Hi all,
I cannot be more agree with Lionel's comments here. I support the
consensus taken in PANA WG and the content of the slides.
Best regards.

Hi all,
I second lionel. PANA fulfills DSL Forum requirements and should be
considered as a serious candidate.

The list of requirements is the only material available from the DSL Forum and
we should stay focus on!
Actually I refer to a previous mail that I sent on this topic on the Intarea ML:
(snip)
"Now, one "could" say that the PANA protocol specification is "quite"
stable as a Proposed Standard RFC is available ;) Therefore, the question is
quite simple: why do not simply reconsider the use of PANA in DSL environment?
The proposed alternative, i.e. DHCP-based authentication, that is for the
moment only an individual submission at IETF, will have anyway impacts on the
DHCP client, the DHCP server and DSL network node behaviours if the goal is to
have EAP in DHCP. And the proposed alternative do not explain why the current
possible solution(s) don't fulfil the DSL Forum requirements... And I'm not
sure that there is a direct link between the existing use of the DHCP option 82
in DSL network leads seamlessly to DHCP-EAP...
At least, a pragmatic approach within IETF would be to see how PANA can fulfill DSL forum
security requirements, see if there is some functionality gaps, see if this gap could be
fulfilled with within PANA or with possible add-on solutions and if not, see other
alternatives should be investigated. Only because IETF has already defined "the
Protocol for Carrying Authentication for Network Access (PANA), a network-layer transport
for Extensible Authentication Protocol (EAP) to enable network access authentication
between clients and access networks."
I support the actual ongoing work in the PANA WG to clarify the fact that PANA,
as a candidate protocol, is fulfilling DSL requirements. It is not said that
PANA is the ultimate solution for DSL networks. It is just said that the PANA
protocol should be considered as serious candidate protocol.
And I agree with the current content of the slides.

Objet : Re: [Pana] RE: DSLF Requirement analysis
I have a feeling that the two things are mixed in the
discussion : (i) whether a requirement is satisfied, and (ii)
how complex a solution would be to satisfy the requirement.
I suggest we focus on (i). I have a problem with discussing
(ii) here, because it tends to be based on additional
unwritten requirements such as "number of states" and
"troubleshoot" and I cannot agree on arguments based on
unwritten requirements.
