tcl script for VBR traffic

how to write tcl script for VBR traffic

Is this the correct code for generating VBR Traffic

set vbr [new Application/Traffic/VBR]
$vbr set rate_ 448Kb
$vbr set rate_dev_ 0.25
$vbr set rate_time_ 2.0
$vbr set burst_time_ 1.0
$vbr set n_o_changes_ 10
$vbr set time_dev_ 0.5
$vbr set constant_ false
$vbr set maxrate_ 648Kb
$vbr set packetSize_ 210
$vbr set maxpkts_ 268435456
I have got this code from http://ns2blogger.blogspot.in/2014/0...tation-in.html
I am using NS-2.35 Version

← ref. #3.

http://ns2blogger.blogspot.in/2014/0...tation-in.html
.. is incomplete. Seems based on
http://code.google.com/p/txsys/sourc...ate%253Dclosed
→ $ svn checkout http://txsys.googlecode.com/svn/trunk/ txsys-read-only
→ txsys-read-only/ubiquitous/ns2/src/{ .., .., vbr_traffic.cc },

{ cbr-sim.tcl, vbr-expo.tcl, vbr-normal.tcl, vbr.plot, vbr-uniform.tcl }.

I have no idea. Is for you to try out. Then please post again if any issues.

Is VBR Traffic and Exponential traffic same?
what are Makefile.in & vbr_traffic.o?
Where can we get them? How to Include vbr_traffic.o in Makefile.in?

← ref. #3.

Quote:

what are Makefile.in & vbr_traffic.o ?

Makefile.in is used for generating the Makefile.
`vbr_traffic.o´ is an object file.
→ Is the compiled result from vbr_traffic.cc
→ And is linked together with ~400 other objects, into one file : ns.

Please do :
$ svn checkout http://txsys.googlecode.com/svn/trunk/ txsys-read-only
... to get ( also ) ....
txsys-read-only/ubiquitous/ns2/{ Makefile.in, src/vbr_traffic.cc }

How to include vbr_traffic.cc in Makefile.in

← ref. #7.

» include vbr_traffic.cc in Makefile.in « : Read the link in your post #3 :
"" 1. Include vbr_traffic.o in Makefile.in "".
I.e. files.cc are not mentioned in a Makefile*. The objects to be created are.

Makefile.in is a text file. Easy to read. Or use 'grep' :

Code:

$ cd txsys-read-only/ubiquitous/ns2/

$ grep -n vbr_traffic.o Makefile.in 

179:    tools/expoo.o tools/cbr_traffic.o tools/vbr_traffic.o \

The number, '179' is the line number.
Which you can see in your Editor, when opening Makefile.in for reading.
.... So nothing to add ! vbr_traffic.o is already present.

the Makefile in my NS-2.35 has a little difference in code when compared to the Makefile in http://txsys.googlecode.com/svn/trun...s2/Makefile.in. Should I repalce the original with this new one?

← ref. #9.

Quote:

Makefile.in
.
Should I repalce the original

No. Just add the object to the ns-2.35/Makefile.in :
<TAB>tools/expoo.o tools/cbr_traffic.o tools/vbr_traffic.o \
... and make sure that vbr_traffic.cc is in tools/.

And then run ./install in the top directory ns-allinone-2.35/.

what is "Run make depend in ns-allinone-2.35"?How is this done?

← ref. #11.

All commands are done from the script ns-allinone-2.35/install :
That's the command $ ./install

"install" is a text file, see the ns-2.35 section, lines 531-553,
if you are using the 2011 version ns-allinone-2.35.tar.gz .
If it's the updated version, 2014 : Then the lines 578-587.
Conclusion : The way to run 'make' is $ ./install

Besides that, ./configure && make clean && make doesn't work in ns-2.35.
That was for the earlier ns2 versions.
Also : Saved some time when just running 'make'.
Old slow computer could use ~15 minutes for ./install.
Not an issue with a modern computer.

'make depend' is done automatically in the right way with ./install,
which runs 'make' in ns-2.35/.
A manual 'make depend' has never been attempted.
Somebody wrote 'make depend' many years ago.
And all the young students just repeat it in their texts.

Where should I include tools/vbr_traffic.o\?

Ihave run the command ./install
But I am getting some error
Ihave attached the screenshot of the error
Please suggest the solution

← ref. post #13.

Not Makefile, but 204 random lines from the Makefile.in .
The valid Makefile.in, ns-2.35 has 625 lines.
* Code like post #13 must be in CODE tags.
You can see how code tags look like in post #8.
Please edit post #13 to code tags, or delete the most ..
. http://www.linuxquestions.org/questi....php?do=bbcode
. http://www.linuxquestions.org/questi...gs-4175464257/
I.e. it's the ` # ´ button in the 'Advanced Editor'.
Editing : The 'Edit' button → → "Go Advanced".
.. Or you can type [/code] at code end, and [code] at code text start.

← post #14 : You have missing "ns2 prerequisites".
