Sure. You might want to right my above statement again. It says "does
need", not "does not". ;) Iñaki Baz Castillo wrote:
I don't thinkt that's accurate. For
many load-distribution schemes
it needs to parse SIP to make the right routing decision.
So in conclusion we are speaking about an IP
based load balancer, and
not about a SIP load balancer. Also we are playing with IP level
exotic technics (various hosts sharing the same IP).
So the above scenario would be valid for any UDP protocol, not just SIP.
The load
balancer does need to be aware of SIP. For this to work, it
needs to send all requests for a transaction to the same proxy. If the
proxies are session-aware, it even needs to send all requests for a
dialog to the same proxy.
I think there is some wording confusion here? What you
are
describing is SIP awaraness. (otherwise you can't really send
the same dialog messages to the same proxy)
Best regards,
