Hi Sam,

ok, although it runs federation routing and topology information, and
forwards eap authentications. It plays a lot of roles :)

I can understand the AAA path in this case, but l think this mixed path
is very complicated. If every realm implements this functionality like a
AAA server it would be more interesting.

This is an important point that may required another important number of
exchanges, in order to build and exchange the federation topology (I'm
thinking here in something like eduroam) and to query that path by the
RP (although I suppose here only 2 messages are needed)

Have you analysed how this process (I count 18 messages for 4 realms
without routing and attribute request exchanges) could affect specific
services like SIP?
 
Thanks a lot for your comments Sam, I think this explanation (completed
with the routing part) should appear in the next version.

Best regards, Gabi.
