Hi everyone, Thanks to an active discussion among the ND authors, and a bunch of helpful reviews (thanks Richard, Anders and Colin), I finally managed to post 6lowpan-nd-08, in its new slim form (think biggest loser). After Hiroshima we reached good WG consensus to split the ND work into the basic mechanism (which is now this document) and a separate Extended LoWPAN draft (to be started), furthermore we agreed to deal with the DAD issue. This document hopefully moves us very close to that goal. This also includes the new RS feature suggested by Anders.
http://www.ietf.org/id/draft-ietf-6lowpan-nd-08.txt As always with major changes (this needed lots of hacking and major editing), there are surely tons of bugs and loose-ends left. Help to find those appreciated. Changes from -07 to -08: o Removed Extended LoWPAN and Whiteboard related sections. o Included reference to the autoconf addressing model. o Added Optimistic Flag to 6AO. o Added guidelines on routers performing DAD. o Removed the NR/NC Advertising Interval. o Added assumption of uniform IID formation and DAD throughout a LoWPAN. The major open issue we have is how to develop the DAD text in Section 5.3 in such a way that it works for most people, yet produces reliable and safe LoWPANs, and is yet acceptable to the IPv6 crowd and especially the IESG ;-) We are trying to find a balance to keep the WG happy, yet having a chance to actually become an RFC.... It would also be nice to reduce the complexity of NR/NC and especially 6AO message processing. Writing the spec, I am at least not totally happy with the amount of explaining needed.... Is there a sleeker way to deal with the addresses?
