Eduardo,
the flag simply introduces a random delay to each packet
(i.
e. the CBR sources does not send 1 pkt ever T seconds,
but every
T+random(-T/2,T/2). I am not sure about the random
interval, but this
is the way it works, and it is useful to avoid
that the two sources
transmit at the same
Hi all,
For some reason when I call trace() from linkcache.cc it does not get
logged in the trace file. I don't have this problem from say routecache.cc.
verbose_debug is set to true, and RTR and AGT trace in the Tcl file are
both switched on.
Can anyone tell me what I am doing wrong?
Hi,
Its not difficult to code such a Ping Agent which would send packets
without getting connected. Actually when u call connect for agents, the
address gets associated (daddr, dport) so u dont need to set these values
when u create a new packet. When agents are connected, what u do is call
Hello all,
I am a BEGGINER using NS, but I haven't been able to run it yet...
I have taken a look at the troubleshooting and help page, but none of the
answers there have helped me so far.
After positioning myself in the directory where NS is installed

In reality, sure. What's happening with the simulation though, is that
the packets are being sent at the same time. Even though you start the
flows sending at t=0 and t=10, when they're both sending, they're
sending at the exact same instant. Since internally, everything is
handled in a
This is an EXCELENT description of what happens in a non-randomized
simulation, and from my experience, I fully agree on that.
It is exactly this kind of material that would be very useful for the NS2
Wiki, to store this information permanently!
As such, somebody on this list please contribute
Hi, I'm really a NS beginner.
I installed NS-allinone-2.29 by Cygwin on WindowsXP and then I downloaded
example1.tcl from Marc Grei's tutorial pages but I have problem processing
it.
This is the error when I launch ns example1a.tcl:
ns: finish: couldn't execute nam: permission denied
