Hi ns users,
I some doubt about the RED Queue. I run a
simple tcl script ( can be download from
http://nile.wpi.edu/NS/Example/red.tcl) for RED queue
with 2 TCP sources. I observed that the RED queue just

Hi,
I would to create another identical TORA ad hoc routing protocol in Ns-2.
But i would like it to be renamed as MYTORA.
Can i copy all the files in TORA to a new folder call MYTORA and change
tora.c & tora.h to mytora.c & mytora.h , then edit the Makefile and some
files inside ns-2.29/tcl/lib.
Hi,
The red queue still grow beyond the limit_ if i set
to 100 or 25 or any other value on ns-2.28. Please
refer to redns228.ps.
However, it does not happen when I rerun the tcl
script on ns-2.27. Both ns are run on Fedora Core 4.
Tcl script that I use can be on obtain from
ttp://nile.wpi.edu
hai all,
I got an error as Segmentation fault when I run my scripts(fro c++
codes).
I have created a new agent , but when I try to use that agent in my scripts,
it sends 1 packet and after that it reports segmentation fault.. how to get rid
of it. plz help me.
Thanks.
Hi
Since many VoIP codecs send data at the constant rate, you can use normal
UDP/CBR application to simulate VoIP. You have to set appropriate parameters
so that the rate and the packet size correspond to the codec you use.

HI friends,
As we know CBR connection use an option type
packet/sec to be sent. Is that means they are sent at regular interval. i.e. 4
packet/sec means it will send the packet at regular interval of .25 sec.
But i think it is not the real world communication.

The instantaneous RED queue size shouldn't grow beyond the actual RED
queue size, and the average RED queue size shouldn't grow beyond the
maxthresh.
You may want to check your parameters again.

The very fact that you are using CBR taffic means that the packets you are
sending will be at a constant rate (in you case at an interval of .25 secs).
Your second case defines bursty traffic - characteristics of TCP traffic
where packets equal to the congestion window value are sent out at a time

You need to set the queue size by modifying the following two lines.
$ns queue-limit $node_(r1) $node_(r2) 100

A trace file will generally always be like that. A line is put into it
every time a packet moves up or down the stack. If you wish to create a
graph in any reasonable amount of time you must write (or find I
suppose) tools to parse the traces. They are human readable, but don't
be fooled into
