Matt,
Thanks for putting this together. It is clearer when
you have diagrams like this. It seems like we ought to reserve bits/octets
if we aren't going to use them in a field. It's kind of odd that the
32-bit proposal header takes up 3 words and the 64 bit proposal header takes up
2 words. The TTLV format should be a different discussion than the bit
alignment. I prefer the TTLV format of the 64 bit alignment proposal, but
either will do.
One thing your diagram doesn't show is that padding in the
32-bit proposal is either 1 to 3 bytes while the padding in the 64 bit proposal
is 1 to 7 bytes to get the alignment. Your examples in the other proposals
clearly show this.
Thanks for clearing this up,
Scott
Hi Folks,
I've put together a diagram that shows the
difference between the 32-bit and 64-bit proposals in graphic detail. For
these types of comparisons, words don't quite express the idea as well as
pictures do.
As the poll showed, the group is about halfway split between
32-bit and 64-bit, and I'm hoping that this diagram will show that the 64-bit
proposal works just as well for 32-bit applications. :)
With
any luck we'll reach a conclusion via e-mail and will be able to have a quick
vote in tomorrow's meeting to pick one of these proposals. I do prefer the
64-bit option as more useful, but would be happy to approve the 32-bit version
if that's the group's favorite.
Let me know if you have any comments or
questions!
Cheers,
-Matt
