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.

Hi
Thank you very much for your help. I did everything you wrote me. I also had
to add line
virtual void recv_msg_from_udp_(int nbytes, const char* msg=0){};to app.h.
But when I try to run ns I have an error and I don't know what to do.
ns:[code omitted because of length]: invalid command name
"Application/Traffic/SipUdp" while executing"Application/Traffic/SipUdp set
burst_time_ 0 "I f you have t! ime and you know what I did wrong can
you help me please?
Thanks in advance.

Hi
I have tried to apply this patch, there are indeed several problems that you
can solve easily and contribute a new patch for ns-2.29.
Failed hunks in common/packet.h:
Basically, everything you need in common/packet.h is PT_SIP (hunk #1m it
succeeded) and name_[PT_SIP] = "sip"; in class p_info (hunk #2, it has
failed). Remaining hunks are not necessary, they are just some garbage.
Failed hunks in Makefile.in:
Many hunks in Makefile.in has failed, but some of them are also garbage.
Just add a new line to the list of objects to compile
sip/sip_udp.o apps/udp_sip \
Failed hunks in trace/trace.cc:
It seems that the purpose of those modifications! is just to put more
information about each packet into the trace file. Nice, but test scripts
should run without those changes, unless they analyse the trace at the end
of simulation. Just remove hunks that relate to the trace.cc file
So, you can take the original patch, remove all the hunks that relate to
the common/packet.h, Makefile.in, and trace/trace.cc files, then make
manually changes in the common/packet.h and Makefile.in files as I have
explained above, try to compile and run. If something goes wrong, you can
contact me. Unfortunately, I have no time at the moment to do it :-(
Also, you may be interested in the SIP implementation that is in the
attachement. I have no idea whether it is a completely different
implementation or just an older version of SIP you are trying to install in
NS-2.29.
Good luck !
