摘要： 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.

摘要： A communications method for a shared-medium communications network having a plurality of stations connected by a first and second bus. The first bus is for data transmission in one direction and the second bus is for data transmission in an opposite direction. The method includes transmitting data between stations in slots. A station desiring to transmit requests the use of a slot by placing a request signal on the bus in a direction opposite to the desired direction of transmission. A slot is then used on a first request, first use priority except for a least one station which is allocated a slot without regard to the first request first use priority. This allocation provides for guaranteed bandwidth traffic.

摘要： An active queue management (AQM) process for network communications equipment. The AQM process is queue based and involves applying at a queue size threshold congestion notification to communications packets in a queue of a link via packet dropping; and adjusting said queue size threshold on the basis of the congestion level. The AQM process releases more buffer capacity to accommodate more incoming packets by increasing said queue size threshold when congestion increases; and decreases buffer capacity by reducing said queue size threshold when congestion decreases. Network communications equipment includes a switch component for switching communications packets between input ports and output ports, packet queues for at least the output ports, and an active queue manager for applying congestion notification to communications packets in the queues for the output ports via packet dropping. The congestion notification is applied at respective queue size thresholds for the queues, and the thresholds adjusted on the basis of the respective congestion levels of the queues of the output ports.

摘要： An active queue management (AQM) process for network communications equipment. The AQM process is rate based and involves applying at a rate congestion notification to communications packets in a queue of a link, and adjusting the rate of congestion notification on the basis of the difference between an arrival rate for the packets and a target capacity of the link. Network communications equipment includes a switch component for switching communications packets between input ports and output ports, packet queues for at least the output ports, and an active queue manager for applying congestion notification to communications packets in the queues for the output ports. The congestion notification is applied at respective rates for the queues, and the rates of congestion notification adjusted on the basis of the respective arrival rates of the packets for the queues of the output ports. The AQM process can be applied to a class based DiffServ architecture.
