Simulation results
We evaluated the queueing performance of a CDPD network with various input traffic types.
The plots show the average delays for:
- actual traffic data (graph A)
- traffic trace generated by our ON/OFF source (graph B)
- Poisson source (graph C).
Assumption: infinite buffer size.
The queueing performance of the traffic generated by an ON/OFF source (graph B) is closer to the network performance observed with collected traffic data (graph A).
This is to be expected, since ON/OFF sources reflect the bursty nature of the genuine network traffic better than Poisson sources (graph C).
