A new Request for Comments is now available in online RFC libraries. RFC 6775 Title: Neighbor Discovery Optimization for IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs) Author: Z. Shelby, Ed., S. Chakrabarti, E. Nordmark, C. Bormann Status: Standards Track Stream: IETF Date: November 2012 Mailbox: zach@sensinode.com, samita.chakrabarti@ericsson.com, nordmark@cisco.com, cabo@tzi.org Pages: 55 Characters: 130616 Updates: RFC4944 I-D Tag: draft-ietf-6lowpan-nd-21.txt URL: http://www.rfc-editor.org/rfc/rfc6775.txt The IETF work in IPv6 over Low-power Wireless Personal Area Network (6LoWPAN) defines 6LoWPANs 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. [STANDARDS-TRACK] This document is a product of the IPv6 over Low power WPAN Working Group of the IETF. This is now a Proposed Standard Protocol. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
