Performance considerations on resolvable-contention-ring networks for fiber optic LANs

The objectives of this study are: (1) to show numerically the performance advantages of the resolvable-contention-ring (ReC-ring) in comparison with typical ring control methods like IEEE 802.5 token-ring, ANSI FDDI I token-ring, slotted-ring and contention-ring, and (2) to consider the possibility of using the priority mechanism of the ReC-ring for multimedia high-speed communications networks. The authors present a simple priority control mechanism based on the time-token scheme for multimedia communications of ReC-rings. The performance of the prioritized and nonprioritized ReC-rings is compared by computer simulation, and the priority mechanism presented is proved to have sufficient validity for multimedia communications networks
