A Traffic Trace object is instantiated by the OTcl class
Application/Traffic/Trace.
The associated class Tracefile is used to enable multiple
Traffic/Trace objects to be associated with a single trace file.
The Traffic/Trace class uses the method attach-tracefile to associate
a Traffic/Trace object with a particular Tracefile object.
The method filename of the Tracefile class associates a trace file
with the Tracefile object.
The following example shows how to create two Application/Traffic/Trace objects,
each associated with the same trace file
(called "example-trace" in this example).
To avoid synchronization of the traffic generated,
random starting places within the trace file are chosen for
each Traffic/Trace object.
set tfile [new Tracefile]
$tfile filename example-trace
set t1 [new Application/Traffic/Trace]
$t1 attach-tracefile $tfile
set t2 [new Application/Traffic/Trace]
$t2 attach-tracefile $tfile
