Thanks, Ken.

The idea is this:

A main document (A) in which we explain the method, the scenarios and the
minimum signaling issues in order to make it work. The idea is that document
(A) would be self-contained. Since we are not defining new protocols (i.e.
already existing compressing, multiplexing and tunneling protocols are to be
used), we understand that this can be done in a single document. It would
include:

1- Protocol stack (it would be the "reference model")
2- a negotiation mechanism to decide the options to use at each layer
3- a mechanism to setup/release a tunnel between a multiplexer and a
de-multiplexer

Of course, another approach could be separating 1 from 2&3. However, we
think this is not necessary since the method is not too complicated.


Document (B) would only contain recommendations of how to better use the
method proposed in document (A), i.e., classification and maximum delays.

So clearly document (B) would totally depend on the reference model of
document (A).


The idea of point 9 is to talk about some other interesting ideas which are
considered as "future work":
- a mechanism for a multiplexer to discover a de-multiplexer
- mechanism to select an optimal multiplexer and a de-multiplexer when there
are more than one muxer/de-muxer for a flow
- dynamically applying TCMTF
- etc.

What do you think?

Thanks again for your feedback. Thinking and explaining things is always a
good exercise!

Jose
