Please edit your post to proper spelling : Text speak is not appreciated.

Have you tried using Google ?
I.e. Google .. ns2 vbr .. : 83,000 hits.
Some of the first hits are :
http://ns2homeworkforbeginner.blogsp...1_archive.html
http://code.google.com/p/txsys/sourc...ns2/vbr/?r=222

# 3 .

vbr_traffic.cc : The third link in post #2.
vbr_traffic.cc requires no vbr_traffic.h : Lines 19 - 23 ..
#include <stdlib.h>
#include "random.h"
#include "trafgen.h"
#include "ranvar.h"

# 5 .

When 'vbr_traffic.o' is added to the "Makefile.in" : ./configure && make.
Added 'vbr_traffic.o' to the Makefile : 'make' will do.

A correct line in the Makefile and Makefile.in would be like :
<TAB>vbr_traffic.o \
http://www.linuxquestions.org/questi...4-a-868010/#15
Or like this :
<TAB>tools/vbr_traffic.o\

Quote:
command commence before 1st step
Happens when you type : <TAB>vbr_traffic.o \ <space>
Or : <TAB>vbr_traffic.o\ <space>

.... So you will have to delete the invisible <space> .
I.e. one or more <spaces> will make the "Makefile" fail.

#8 : I don't even know what ABR is. Some ABR here ..
http://en.wikipedia.org/wiki/Traffic_contract

And Google .. ns2 ABR traffic .. : Shows a few relevant hits ?
http://dl.acm.org/citation.cfm?id=847947
""ABR Traffic Congestion Control in ATM Networks with Pole Placement .....
In this paper, we use network simulator ns2 to evaluate the performance of a ...""

.. So I guess you are quite on your own if you want to use abr in ns2.

Also : Google .. ns3 ABR traffic .. : No usable hits.
