Hello,

it is a matter of the used dispatching algorithm. For a call, first gateway based on algorithm is selected and the rest, starting with the next, are added in a list of avps to be used for failover purposes.

So if you do round robin and one gw is down, if you don't mark it as inactive, 2 calls are going to the next one after the one that is done and 1 call to the third gw, and so on.

Cheers, Daniel

Hi!

Imagine a dispatcher list with 3 entries. I wonder what happens if one of the targets fail. Is the traffic moved evenly to the remaining 2 nodes or is the whole traffic of the broken node moved to one of the nodes?

I took a quick look at the code and it seems that the whole traffic is moved to the next node in the list (i=i+1):

   while (ds_skip_dst(idx->dlist[i].**flags))
   {
           if(ds_use_default!=0 && idx->nr!=1)
                   i = (i+1)%(idx->nr-1);
           else
                   i = (i+1)%idx->nr;

Is my assumption correct?

Thanks Klaus
