Real-time study of a high performance protocol for local/metropolitan ring networks

Abstract

We propose a new group of slotted ring protocols called REALNET. In REALNET networks the ring access scheme, traffic control and management, and slot allocation for voice and data cycles are made highly adaptive. We analyze, simulate and compare different REALNET networks which use different methods for their cycle alternation strategy. The results show that REALNET networks that use prediction satisfy strict voice delay requirements, allow small percentages of voice packet loss for a large number of active voice stations, as well as providing higher bandwidth utilization, and giving lower delays and higher throughputs for data packets when compared to other integrated services protocols.<>
