Next: Traffic Trace Up: 31.3 The class TrafficGenerator Previous: Pareto On/Off CBR

A CBR object is embodied in the OTcl class Application/Traffic/CBR. The member variables that parameterize this object are:

Hence a new CBR traffic generator can be created and parameterized as follows:
        set e [new Application/Traffic/CBR]
        \$e set packetSize\_ 48
        \$e set rate\_ 64Kb
        \$e set random\_ 1

The setting of a CBR object's rate_ and interval_ are mutually exclusive (the interval between packets is maintained as an interval variable in C++, and some example  scripts specify an interval rather than a rate). In a simulation, either a rate or an interval (but not both) should be specified for a CBR object.
