Subject: [6lowpan] Fwd: New Version Notification for
 draft-ietf-6lowpan-nd-19.txt
Precedence: list

We have posted a new version of 6LoWPAN-ND, which the authors feel =
closes the editorial and technical issues related to the very thorough =
IESG review. We might still do some minor editing before Vancouver, =
which could result in another revision.

   Changes from -18 to -19:

      o Editorial improvements as a result of IESG comments (#135,
      #142).

      o Extended ABRO with longer version number and valid lifetime,
      while maintaining backward compatibility (#141).

      o Renamed optional features and described them as substitutable
      (#138).

One note to implementors that there was a technical change in this =
document that all existing implementors should be aware of. To solve a =
potential problem with ABRO version number locking, the Authoritative =
Border Router Option was extended with a 32-bit Version number and a new =
Valid Lifetime field. Although this was done in such a way so as to =
maintain backward compatibility, implementations should be updated to =
the final version of this document when possible.=20

> Abstract:
>   The IETF 6LoWPAN work defines IPv6 over Low-power Wireless Personal
>   Area Networks such as IEEE 802.15.4.  This and other similar link
>   technologies have limited or no usage of multicast signaling due to
>   energy conservation.  In addition, the wireless network may not
>   strictly follow the traditional concept of IP subnets and IP links.
>   IPv6 Neighbor Discovery was not designed for non-transitive wireless
>   links, as its reliance on the traditional IPv6 link concept and its
>   heavy use of multicast make it inefficient and sometimes impractical
>   in a low-power and lossy network.  This document describes simple
>   optimizations to IPv6 Neighbor Discovery, its addressing mechanisms
>   and duplicate address detection for Low-power Wireless Personal Area
>   Networks and similar networks.  The document thus updates [RFC4944]
>   to specify the use of the optimizations defined here.
