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?

With dispatcher you could of course just adding one host two times by some script and reload the module, as a simple idea.

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?

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!

When you use hash over username kamailio on reload creates the distribution lists I.e:

1- server5 2- server3 3- server8

Now, when a call from userB arrives, it will distribute it for instance to item 2, server3. And any other whose hash is about the same goes to the same.

Now, If server3 fails, it is just ignored, but the list is not recalculated, so all of those calls will go to item3 (server8)
