Re: [ns] Passing Traffic to a Queue

[Alefiya Hussain <alefiyah@catarina.usc.edu>]

It is possible to pass traffic to a queue without attaching it to a node. 
You can do this in very easily in Tcl code. 

what you would need to do is as the following:
set q_ [new Queue/DropTail]  
$FromWhereTrafficcomeToTheQueue target $q_
$q_ target ["where you want you queue to send the traffic]

i hope this helps
