Hello,
Indeed, we had some discussions with Ken Rice about interconnecting
OpenSIPS and FreeSwitch. The main idea is to make use of the
Load-Balancer module in OpenSIPS (please note this is not a simple
dispatcher or probabilistic/hashing routing, but actually a LOAD based
routing engine) and have this LB module connected into FreeSwitch to
collect information about real load on FS (currently, LB module in
OpenSIPS counts as load the number of ongoing calls). But as here
suggested, the load on FS can be evaluated based on CPU/memory usage or
any other internal FS parameters which may be relavant.
The interconnection between OS and FS can be either via one of the FS
APIs (having the two software talking directly) or, as Jay suggested,
directly via SIP OPTIONS (when to add the load info in replied can be
determined based on the src IP of the OPTIONS request).

This would be a pretty cool feature and I know that OpenSIPS guys have
discussed such a feature with FreeSWITCH dev. This would be a great
addition for load balancing.

Hello List,
i read too the nice
http://wiki.freeswitch.org/wiki/Enterprise_deployment Enterprise
Deployment Setups.
Personaly i run FS 1.2.x as Session Border Controller where sip
clients could register and internal (3rd party) IVRs could reachs
the clients.
I plan to use DNS SRV on the to scale up the FS Servers and have
fault talerance.
For that i have to diffrent uplinks that i could use for the DNS
SRV Records and AFAIK i could use track-calls=true in sofia profiles
to track the right incoming/outgoing profile.
The only thing i missed is that my 3rd party IVRs used FS as
outbound proxy and therefore only one IP is spezified on the
internal network.
With an virtual IP on the FS side i could solve that but then the
FS servers is IMHO limited to be a active/passiv duo.
Any ideas how to handle that?

So I want to bash out a feature I was thinking of, please can
anyone chime in some ideas on this.
So its easy to have OpenSIP / Kamailio ( dispatcher ) send SIP
Options to FS to see if its responding .. this is great ...
My request would be to have some kind of control over the
response FS Sends back.
What I would love is to respond with idle CPU , current SPS /
Max SPS or channels / Max Channels.
This is only a high level "this would be nice" , so I havnt
totally thought this through but...
we would have to provide an ACL for who to provide this back
to, coz I wouldnt really want any old guy on the internet
sending me options and me respond going ... oh yea bro, Im at
90% ... dont have to try hard to DDOS Me.. :)
but yea... if we could give this back to the load balancers,
then we could easily instruct them to back traffic off to this
gateway.
the next part is , how do you back off the traffic.
one option is to have FS respond differently if any of these
are close to thresholds.
or to provide these values in custom headers, but that would
require changes in dispatcher ( which is ok I Guess )
anyways... I wanted some input on peoples thoughts here..
let me know what you think.
Jay
