This research note presents the results of a simulation study on the p
erformance of a new protocol suitable for use in a Gbit/s MAN. Perform
ance is simulated under a range of traffic types, access allocation al
gorithms, number of stations, and an overload condition. The results s
how that the protocol is very efficient, capable of achieving utilizat
ion close to 100% without stations incurring excessive mean message de
lays. It is also fair to almost all stations under conditions of under
load and overload.
