Hi Ashley,<br>
<br>
One easy solution is to use a SIP proxy (opensips/kamailio/...) in
front of FS boxes to load balance the charge between boxes.<br>
<br>
FS already has mechanisms to limit number of calls per boxes ( in
switch.conf.xml: max-sessions and sessions-per-second ), <br>
that you can couple to load_balancing modules of the sip proxies.<br>
<br>
Of course you'll have to test to know how many session one box can
handle, has it depends a lot on your usage of FS.<br>
<br>
Don' hesitate to join us on IRC if you want to discuss it ;)<br>
<br>
Regards,<br>
<br>

<br>
I can't find much info on setting up a redundant or heavy load
FreeSwitch implementation. Are there any <br>
links apart from: <a moz-do-not-send="true"

?<br>
<br>
I imagine the entry level solution is to have two FS boxes configured
identitcally, with <br>
redundant SBC software (recommendations?) in front, passing the calls
to the primary FS box,<br>
or the backup FS box if the primary is not responding. Is that the
easiest solution?<br>
<br>
What about a situation of having a level of concurrent calls beyond
what one FS box can handle? I realise<br>
that would be a very large number of concurrent calls, but we would
need a good plan on how to scale the <br>
systems.<br>
<br>
Are there recommendations for load balancing solutions? Either soft or
hardware?<br>
<br>
My guess would be having 3 + 1 spare FS servers would work, where calls
are distributed accross 3 FS boxes<br>
by a load balancer with one spare in event of failure.<br>
<br>
Also how would a FS box at max capacity behave? Does FS monitor
available resources and reject the <br>
excess calls that it can't handle? Or would the load balancer have to
be configured with the maximum number<br>
of calls per box?<br>
<br>
Would love to hear some experiences of deploying FS with failover &
high load.<br>
<br>
<br>
Thanks<br>
Ash<br>
