[ns] Rui prior NS-2 SIP module questions
Hi, I'm currently making a brief state of the art of SIP-NS-2 modules in order to use NS-2 in a SIP research project for IMS Network Sizing. Rui Prior's implementation which seems not leveraging NIST-SIP NS-2 module looks very interesting. I was able to recompile (./install) the ns-allinone-2.27-sip-v1_11http://www.ncc.up.pt/%7Erprior/ns/ns-allinone-2.27-sip-v1_11.tar.gz patch on ns-allinone-2.30 running on my REL4-U2 system. Need to update 2 file by hands but that works correctly. I have 2 questions for NS-2 SIP users - Is their doc etc ... describing a litle bit more the Rui Prior's SIP module. This implementation looks very interesting but no piece of doc except a basic readme is provided ? That would speedup our ramp-up on this module - Can Rui Prior explain what is, from his opinion, the main diff between the NIST-SIP module and his Module ? Maturity ? Number of functions ? Thanks for your support Cheers
[ns] AODV and 802.11 link layer feedback
Hi, is there anyone familiar with the 802.11 link layer feedback concerning aodv? I'm currently searching for the variable or statement, upon which the link layer decides that a route is broken(I guess it should be similar to a certain number of unsuccessful retransmission...), and for the exact parts of the code where the failure is propagated by the link layer up to the aodv.

[ns] NS tutorial update proposal
Hi all, I noticed that section VII of Marc Greis' tutorial is seriously out of sync with the NS 2.30 sources. First, the ping example is now included in the apps directory of the ns distribution (this is worth mentioning in the tutorial text), Second, some functionality has been added to the apps/ping example (e.g. broadcast) and Third, the location, encapsulation and access methodology for some (former) member variables has been changed (improved imho, but with the drawback of not being backward compatible). Specifically the third aspect requires to update the tutorial. Newbies are likely to be confused by the changes and compiler errors when they write their own protocols based on the ping sample as a template. The tutorial ping uses members which are no longer valid - e.g. off_ip_, which was apparently replaced by hdr_ip::access(); the src_ member which apprently was changed to a struct, yielding the former src_ in src_.addr_, etc.). NS is sufficiently complex for newbies, anyhow. ;) I therefore suggest to reflect these changes of the ping sources back to the tutorial, and, in addition, modify the comment on line 55 of the NS 2.30 apps/ping.h file (and cc-file) requesting that future changes be reflected to section VII the NS Tutorial. (The tutorial/examples directory seems to anyhow no longer exist)... Thanks in advance, best regards --Joachim

[ns] MM1 queue Analysis NAM question
Hi,
I'm new at ns. I want to analyze mm1 queue and confirm E[N].
I got all the output files. But when i run the nam, i saw that there is not any
packet which goes from node 0 to node 1. How can this happen?
I made the link bandwidth small (set link [$ns simplex-link $n1 $n2 1kb 0ms
DropTail]) and i saw that the packet dropped from node 0 before they go to1.
Shouldn't they would drop near node 1. I think the packets are at the buffer of
npde 1. Why couldn't i see the packets which goes from node 0 to 1?
The tcl code is below:
set ns [new Simulator]
set nf [open out1.nam w]
$ns namtrace-all $nf
set tf [open out.tr w]
$ns trace-all $tf
set lambda 30.0
set mu 33.0
set n0 [$ns node]
set n1 [$ns node]
set link [$ns simplex-link $n0 $n1 100kb 0ms DropTail]
$ns queue-limit $n0 $n1 10
set InterArrivalTime [new RandomVariable/Exponential]
$InterArrivalTime set avg_ [expr 1/$lambda]
set pktSize [new RandomVariable/Exponential]
$pktSize set avg_ [expr 100.0/(8*$mu)]
set src [new Agent/UDP]
$ns attach-agent $n0 $src
set qmon [$ns monitor-queue $n0 $n1 [open qm.out w] 0.1]
$link queue-sample-timeout
proc finish {} {
global ns tf nf
$ns flush-trace
close $tf
close $nf
exit 0
}
proc sendpacket {} {
global ns src InterArrivalTime pktSize
set time [$ns now]
$ns at [expr $time + [$InterArrivalTime value]] sendpacket
set bytes [expr round ([$pktSize value])]
$src send $bytes
}
set sink [new Agent/Null]
$ns attach-agent $n1 $sink
$ns connect $src $sink
$ns at 0.0001 sendpacket
$ns at 1000.0 finish
$ns run
Thanks,
DJ

[ns] NS tutorial update proposal
Hi You are, of course, 100% correct - the tutorial is outdated and its very confusing to first time users. One problem is that, in general, NS2 users ask much, but contribute little when they have their questions solved - either by the help of somebody, or by their own. Some examples from my personal experience: http://mailman.isi.edu/pipermail/ns-users/2006-June/056015.html http://mailman.isi.edu/pipermail/ns-users/2006-January/053560.html - Regarding this particular topic, what I suggest is to: - create a page about NS2 tutorials in the NS2 wiki, which could be used to detail the important changes for recent versions of NS2 of this, and possibly other tutorials. http://nsnam.isi.edu/nsnam/index.php/Main_Page - the next step would be to port the Marc Greis's tutorial to the Wiki (at first, a simple 1 page per chapter copy would be sufficient), which would be much easier to maintain afterwards. However, in my opinion, major improvements in problems like this will only be possible if more users take the action to contribute.

[ns] TFRC simulation problem
Hi Everyone! I have a strange TFRC simulation problem. I am using NS-2.29 in Red Hat. I hvae downloaded Sally Floyd's scripts form http://www.icir.org/tfrc/sims1.html. I run the tfrm12.com. Results I got were quite similar to that presented in the paper but there were several TCP connections that got suprisingly little bandwidth (almost zero). It can be observed whatever is the numer of flows. What can cause this problem ?? I haven't changed anything in the NS files.
