Thanks, this is very much what I was looking for. It appears the ratelimit/piplimit
modules offer some degree of overload control through queue drops and invite rejections
based on a server's local cpu load. Some of the other overload control mechanisms
described in the RFC (e.g. window based control and loss based control) would also be of
interest to me. Not sure if public implementations exist or if they are restricted to
research implementations. Thanks for the pointer to ratelimit nevertheless.

But also, check out this module:

Sure - I'm referring to mechanisms for the server
to advertise to upstream neighbors to reduce request rates. This could include methods
that appear in RFC 6357 (e.g. rate-limits, window-based control, loss-rate enforcement). I
suppose the try-again-after method would be of interest as well.

Can you elaborate as to what you mean by that term, "overload control"?

Folks,
I'm trying to figure out if either Kamailio or OpenSIPs provides the
various overload control algorithms recommended in the IETF or
elsewhere. I haven't found documentation to this effect. Has anyone
looked into this or used such techniques?
Thanks,
Mike
