As soon as messages are pulled from the receive buffer they are suspended and queued.  So it is the minimum processing required to pull them into Kamailio.  The let us say you have three queues.  Priority 1 messages are queued with queue 1, priority 2 in queue 2, priority 3 in queue 3.  Instead of dequeuing the queues in separate processes (as I do) you dequeue them in one process.  You empty queue 1 first, then queue 2, then queue 3.

Won't that do what you want?

@peter,
I don't get it?? Your module mqueue seems to be doing IPC. What I want to do is prioratize messages that come to the server according to their behaviour...
What I want is to have n queue :

                        |                                       Prio n                                                 |

IN would come from the OS (messages which has been identified as SIP messages)
OUT would go to the kamailio processing part. i.e. it would now be actually reach the kamailio core.

Hi,

I have been using a configuration file based system to share certain SIP requests across different queues for handling by different processes.  Such a scheme could be adapted for prioritisation.

I have posted several configuration fragments for this on the list so you should find them if you look in the archives.  My email from 28 March (at around 14:44) is probably the closest to what you are wanting.

Regards,

Peter

Hi Olle,

What I want to do is test a "hypothesis" for congestion control using prioritized scheduling of messages....
But thx for that input regarding the newer message queue module....i'll look into it...

Can you elaborate a bit more? What do you mean with scheduling for SIP messages?

We have a few new modules where you can queue messages for later processing and time their transmission. Check those first.
