摘要：

Simulation is used to estimate the performances of MAC protocols derived from CSMA/CD, and operating in local area networks comprising several parallel broadcast channels. The influence of possible protocol and system alternatives on the network performance is discussed, based on results of the packet delay average, variance, mean square, coefficient of variation, and histogram, as well as the packet rejection probability due to lack of buffer space. The delay incurred by multipacket messages is also estimated, comparing the single channel to the multichannel option. Numerical results clearly indicate that the multichannel option can provide remarkable reductions in both the packet delay average and variance, even when stations are only able to simultaneously receive from a subset of channels.
