ABSTRACT:
A station for a network using a DQDB communications protocol. A counting unit for maintaining an erased count of erased slots, an erasing unit for determining, erasing and outputting slots received on a transmit bus which have been used to transmit data to and have been received by an intended destination on the transmit bus are used. The erased slots are thereafter available for use by stations for data transmission on the transmit bus, and for determining if the erased count is greater than a predetermined value when a request for a slot is received by the station on a request bus and for erasing the request when the erased count is greater than the predetermined value. The erase count may be incremented by the station when a slot is erased by the station. Alternatively the erase count of a station may be incremented only when the station uses an erased slot to transmit data to another station. The counting unit may also include a high priority erase counting unit for maintaining the erase count on the basis of received high priority requests and erased slots used by the station to satisfy a high priority request, and a low priority erase counting unit for maintaining a low priority erased count of erased slots which may be used by succeeding stations to satisfy a low priority request for a slot.
