The performance of an enhanced DQDB protocol with Bandwidth Balancing (BWB) and Multiple Requests Outstanding (MRO) under sustained overload is examined by means of simulation. It is demonstrated that MRO may provide a desired bandwidth apportionment without using BWB, for a very specific case of concentrated sources; otherwise. MRO cannot be used without BWB to obtain the desired bandwidth allocation. When used together with, and in the same ratio as, the BWB, MRO speeds up the convergence towards the steady state bandwidth apportionment intended by BWB. © 1993 Butterworth-Heinemann Ltd.
