[ns] Problem running fair qeueing (FQ)

[Abdul Aziz Mustafa <amustafa@cse.unsw.edu.au>]

Hi Ns users,

I am trying to simulate fair queuing by changing the queue type from DropTail to FQ but

encountered following error message during runtime.


ns: _o172 unknown-flow 2 3 0: can't read "drpT_": no such variable
    while executing
"$q drop-target $drpT_"
    (procedure "_o167" line 12)
    (FQLink new-flow line 12)
    invoked from within
"$fq_ new-flow $src $dst $fid"
    (procedure "_o172" line 3)
    (Classifier/Hash/Fid/FQ unknown-flow line 3)
    invoked from within
"_o172 unknown-flow 2 3 0"


Btw, when I set the queue type to SFQ (stochastic)it works fine. Am I missing something ?


Thanks in advance.

Aziz
