[ns] a loop or a start and stop methods
Hi,
I want to execute a ping agent continuously during the simulation, regarding
the schedular object in NS, is there any the difference between making a
infinite loop inside the tcl code or define a start and a stop method inside
the ping agent code(which is a c++ program)

[ns] Traffic generation in a proc
Hi every one,
I wrote a tcl proc for the generation of a cbr trafic :
proc generate_cbr_traffic {agent_src size rate start_time end_time} {
global ns puts "In generate cbr: $agent_src $size $rate $start_time
$end_time" set cbr_ [new Application/Traffic/CBR] $cbr_ set type_ CBR $cbr_ set
packetsize_ $size $cbr_ set rate_ $rate $cbr_ attach-agent $agent_src $ns at
$start_time "$cbr_ start" $ns at $end_time "$cbr_ stop"}
I made the connection of the udp agents outside the procedure , when I call the
procedure, in the NAM environment no traffic was generated ,
Thanks for your help

Re: [ns] Traffic generation in a proc
it works without procedure but as I want the code to be in a procedure in order
to call it several times so I don't have to repeat writing it in different
parts of the program

Hi ns user,
Try to wirte the cbr traffic without procedure to show it is correct or not.
Like

# Set loss monitor (to count bytes) at node 3set null1 [new Agent/Null]$ns_
attach-agent $node_(8) $null1

Hi,
I am still wondering about the no generation of a trafic when it is done by a
procedure although the same code made outside works, but when I put it in a
procedure it does not!!! anyone has an idea

Re: [ns] OK
just to your knowledge, no problem arises for the exponnential traffic, the
procedure works perfectly, can a cbr traffic simulated by a an exponential
with 0 for idle time?

[ns] rtmodel-at down seems to do nothing
Hi micah and all, did you resolve the problem, I have the same one; it is about the use of rtmodel-at in a procedure, it does not work in real time details below thanmks for help Nabila micah said: Hello, The Link Failure code from Marc Greis' Tutorial works fine for me. However, when I use almost the exact same code from my app, the code doesn't seem to do anything. There are no corresponding entries in the network trace or nam files, despite the fact that the code executes. I'm calling the code from C++ via: Tcl &tcl = Tcl::instance(); tcl.evalf( "$ns rtmodel-at %f down $n(%d) $n(%d)", Scheduler::instance().clock() + 0.0001, ip1, ip2 ); I know the code is executing, but nothing seems to happen. There are a few posts on the ns2 listserv archive (e.g., "rtmodel-at doesn't work inside a procedure"), but unfortunately these posts don't have replies. Also, I'm not really running rtmodel-at from within a procedure, unless tcl.evalf counts. A few other helpful notes: I'm not using "$ns rtproto DV" because I don't want dynamic routing. I don't call "$ns rtproto" at all. Links are created using "$ns duplex-link". Any help would be gratefully appreciated! _ Read what Santa`s been up to!
