Hello,
I still might not 100% understand your scenario.
If, on the other hand, we recompute (reshuffle) the list ignoring the inactive servers, the traffic would be properly evenly distributed.
This is what I’m looking for.
But does dispatcher e.g. with a hash based distribution or round-robin does not fulfil this requirement already?
Cheers,
Henning

Difference is if you are distributing based off the username hash and a server goes down, it is simply set as “inactive”, but all calls that were going to that serve will now go to the next in the list, so all
those calls will land on the next server basically doubling the traffic.
If, on the other hand, we recompute (reshuffle) the list ignoring the inactive servers, the traffic would be properly evenly distributed. This is what I’m looking for.
Thanks!

With either module (Dispatcher or Carrierroute) , what would be the functional difference between ‘reloading’ and ‘recalculating’?
Both modules can be controlled via RPC:
Dispatcher can be set to send OPTIONS messages to the hosts in it’s tables to monitor endpoint status and dynamically bring the record in and out of service. Additionally any target’s state can be changed administratively to disabled. Finally, if you update your datasource, dispatcher can be reloaded.
Carrierroute doesn’t have any keepalive options, but supports adding and removing hosts, activating and deactivating hosts, and replacing hosts. Additionally, if carrierroute’s data is updated (i.e. if reading from database) it can be completely reloaded.

Hey Henning, thanks for replying. Quick question: Adding (or removing) in memory recalculates without reloading?

Hello,
this is possible with carrierroute by RPC command: https://kamailio.org/docs/modules/5.5.x/modules/carrierroute.html#carrierroute.rpc.replace_host
With dispatcher you could of course just adding one host two times by some script and reload the module, as a simple idea.

Subject: [SR-Users] recompute distribution list
Hello guys,
Is it possible to have dispatcher recompute the distribution list? i.e. one server goes down, all traffic for that server goes to the next one, doubling traffic on that one. Is there a way of, when a host becomes unreachable, recompute the whole list?
