Hi All, Here is the error I get when I try to run test01.tcl and test02.tcl of ns-OBS under NS-2.33, NS-2.28. I am using fedora 8 as OS.

[ns] SFQ in Wireless
Hi all, Do you have any experience in using SFQ instead of DropTail/PriQueue in wireless link? When I set ifq as Queue/SFQ or Queue/FQ when I run the simulator it returns Segmentation Fault. Do I need to set any particular parameter when I use SFQ? Based on NS manual two configuration parameters (i.e. maxqueue_ and buckets_) are important for SFQ and in this regard both have default values. I would be grateful for any suggestions. Thanks Fariborz

[ns] Handover1.cc Mobility code
hi all,
i have a code of handover1.cc when creating handover module
/*
* Creates a handover module
*/
Handover1::Handover1() : Handover(), connectingMac_(-1), scanTimer_(0)
{
bind (case_, case_);
bind (confidence_th_, confidence_th_);
}
My question is : where can i find the value of confidence_th_ , is it a
argument or given in an other class ?
thanx
Re: [ns] Problem with tracing SCTP Agent Trafic
I tried the two ways but it didn't work :(
Do you have other propositions?
2009/5/15 najla najla.tr...@cert.mincom.tn
I have already faced this problem when working on SCTP. I think that you
must add the command set-multihome-core with its arguments (as mentioned
in the Ns documentation)
Good luck

Objet : [ns] Problem with tracing SCTP Agent Trafic
hi to all,
I'm trying to trace SCTP trafic,to explore the cwnd and rto values.
Unfortunately when I added the suitable lines to trace the agent I got this
error.
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
_o51: no target for slot 0
_o51 type: Classifier/Hier
I need your help to resolve this problem.Do you have any advice?
Below are the lines that I've added to trace agent trafic
set sctp0 [new Agent/SCTP]
$ns_ multihome-attach-agent $sgsn $sctp0
$sctp0 set fid_ 0
$sctp0 set debugMask_ -1
$sctp0 set debugFileIndex_ 0

Hi, I have to trace SCTP trafic I have used this script but it didn't work : set trace_ch [open trafic.sctp w] $sctp0 set trace_all_oneline_ 1 $sctp0 trace cwnd_ $sctp0 attach $trace_ch Do you have any idea ?? thanks
Re: [ns] Error in creating new agent
I got same this error message when i run the tcl script as follow:
[u...@localhost ~]$ ns ibrahim.tcl
ns:
[code omitted because of length]
: invalid command name Agent/Ibrahim
while executing
Agent/Ibrahim set packetSize_ 64
[u...@localhost ~]$
this happened because of the name of the class in the linkage part not
correct, i mean in the .cc file you should check the spelling in this line
for example: IbrahimClass() : TclClass(Agent/ibrahim) {} , the error
happened because of the Agent/ibrahim ibrahim is not correct name it
must be Agent/Ibrahim. In your case must be Agent/MyClusAgent so check
the spelling name.
I hope this help you.

the strange thing is as soon as I make this change in ns-default.tcl. All
other tcl files also stop working and the error I listed before is
returned.
Any help inthis regard will be highly appreciated.
Thanks Regards,
