A modified QA (queued arbitrated) protocol for improving performances in DQDB MAN

The QA (Queued-Arbitrated) protocol of the DQDB has several drawbacks such as unfairness .of access opportunities and inefficiency of priority scheme in the multi-priority environment. In this paper, we present a modified version of the basic distributed queueing algorithm to solve these problems. Simulation results indicate that the proposed strategy… CONTINUE READING
