Assignment of an Ethertype for IPv6 with LoWPAN Encapsulation
draft-ietf-6lo-ethertype-request-00
Abstract
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

Internet-DraftEthertype for IPv6 with LoWPAN Encapsulation April 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:
o Usage of LoWPAN encapsulation in conjunction with IEEE 802.15.9
Multiplexed Data Service [IEEE802159], which provides the ability
to perform upper layer protocol dispatch for IEEE 802.15.4
networks. Wi-SUN Alliance intends to use the 15.9 Multiplexed
Data Information Element to dispatch LoWPAN encapsulation frames
to upper stack layers. As specified in IEEE 802.15.9, dispatch of
LoWPAN encapsulation frames will require an Ethertype be assigned
for LoWPAN encapsulation.
o LoWPAN encapsulation will likely be needed for WiFi Alliance's
HaLoW [HALOW] standard (low power operation in the 900 MHz band)
o Other layer 2 technologies such as Ethernet and debugging tools
such as Wireshark require a unique protocol type field for LoWPAN
encapsulation to properly interpret IPv6 datagrams that use LoWPAN
encapsulation.
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.
