Abstract :
The authors propose a mechanism for implementing priorities in an IEEE 802.6 (DQDB) subnetwork of a metropolitan area network. The mechanism allows the priorities to be preemptively multiplexed among each other, thus, always guaranteeing maximum bandwidth to the highest priority traffic whenever it is requested. The proposed mechanism responds fast in the presence of high priority traffic and it takes full effect within at most one round trip propagation delay
