public class traffic_OnOff

extends TrafficModel

implements TrafficPeriodic

This class describes an On/Off traffic model. On and off time intervals are exponentially distributed. It defines the following parameters:

On Time

Fixed length of on time (burst) intervals (second).

Off Time

Fixed length of off time (idle) intervals (second).

Average Sending Rate

Sending rate over the period of the on time plus off time (bps).

Packet Size

Size of packets (byte).
