting the data packet on the medium after the determined wait time following the determination of non-activity on the media, if there is currently no activity on the media;

    further comprising the step of the network stations adjusting their wait times in response to collision identification signals that identify the levels of priority of data packets that collided on the media.
