I would like to ask the question on OnOffApplication, is related to the parameters MaxBytes and DataRate.
Assuming that the Simulation Stop time is 1000 seconds, MaxBytes = 1Gbytes.
When my DataRate is set to 10Mbps, the Tx / Rx bytes generated by the flowMonitor will stop at 1G.
However, when the DataRate is set to 100Mbps, the FlowMonitor's Tx / Rx bytes will stop at 44Mbytes.
Would you ask why is this? Is there anything relevant?
