<div class="moz-cite-prefix">Hi, Daniel, about this :<br>
<br>
<pre>A distributor thread (or process) won't help here, if it distributes
traffic to other threads (processes) without waiting for them to finish,
which ends up to be serial processing. The distributor role for UDP
traffic is done by the kernel. For tcp/tls there is a distributor
process for connections.
Cheers,
Daniel
</pre>
I disagree. A distributor thread could do something as simple as
apply a hash to the Call-ID, and use it to select the process to
send the message to, without waiting. the process will recive all
messages for a specific call-leg.<br>
it does not need to wait for an answer nor it needs states, as
"which process is processing which message at any time".<br>
<br>
I think the main problem is that it introduces a bottleneck, and
break the main philosophy of Kamailio's architecture, having only
individual processes.<br>

<p>Hello,</p>
<p>you have to keep in mind that Kamailio is a SIP packet router,
not a telephony engine. If 180 and 200 replies are part of a
call is not something that Kamailio recognize at its core. Its
main goal is to route out as fast as possible what is received,
by executing the configuration file script. Now, a matter of
your configuration file, processing of some SIP messages can
take longer than processing other. And the processing is done in
parallel, a matter of children parameter (and tcp_children,
sctp_children).<br>
</p>
<p>With that in mind, a way to try to cope better with the issue
you face is to set route_locks_size parameter, see:</p>

<p>Probably is what you look for.</p>
<p>But if you want more tight constraints, like when receiving a
180 after a 200ok and not route it out, you have to make the
logic in configuration file by combining modules such as dialog
or htable (as already suggested).</p>

<p class="MsoNormal" style="margin-left:35.4pt">I am
worried about this scenario, because it's a symptom of
what may happen in other cases. For instance, I've seen
that this operator usually sends re-invites immediate
after sending ACK. This may create race conditions
like 3.1.5 of RFC5407<br>

I'd understand that one happens because of packet loss,
as it's in UDP's nature, but in this case it would be
artificially created by Kamailio. if there was no
problem at network level (packet loss, packets following
different path on the network and arriving out of
order), why Kamailio creates it? <br>
<br>
I'd expect that the shared memory is used precisely for
this. If an instance of kamailio receives a 200 OK, it
could check on the shm and say "hey, another instance is
processing a 180 for this call. Let's wait for it to
finish" (*). I know there could still be a problem, the
instance processing the 180 undergoes a context switch
just after it receives the message, but before writing
to shm, but it would greatly reduce the chance.<o:p></o:p></p>

our applications we use a SIP stack that always sends
messages to the application in the same order it
receives them, even though is multi-threaded and
messages from the network are received by different
threads. So, they really syncronize between them. Why
Kamailio instances don't?<br>
<br>
I am evaluating kamailio to use it as a dispatcher to
balance load against our several Application Servers, to
present to the operator just a couple of entrance points
to our platform (they don't want to establish
connections to each one of our servers). This operator
is very difficult to deal with. I am sure they will
complain something like "why are you sending messages
out of order? Fix that". The operator will be able to
see traces and check that messages entered the Kamailio
nodes in order and left out of order. They will not
accept it.<br>
<br>
(*) Not really "wait", as it would introduce a delay in
processing all messages. it should be like putting it on
a queue, continue processing other messages, and go back
to the queue later.<br>

sometimes they are propagated out of order. 200 OK
before 180, like this :<o:p></o:p></p>
<p style="mso-margin-top-alt:5.0pt;margin-right:0cm;margin-bottom:12.0pt;margin-left:70.8pt"><img style="width:6.2187in;height:2.177in" id="_x0000_i1025" src="cid:part12.87A77625.2B5BA5E8@sixbell.com" class="" width="597" height="209" border="0"><o:p></o:p></p>
<p style="margin-left:70.8pt">UAS is 172.30.4.195:5061.
UAC is 172.30.4.195:5080. Kamailio is
192.168.253.4:5070<o:p></o:p></p>
<p style="margin-left:70.8pt">Difference between 180 and
200 is just about 50 microseconds. <o:p></o:p></p>
<p style="margin-left:70.8pt">My guess is that both
messages are received by different instances of
Kamailio, and then because of context switches, even
though the 180 is received before, that process ends
after the processing of 200. However, I had the idea
that in order to avoid these problems the kamailio
processes synchronized with each other using a shared
memory. I tried using stateful proxy and I obtained
the same result.<o:p></o:p></p>
<p style="margin-left:70.8pt">By the way, anyone has any
idea about how Kamailio's share memory is implemented?
It clearly does not use the typical system calls
shmget(), shmat(), because they are not shown by ipcs
command.<o:p></o:p></p>
<p style="margin-left:70.8pt">Before posting here I
googled, but I couldn't find anything related to this.
I can't believe I am the only one who ever had this
problem, so I guess I am doing something wrong...<o:p></o:p></p>
<p style="margin-left:70.8pt">Please, any help. I'm
really stuck on this.<o:p></o:p></p>
<p style="margin-left:70.8pt">Thanks.<o:p></o:p></p>
