HI Michael, thanks for the reply. By hosts I mean asterisk boxes, that
would make them SSPs Both of them are connected with one signalling link to
one STP (different STP for each host) wich in turn will connect to the
destination STP(s). I'll try to sketch the scenario
-------------
| Asterisk1 |--voice trunks-
| mtp3d |----------------|STP 1|----------|SSP| (destination point code)
------------- /
| (tcp) /
------------ /
|Asterisk2 |--voice trunks /
|mtp3d |----------------|STP 2|--
------------
As for the variant. it is ITU. And weather it would be primary/alternate or
"load balanced" is under discussion with the connected party. However load
bancing is a possibility.
What I would like to achieve is for incomming messages, both mtp3d route
them to the corresponding host (according to cic and ord opc); and for
outgoing messages, each asterisk deceide on which link (or linkset) send
it.
I thought something like these could be achieved, based on this part of the
below(l4isuop.c), However, I don't get how should i configure it.
switch (link->linkset->loadshare) {
case LOADSHARE_NONE:
if (!link->schannel.mask)
slink = link;
break;
case LOADSHARE_LINKSET:
if (linkset->n_slinks)
slink = linkset->slinks[cic % linkset->n_slinks];
break;
case LOADSHARE_COMBINED_LINKSET:
{
int n_slinks = 0;
int six;
for (lsi = 0; lsi < n_linksets; lsi++)
if (linksets[lsi].enabled)
if (&linksets[lsi] == linkset ||
(is_combined_linkset(linkset,
&linksets[lsi])))
n_slinks += linksets[lsi].n_slinks;
if (n_slinks) {
six = cic % n_slinks;
n_slinks = 0;
for (lsi = 0; lsi < n_linksets; lsi++)
if (linksets[lsi].enabled)
if (&linksets[lsi] == linkset ||
(is_combined_linkset(linkset,
&linksets[lsi]))) {
if (six - n_slinks <
linksets[lsi].n_slinks) {
slink = linksets[lsi].slinks[six -
n_slinks];
break;
}
n_slinks += linksets[lsi].n_slinks;
}
}
}
break;
}
