Re: [ns] Strange problem with AWK
Hi
We had the same problems on one workstation. There are two workstations with
Fedora Core 4 Linux. Everything is fine on the first workstation, the second
one has this problem. I have tried to solve it by installing different
versions of AWK - same result. I presume it is not AWK but some library,
maybe glibc, which is responsible for converting the floating-point values.
The only difference between these workstations is that they have different
regional settings. Could it be so that AWK uses somehow those settings and
expect different floating-point separator, i.e. 3.2 and 3,2?
Let me know if you solve it.
Sincerely,

Hi,
I am currently running crazy with a very simple AWK skript... but for any
reason awk does not read any floating point variables from my trace file
BEGIN{
}
{
time = $3
printf("Time: %.6g\n", $3)
}
END{
}
-
The problem is, that I the script just prints the first number and ignors
all other digits
e.g. 0.499890716 --> 0
I also tried printing it as a string, that works, but I cannot use it for
any calculation...
Please help!!

Re: [ns] DiffServ and signalling protocol messages
Hi You make take a look at the following IETF RFC 4594 document http://www.ietf.org/rfc/rfc4594.txt. It reserves some DSCP value for the signalling protocols. However, note that the DiffServ implementation in NS-2 does not support DSCP values higher than 40. Thus, you may need this patch http://www.cc.jyu.fi/~sayenko/src/dsred.diff Sincerely, Alexander Sayenko (PhD) Senior Assistant Telecommunication laboratory, MIT department University of Jyvaskyla, Finland > > Hi, > > I have a question regarding DiffServ and signaling > protocol message.

[ns] OTcl and documentation
Hi Does anybody know/use a well-proven solution to generate a documentation from the OTcl code? I tried to find a one, but failed. * Doxygen does not support OTcl, though it supports Python like comments which can simplify adding support for the OTcl. * The OTcl package comes with the otcldoc script, but it generates HTML output only. I would prefer to have a possibility to control which output I would like to use. * There are several scripts that convert the Tcl code into something like C code so that the Doxygen can parse them but it seems that the OTcl is not suppported. Other solutions? It seems that the NS-2 community would benefit from such a tool since the main documentation has not been updated for years, while the NS-2 code changes all the time. It would also eliminate a need to write the same text twice. Personally, I would like to see the OTcl extension for the Doxygen program because the NS-2 has both the C++ and OTcl code. Does anybody know FLEX well enough to extend the Doxygen scanner.l file ? :-) Sincerely, Alexander Sayenko (PhD) Senior Assistant Telecommunication laboratory, MIT department University of Jyvaskyla, Finland
[ns] WFQ v1.2.5
Hi A new version of WFQ for the NS-2 simulator is available. http://www.cc.jyu.fi/~sayenko/src/wfq-1.2.5.tar.gz The new version solves several small compilation problems that you can experience if you use the latest gcc compiler versions. This version has been tested with the following NS-2 versions: v2.27, v.2.28, v2.29 and v2.30.

Re: [ns] Fwd: Help with WFQ-Scheduler for Wireless networks
Hi You can find WFQ implementation at my Web page, here it is http://www.cc.jyu.fi/~sayenko/src/wfq-1.2.4.tar.gz. However, due to a small bug it is not possible to attach it to the wireless interface in NS-2, NS-2 just crashes. I have fixed it but a new version is not released. In any case, applying WFQ to the 802.16 networks is not a good idea since you will introduce unnecessary complexities. Due to the fact that the WiMAX frame is always fixed and the slots are of the fixed duration, it is more efficient to rely upon the RR schedulers. If you are interested I can send you a paper written by our research group with the simulation results from NS-2.

Re: [ns] how to get current date ($ns now) in c++?
Hi
>From C++ use it is better to use:
Scheduler::instance().clock()
You can also call the Otcl code from C++, but the former will call C++
again. So if you use C++, call C++ functions directly. Here is the Otcl
solution
Tcl& tcl = Tcl::instance();
tcl.evalf("[Simulator instance] now");
Then analyse tcl.result()

Dear NS-users
I am modifying an extension of ns (RSVP-TE\ns), and at some point I need to
have an access to the current date (given in tcl by $ns now). I don't know
how to do this. I suppose I could use something like:
Tcl& tcl = Tcl::instance();
tcl.evalf("%d now", my_simulator_instance);
but I don't know how to refer to the simulator instance.
I would be very grateful if you could help me on this topic.

Re: [ns] How can I estimate delay in Diffserv
Hi First, if you want to estimate the delay, you need AWK or perl script to analyse the trace file. Second, there is no such a thing as a class delay. You can estimate mean delay of packets belonging to some class (or the maximum delay), but you still need to analyse the trace file.

Re: [ns] Weight of a queue
Hi
There are two ways:
* You can call the OTcl code from your C++ code. This is a correct way from
the interface point of view. However, if you want to do it quite often, then
it is better to call C++ function directly
* You can call dsREDQueue::setQueueWeights (int queuenum, int weight). I
think no comments are necessary, the interface is quite straightforward (see
dsred.{cc,h}). The only thing you should remember about is the fact that
these functions can be changed easily in the future.

Re: [ns] SIP patch
Hi
This error means that NS-2 does not know anything at all about the
Application/Traffic/SipUdp class. Indeed, I have looked through the code, there
is no line that registers such a class. Buggy patch :-(
However, as I have understood from the implementation, the Agent/UDP/UDPSIP is
responsible for carrying SIP messages, while Application/Traffic/SipUdp is just
some class that generates traffic. Basically, you can attach any traffic type
you need since the main functionaly is implemented in Agent/UDP/UDPSIP.
So, you can take a test script and use, for instance, CBR traffic type instead
of Application/Traffic/SipUdp. Ideally, it would be nice if some of the
developers clarify this problem.

manually changes in the common/packet.h and Makefile.in files as I have

Also, you may be interested in the SIP implementation that is in the

Re: [ns] Implementation of WRED
Re: [ns] Implementation of WREDHi Those policy, edge and core routers are not complicated, especiall if everything you want to test is WRED. Furthermore, you can always create a simple DiffServ network, which has only the edge router. source -- edge -- destination If you do not want to configure all the policies and meters, you can always use the so-called NULL meter.

Re: [ns] Ns-users Digest, Vol 26, Issue 24
Hi There is no difference between the WFQ and CBWFQ from the viewpoint of functioning (see previous posts concerning this topic). The only difference is how the input classifier works and which packets are put in each queue. You can use the following implementation http://www.cc.jyu.fi/~sayenko/src/wfq-1.2.4.tar.gz to use the both approaches.

Re: [ns] Difference between red.cc and queue.cc
Hi queue.h declares a common class for all underlying queueing mechanisms, while red.h, cbq.h and so on are particular implementations. Just take a look at the class definitions. I have to mention that I do not like an approach taken in NS-2 since it makes many people, and especially beginners, believe that RED is a queueing mechanism. Strictly saying, RED is the active queue management mechanism while algorithms, such as CBQ and WFQ, are scheduling mechanisms. However, NS-2 treats them similarly and that's why it is not possible to use RED and, say, WFQ simultaneously (except the DiffServ framework, of course).
