Description
Analytical and simulation performance evaluation results
are presented on the effects of message segmentation and
the validity of the Independence Assumption when applied
to analytically modeling tandem node computer networks.
Simulation results indicate that increasing message
segmentation threshold will increase the network traffic
intensity and consequently the total packet delay. Simulation
and analytical results for total packet delay compared
well only at low traffic intensities. At higher
traffic intensities the discrepancy is due to the
Independence Assumption since it does not account for the
increasing dependency of interarrival times and service
times as packets are made to wait at the nodes.
