Mark, I can publish such a rev. Will split the "timestamps generation" into a separate I-D, and will address in the current draft those points that needed clarification, etc. Thanks, Fernando Mark Allman wrote: > Catching up, I will chime in with three things ... > > - It still seems to me like we have pretty well converged that the > draft's value is in terms of the TIME_WAIT truncation scheme. > > - My own opinion is that the draft can simply say "this scheme works > best with monotonically increasing timestamps" and leave it at > that. > > I.e., it isn't a strict requirement because the fall-back is just > what we have without timestamps and if it were a strict requirement > we'd have to think about flags and such. > > I.e., TCP implementers are smart folks who don't need RFC pages to > define for them how to generate a monotonic sequence of timestamps > and so my view is that doing so is useless detail. > > - I agree with Joe's note below that this discussion has led to an > evolved understanding of the issues and what will be in the draft > and it'd be nice to see either (a) a new draft from Fernando that we > can adopt or at least (b) an outline from the chairs that sketches > a WG document and its major components that can then be filled in by > some editor. > > allman > > > > >> The 03 draft focused on creating an algorithm that prevented guess-based >> attacks. >> >> The discussion, as far as I can tell, has focused on the most peripheral >> part of 03 - the use of TS to cut TIME_WAIT. >> >> IMO, that's a sufficient change that we're no longer considering a mere >> evolution of 03.
