Alia,

Thanks, this is very well reasoned and I find your conclusions compelling.

Yours Irrespectively,

John

Hi Lou and Pavan,

<hat="individual-contributor">
I regret that I won't be able to attend, since this is against the IESG telechat.
Therefore, as an individual contributor on this draft, I am expressing my personal
opinion on the list now.

Frankly, I do not see sufficient interest in the working group or on the mailing list
for this draft to progress.  The draft was an effort to merge two different mechanisms
to solve, via RSVP-TE mechanisms, a problem that is already handled outside of the
protocol in different ways today.  The draft has moved towards expecting traffic into
the LSP to come from an intelligent source, such as a CE; that's fine but that's exactly
the case currently handled outside the protocol.

Despite multiple appeals to the WG mailing list and presentations to try and resolve the
technical conflicts between the two mechanisms, there simply hasn't been interested discussion and even many of the contributors have not engaged.  Efforts to discuss the
technical concerns or options have not led to conclusions. I do not  think the current draft
sufficiently describes the needed behavior for interoperability.  The new draft reflects
an effort to force a result by assertion.

At some point, when there is a clear lack of interest and consensus in the WG, we have
to be willing to say no and stop working on the draft.  It's always hard to suggest this
for something one has worked on, but, in this case, where I still have seen no customer demand and no interest from the WG, I think that is the best option.

After two years, I don't see how we can expect improvement or interest to materialize.

It is, obviously, your call - but since I am listed as a contributor and did pour a considerable amount of effort into trying to fix the draft and methods, I wanted to clearly express my perspective.

Regards,
Alia
