public class traffic_ExpOnOff

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

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

Off Time

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

Burst Rate

Sending rate during on time (bps).

Packet Size

Size of packets (byte).
