[Kamailio-Users] Load Based Load Balancing - sr-users

20 May 2009

Hello:

I've been going through your lists and your documentation, and I'm unable to find
how you set up load based load balancing.

To further illustrate:

For example, let's say we have the following live calls:1,2,3,4,5,6,7

Round Robin Works Well
----------------------

+-----+
| SER |
+-----+
   |
   |       +--------------+
   |-------| FreeSWITCH 1 |  [Calls 1,3,5,7]
   |       +--------------+
   |
   |       +--------------+
   |-------| FreeSWITCH 2 |  [Calls 2,4,6]
           +--------------+

But let's say some of the calls end significantly quicker than the others, how can I
send calls by their load (current calls, cpu, etc)

For example, let's say we have the following live calls:1,2,3,4,5,6,7 - Let's say
calls 4 and 5 lasted about 30 seconds, while the others lasted about 5 minutes.  How would
I be able to route calls to the box that's least used - in this example,
"FreeSWITCH 2" at any given time had the least number of calls, so calls 4,5,
and 6 were dispatched to it.

   |-------| FreeSWITCH 2 |  [Calls 2,6]
           +--------------+
