Thanks Joey! You are awesome man.

Since I did not know what to copy and what not to, I followed everything here

http://pollere.net/CoDel.html

I ran codel after PATCHING it into the ns2 simulator. Then I ran the following command

./ns codel.tcl 4 5 0 100Mb -1 5

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?

The all-in-one install creates may sub-directories for tcl,tk, otcl, tctcl, and most importantly ns-2.35.  

the contents of the  git /ns directory can replace the contents of the ns-2.35 directory. 

after copying the contents cd into the directory and do a 

./configure; make;

then try the command

ns codel.tcl

OK for now,

Dear Joey

I have followed the instructions to build ns2. Let me give you a stepwise description of what I have done.

I have downloaded and installed ns2 from the following source
http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download

After that I downloaded the whole master repository as a zip and unzipped it
 https://github.com/dtaht/ns2

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
ns codel.tcl

after going to ns2-master directory without success. I keep getting the error:

ftps 1 webrate 0 cbrs 0 bw 3000000.0 filesize 10000000 reverse 0
accessdly 20 bneckdly 10 realrtt 100 bneckbw 3000000.0
invalid command name "Queue/CoDel"
    while executing
"Queue/CoDel set target_ $target"
    (file "codel.tcl" line 143)

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.

Safa,

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?

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 makefile.in so it should if you did 

cd /ns2/

./configure; make;

after downloading and unpacking the zip.

Dear Members

First of all thank you for the amazing idea that CoDel is :)

I have downloaded CoDel from https://github.com/dtaht/ns2

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.

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

ftps 1 webrate 0 cbrs 0 bw 3000000.0 filesize 10000000 reverse 0
accessdly 20 bneckdly 10 realrtt 100 bneckbw 3000000.0
invalid command name "Queue/CoDel"
    while executing
"Queue/CoDel set target_ $target"
    (file "codel.tcl" line 143)

A little help will be highly appreciated.
