RE: [Sipping] SIP-AAA Requirements (fwd)

[Henry Sinnreich <[e-mail]>]

As 3GPP, 3GPP2 and 802.11 wireless networks are poised to use both SIP
and Mobile IP, one cannot help notice there seems to be a lot
commonality between:

1-SIP AAA requirements
http://www-nrc.nokia.com/sua/draft-loughney-sip-aaa-req-00.txt

2-3GPP Requirements on SIP
http://ietf.org/internet-drafts/draft-garcia-sipping-3gpp-reqs-03.txt

3-and most of all, Mobile IP AAA Requirements, RFC 2977
ftp://ftp.isi.edu/in-notes/rfc2977.txt

The mobile IP WG http://ietf.org/html.charters/mobileip-charter.html has
actually covered a lot of groundwork, where it may make sense to avoid
duplication, such as for example for AAA Registration Keys
http://ietf.org/internet-drafts/draft-ietf-mobileip-aaa-key-09.txt

Here are some striking analogies:

Mobile IP    SIP
================
MN-----------UA
FA-----------Visited SIP Registrar
AAAL/H-------SIP AAA
AAAB---------Clearinghouse
See the AAAarch web page
http://iridal.phys.uu.nl/~aaaarch/doc10/home.html and also
http://ietf.org/internet-drafts/draft-johnston-sip-osp-token-02.txt

One more item that the Mobile IP WG has successfully solved is the
separation of specific AAA solutions such as RADIUS, DIAMETER or XML web
services from the mobile IP protocol itself. It is not for the SIPPING
WG to pick winners and losers in AAA solutions and promote one or
another, as has been discussed.

We should try to avoid coming up with several different/incompatible
infrastructures, multiple logons and general annoyance from duplication
of work. Or have the IESG step in to make order.

I believe the SIPPING Mobile IP and AAAarch IP folks should talk to each
other during the WG discussions or maybe possibly at a Bar BOF. I have
taken therefore the liberty to copy the Mobile IP and AAAarch lists.

>John will also be leading discussion on this topic at the interim
meeting next week.
The interested Mobile IP and AAAarch people cannot attend at such short
notice.

Comments are solicited on the SIPPING list only.

John will also be leading discussion on this topic at the interim
meeting next week.
