[abfab] Trust router (was Re: Fwd: New Version Notification for draft-wierenga-ietf-eduroam-00.txt)

[Josh Howlett <[e-mail]>]

Hi Klaas,

I probably shouldn't be writing this email until I have finished the
update to aaa-saml :-). However I thought it was worth pointing out that
section 3.3. ('Routing table complexity') is a nice description of the
kind of problem that Trust Router (draft-howlett-abfab-trust-router-ps) is
trying to fix.

But now let us imagine that one was also interested in operating "govroam"
in parallel to eduroam, where they may be some overlap between these
communities. Now, in addition to the naming/connectivity incongruence
described in section 3.3, you can also add incongruence of trust
communities.

My contention is that, for the use cases that Abfab is addressing, the
number and overlap of trust communities wanting to consume identity is in
fact rather large. Therefore it will be significantly cheaper to operate a
single infrastructure that can manage these incongruences, rather than
instantiate N distinct infrastructures for N different trust communities.

It should be as cheap and easy to create and manage a trust community of
arbitrary actors as it is to connect a house full of consumer electronics
to a domestic WiFi router.

Josh.
