Abstract :
A mechanism is proposed for implementing priorities in an IEEE 802.6 (DQDB) distributed queue dual bus subnetwork of a metropolitan area network. The mechanism allows the priorities to be preemptively multiplexed among each other, thereby always guaranteeing maximum bandwidth to the highest priority traffic whenever it is requested. The proposed mechanism takes full effect in less than one round trip delay between two neighboring active stations with different highest internal priority levels
