Abstract :
In the letter we formulate an exact analytic model for throughput in multichannel CSMA/CD systems. A salient feature of this model is that the normalised end-to-end propagation delay remains fixed as the number of channels is changed. As a result, it is shown that, under a Poisson arrival process, the optimum number of channels is dependent on the input load. This and other results are in sharp contrast to the conclusion obtained from previous approximate models.
