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 RFC 4944 to
specify the use of the optimizations defined here.
