Assignment of an Ethertype for IPv6 with LoWPAN
Low-Power Wireless Personal Area Network (LoWPAN) Encapsulation
draft-ietf-6lo-ethertype-request-01

Abstract

When carried over layer Layer 2 technologies such as Ethernet, IPv6
datagrams using LoWPAN Low-Power Wireless Personal Area Network (LoWPAN)
encapsulation as defined in RFC 4944 must be identified so the
receiver can correctly interpret the encoded IPv6 datagram. This document requests The IETF
officially requested the assignment of an Ethertype for that purpose. purpose
and this document reports that assignment.

1. Introduction

The IETF has defined "LoWPAN encapsulation", a format for IPv6 [RFC2460]
datagram encapsulation [RFC4944] ("LoWPAN encapsulation"). [RFC4944]. This document regards any IPv6
datagram using the Dispatch octet as defined in
section Section 5.1 of RFC
4944 to be as 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. Standards. The intended layer 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 Layer 2 headers.

There is interest in supporting Ethertype

The following list gives some example use cases for the Ethertype-
based protocol dispatch for
LoWPAN encapsulated the LoWPAN-encapsulated IPv6 datagrams: datagram:

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 for upper stack layers. layer protocol dispatch. As
specified in IEEE 802.15.9, dispatch of LoWPAN encapsulation
frames will require that an Ethertype be assigned for LoWPAN
encapsulation.

o LoWPAN encapsulation will likely be needed for WiFi Wi-Fi Alliance's
HaLoW [HALOW] standard (low power (low-power operation in the 900 MHz band) band).

o Other layer Layer 2 technologies such as Ethernet and debugging tools
such as Wireshark require a unique protocol type Protocol Type field for LoWPAN
encapsulation to properly interpret IPv6 datagrams that use LoWPAN
encapsulation.

o Any existing or future Layer 2 technology, incorporating Ethertype
based
Ethertype-based upper layer dispatch, can use the Ethertype
proposed in this document to dispatch LoWPAN encapsulated LoWPAN-encapsulated IPv6
datagrams.

2. Request to IEEE for assignment Assignment of an Ethertype

When this document is published, the by IEEE

The IETF will formally submit submitted a request to IEEE for assignment of an
Ethertype for IPv6 datagrams using LoWPAN encapsulation. IEEE has
responded with the assignment of Ethertype 0xA0ED for this purpose.
The assignment has been recorded by IEEE [IEEE-ETHERTYPES].

3. IANA Considerations

This memo includes no request

The following entry has been added to IANA. the "ETHER TYPES" subregistry
of the "IEEE 802 Numbers" registry [IANA-IEEE802]:

Ethertype (decimal): 41197
Ethertype (hex): A0ED
Exp. Ethernet (decimal): -
Exp. Ethernet (octal): -
Description: LoWPAN encapsulation
References: RFC 7973 (this document)

4. Security Considerations

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