I agree. The new format is not only cleaner in how it deals with
fragmentation, multiple hops and extensions; it is also easier to
implement.

have
fewer bugs, different implementors are more likely to end up with

that an
implementation should be easily doable even for the very smallest of
devices.

Folks,
Arch Rock have submitted a proposal for a different 6lowpan header
encoding. David and Jonathan put together a set a slides to describe
their idea to simplify the 6lowpan adaptation header. They are
working
on a complete proposal.
I have posted the slides to the wiki at:
http://6lowpan.tzi.org/FrontPage?
action=AttachFile&do=get&target=6lowpan-header-proposal.ppt
You can also get a copy (if you are wiki challenged) at:
http://www.mulligan.com/6lowpan/6lowpan-header-proposal.ppt
Their design seems to follow the ideas of IPv6, reduce the header
size
in almost all cases, allow for extensions, byte align the fields
and as
I've thought about coding it, it looks like less complex parsing.
While a proposal such as this (ideas tend to come on their own
schedule)
at this late stage in our process will be disruptive, the potential
value of simplifying and fixing some of the identified problems in
the
current design is, in my opinion, worth the time and effort and
risk to
our already blown schedule to evaluate and discuss within the group.
Please take a look at the slides. We only a have few days before the
meeting on Wednesday and if possible I would like to hear peoples
thoughts. I have asked Jonathan and David to attend the WG
meeting and
to prepare a more in-depth presentation related to this new design.
