Re: [Serusers] Carrier-grade framework for SER

Hi Klaus, If you refer to origination messages, then by doing a UAR (User-Authorization-Request/Answer)for the originating user to the AAA server. This will offer a way to ballance user registrations between serving sers. If you refer to termination messages, by doing a LIR (Location-Information-Request/Answer) for the terminating user to the AAA server. This will find where the destination users are located. UA->interog.ser->serv.ser->inter.ser->serv.ser->UA UAR^ ^LIR | | +----> AAA server <---+ If you refer to forwarding to new networks or entering the home network, you are right, SRV should be used. Sorry, I have not made it clear enough - I was talking about load balancing and stuff JUST inside the home network. So finding an interogating node, when no AAA server for that domain could be contacted, remains the same. But it should be more comfortable, because interogating nodes are fully stateless and should work very fast.
