Safa,
<div><br>
</div>
<div>I'm not sure what you mean by output, so I'll lightly cover all bases. </div>
<div><br>
</div>
<div>The output to standard out that you are showing below is for warnings and errors. The code is now running with CoDel patched and working I am assuming based on what you've said. Exactly what the illegal sack block means, I don't know off hand, I'd look
through the TCP code for that message and backtrack from there. I'd start looking in <span style="font-family: monospace; text-align: left; ">ns/tcp/tcp-full.{cc,h}. </span></div>
<div><br>
</div>
<div>The nam output is commented out in the CoDel.tcl file from the Pollere website, so it won't be active. See lines 380-384 in CoDel.tcl. I have never used nam much and honestly have yet to see the real value. </div>
<div><br>
</div>
<div>The true output files in ns are trace files. Trace files can be attached to links and possibly other ns objects, memory is a bit foggy here. CoDel.tcl creates it's trace files in lines 388-394 on a link between nodes $n0 and $n1. The main output of this
script is the file /tmp/<a href="http://f.tr">f.tr</a> the format of which is explained here <a href="http://nsnam.isi.edu/nsnam/index.php/NS-2_Trace_Formats">http://nsnam.isi.edu/nsnam/index.php/NS-2_Trace_Formats</a></div>
<div><br>
</div>
<div>
<div>OK for now,<br>
Jp </div>

</div>
your help will be greatly appreciated. I have tried to triangulate the problem. With more packmime connections I get more illegal SACK bllock warnings. Can you or anyone on the CoDel list tell me what output is expected after runniing the TCL script?<br>

I ran codel after PATCHING it into the ns2 simulator. Then I ran the following command
<br>
<br>
./ns codel.tcl 4 5 0 100Mb -1 5<br>
<br>
However there was no nam output and I get the following result. Would you please tell if Codel.tcl even has nam output or not? And what are these warnings for? Also how the result is to be interpreted?<br>

<div>I have followed the instructions to build ns2. Let me give you a stepwise description of what I have done.<br>
<br>
</div>
I have downloaded and installed ns2 from the following source<br>
<a href="http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download" target="_blank">http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download</a><br>
<br>
</div>
After that I downloaded the whole master repository as a zip and unzipped it<br>
<a href="https://github.com/dtaht/ns2" target="_blank">https://github.com/dtaht/ns2</a>
<br>
<br>
</div>
Now could you please give me a stepwise description as to how I should proceed from here. I have been trying to run the codel.tcl directly by
<br>
ns codel.tcl<br>
</div>
after going to ns2-master directory without success. I keep getting the error:
<div><br>
<br>
ftps 1 webrate 0 cbrs 0 bw 3000000.0 filesize 10000000 reverse 0<br>
accessdly 20 bneckdly 10 realrtt 100 bneckbw 3000000.0<br>
invalid command name "Queue/CoDel"<br>
while executing<br>
"Queue/CoDel set target_ $target"<br>
(file "codel.tcl" line 143)<br>
<br>
</div>
How am I supposed to build ns2.35 with the CoDel. And where do the codel.h and codel.cc files come in? I would really appreciate a more detailed response.<br>

<div>In the CoDel.tcl from Dave's git repo, the line your code is choking on is 210 not 143, did you modify CoDel.tcl?</div>
<div><br>
</div>
<div>Also, did you rebuild ns after downloading the CoDel updates? It sounds like ns doesn't know about the queue type CoDel but it is in the
<a href="http://makefile.in/" target="_blank">makefile.in</a> so it should if you did </div>
<div><br>
</div>
<div>cd /ns2/</div>
<div>./configure; make;</div>

<div>Dear Members<br>
<br>
</div>
First of all thank you for the amazing idea that CoDel is :)<br>
<br>
I have downloaded CoDel from <a href="https://github.com/dtaht/ns2" target="_blank">
https://github.com/dtaht/ns2</a> <br>
</div>
In fact I downloaded everything as a zip so that if CoDel needs some other files in the directory I wouldn't miss them out.<br>
<br>
</div>
However, I have been trying to run ns codel.tcl on the my shell. My linux kernel version is 3.6. It gives the following error<br>
<div><br>
ftps 1 webrate 0 cbrs 0 bw 3000000.0 filesize 10000000 reverse 0<br>
accessdly 20 bneckdly 10 realrtt 100 bneckbw 3000000.0<br>
invalid command name "Queue/CoDel"<br>
while executing<br>
"Queue/CoDel set target_ $target"<br>
(file "codel.tcl" line 143)<br>
<br>
</div>
A little help will be highly appreciated.<br clear="all">
