6lo Working Group R. Droms
Internet-Draft P. Duffy
Intended status: Informational Cisco

Assignment of an Ethertype for IPv6 with RFC 4944, RFC 6282 Header
Encoding
draft-droms-6lo-ethertype-request-00
Abstract
When carried over layer 2 technologies such as Ethernet, IPv6
datagrams using datagram encoding as defined in RFC 4944 and RFC 6282
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.

1. Introduction
The IETF has defined a format for IPv6 [RFC2460] datagram encoding in
[RFC4944] and [RFC6282] (6loENC). 6loENC as defined in RFC 4944 and
RFC 6282 may be extended and modified by future IETF standards
document. The intended layer 2 technology for IPv6 datagrams using
6loENC 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 6loENC 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 6loENC frames to upper stack layers. As
specified in IEEE 802.15.9, dispatch of 6loENC frames will require
an Ethertype be assigned for 6loENC.
o 6loENC 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 6loENC
to properly interpret IPv6 datagrams that use 6loENC.
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 6loENC.
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 6loENC. It has no incremental implications
for security beyond those in the relevant protocols.
