RE: Authorization for AAA and RADIUS work items

["Roy, Radhika R, ALABS" <[e-mail]>]

Hi, Bernard:

I agree that AAA/RADIUS/DIAMETER server MUST not signal QoS.

It is also clear that authentication is also NOT directly related to
QoS.

However, you have agreed that "accounting" has implications on QoS.

I also believe that "authorization" may/will also have implications QoS
as John also mentioned.

So, we have bounded the problems how far we should go for
standardization of QoS attributes for the AAA/RADIUS/DIAMETER server.

So, is it possible to provide clear guidance what we should do in
addressing the QoS attributes?

Subject: Authorization for AAA and RADIUS work items


In order to make sure that AAA-related WGs stay in sync with other WGs
and
SDOs, there is a requirement that AAA-related work items be authorized
by
a requirements document.

Here are some of the AAA requirements documents that have been approved
for publication as RFCs:

draft-ietf-sipping-aaa-req-04.txt
RFC 3141
RFC 2989
RFC 2977
RFC 2881
RFC 2477

Nowhere in these documents is there any mention of AAA requirements for
signaled QoS.

In the NSIS requirements document (draft-ietf-nsis-req-09.txt) there is
a
requirement 5.9.4 that mentions AAA:

"The NSIS SHOULD be developed with respect to be able to collect
usage records from one or more network elements. "

However this seems to only relate to accounting, not authentication and
authorized of signaled QoS.

It would therefore appear to me that use of AAA for signaled QoS has not
been authorized by a requirements document, and therefore cannot become
a
RADEXT (or even AAA) WG work item.
