Simulation study of the configuration dependent performance of a prioritized, CSMA broadcast network

Conference ·
OSTI ID:5241903
A high-speed (50 megabits per second), multinode (20 nodes), prioritized, CSMA broadcast network has been studied via a discrete event simulation. The results imply that, for those networks that employ some kind of random persistent CSMA versus CD prioritized-channel access, network performance is affected by perturbations in the network geometry; that is, the performance of a CSMA broadcast network can be degraded significantly when that network is extended to include remotely situated nodes. The results are obtained for and comparisons made of two radically different contention mechanisms, the mechanism employed in the Hyperchannel of NSC and an Ethernet-like scheme. 10 figures.
