Assignment of an Ethertype for IPv6 with LoWPAN Encapsulation


When carried over layer 2 technologies such as Ethernet, IPv6 datagrams using LoWPAN encapsulation as defined in RFC 4944 must be identified so the receiver can correctly interpret the encoded IPv6 datagram. This document requests the assignment of an Ethertype for that purpose.

Status of This Memo

This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at http://datatracker.ietf.org/drafts/current/.

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

This Internet-Draft will expire on October 6, 2016.

1. Introduction

The IETF has defined a format for IPv6 [RFC2460] datagram encapsulation [RFC4944] ("LoWPAN encapsulation"). This document regards any IPv6 datagram using the Dispatch octet as defined in section 5.1 of RFC 4944 to be using LoWPAN encapsulation. LoWPAN encapsulation as defined in RFC 4944 has been updated by [RFC6282], and may be extended and modified by future IETF standards document. The intended layer 2 technology for IPv6 datagrams using LoWPAN encapsulation as originally defined is [IEEE.802.15.4_2011], which does not provide for a protocol switch in its layer 2 headers.

There is interest in carrying IPv6 datatgrams over layer 2 technologies that do include a protocol switch field:

2. Request to IEEE for assignment of an Ethertype

When this document is published, the IETF will formally submit a request to IEEE for assignment of an Ethertype for IPv6 datagrams using LoWPAN encapsulation.

3. IANA Considerations

This memo includes no request to IANA.

4. Security Considerations

This document is intended only to request assignment of an Ethertype for IPv6 datagrams using LoWPAN encapsulation. It has no incremental implications for security beyond those in the relevant protocols.
