RE: Progressing MAM

The Requirements draft calls for a consideration of BC model selection
criteria.  I believe that any specification documents, including RDM,
MAM, or MAR, should provide proper and adequate coverage of these
criteria before they can be ready for WG Last Call.
Thanks, Wai Sum

All,

Now that we have closed on the BC Model approach and decided to document
both the Russian Dolls Model and the Maximum Allocation Model in
separate documents, we need an "official" document for MAM
specification.

Although discussed in a number of I-Ds, MAM was only:
    - defined very succinctly in the diff-te-reqts draft
    - discussed in drafts providing some elements of analysis of the
merits/shortcomings of various models.

This is why I put together a diff-te-mam- draft which is the "mirror
draft" of the Russian Dolls draft (diff-te-russian). This draft aims at
giving a short yet exhaustive specification of MAM (including case where
Local Overbooking is used), examples of CAC formulas to make everything
really unambiguous and include a brief highlight of the main properties
of this model using the WG conclusions that were reached on the mailing
list on this very point.
I would not expect any of its content to be controversial.

I would like to get a sense of the list about using this document as the
basis for the WG MAM specification and for accepting this as a WG
document. Thoughts anyone?

The material providing analysis of the various merits/shortcomings of
various models is very useful stuff for the WG, but I would suggest
keeping this information in a document separate from the MAM
specification. Rationale include:
    - MAM definition has been thoroughly discussed/agreed in WG and
could be finalised very quickly, while detailed analysis still requires
more WG time.
    - pros/cons analysis is of informational nature while the MAM
specification has MUST/SHOULD.

Cheers

Francois
