Multiple Queues in Kannel?

Question

Hi i am using kannel in one of my projects and i want to know how to be able to implement multiple queues in the push mode. For the pull mode i checked some posts and found out that kannel does not implement any mecanism of queuing for the outcoming SMS, because the system should resist in the high load scenarios.

I a very new at kannel. i've tried their documentation but so far did not get the main idea for the push mode. Thank in advance.

You can rely on sqlbox to implement multiple queues before tapping on bearerbox for delivering MT traffic.

Install sqlbox and run 2 instances, each one is connected on a different couple of sql tables, let's say:

1. queued_1 and sent_1
2. queued_2 and sent_2

And then you'll have to insert your SMS-MT into queued_1 and queued_2 tables with a roundrobin algorithm so you can load-share the traffic on both sqlboxes.

But dont get it wrong, bearerbox still have its own queue, and it's a one-queue-per-smsc, this is a memory based queue which gets filled whenever the smsc doesnt respond (with submit_sm_resp) or rejects delivery.
