RE: [manet] RE: [Manet-dt] Re: PacketBB

I know, top-posting is more evil than NAT. But
sometimes you need NAT, and sometimes ...

It's not just specific to DYMO, it's pretty specific
to a 16-bit addressed unexpandable version of DYMO
that would have no possibility of adding e.g. NHDP-
based optimised flooding - which can save you tens
of copies of a message rather than bytes per message.

I cannot see how we can produce a format which has the
flexibility that we need while offering the compression
that Romain is after. I think to cripple packetbb in
saving a few bytes that will still not be acceptable
to Romain is going to please no one.

Please note I'm not saying Romain is wrong, I'm saying
he has a different problem (or rather an extreme set of
weightings of the requirements) and produces a different
solution.

What would be interesting would be a fully specified
set of preconditions on which subset of packetbb is
being addressed, and a fully specified translation
(compression/decompression) process between the two
(or some evolution thereof). If anyone wants to write
one, I'll read it. You might find 6LoWPAN interested.

> What do you think about Romain's proposal?

I don't know; I was just starting to look at Wesley's
proposal and hadn't gotten around to Romain's yet. But
on first glance, it seems to be specific to DYMO; can
it be generalized to other protocols? (I probably won't
have much time to look at this in more details...)
