             IEEE 802.15.4 Information Element for the IETF

Abstract

   IEEE Std 802.15.4 defines Information Elements (IEs) that can be used
   to extend 802.15.4 in an interoperable manner.  The IEEE 802.15
   Assigned Numbers Authority (ANA) manages the registry of the
   Information Elements.  This document formulates a request for ANA to
   allocate a number from that registry for the IETF and describes how
   the IE is formatted to provide subtypes.

1.  Introduction

   IEEE Std 802.15.4 [IEEE802.15.4] is a standard, referred to by RFC
   4944 [RFC4944] and other documents, that enables very low-cost and
   low-power communications.  The standard defines numerous optional
   Physical Layers (PHYs) operating in many different frequency bands
   with a simple and effective Medium Access Control (MAC).

   IEEE Std 802.15.4 defines Information Elements (IEs) that can be used
   to extend 802.15.4 in an interoperable manner.  An IE provides a
   flexible, extensible, and easily implementable method of
   encapsulating information.  The general format of an IE as defined in
   Section 7.4 of IEEE Std 802.15.4-2015 [IEEE802.15.4] consists of an
   identification (ID) field, a length field, and a content field.
   Multiple IEs may be concatenated, and elements with unknown ID values
   in a list of IEs can be skipped since their length is known.  IEs
   provide a flexible container for information that allows the addition
   of new IE definitions in future versions of the standard in a
   backwards-compatible manner.

   There are two different IE types, Header IE and Payload IE.  A Header
   IE is part of the MAC header; it is never encrypted, but it may be
   authenticated.  Most of the Header IE processing is done by the MAC,
   and IETF protocols should not have any direct effect on that
   processing.  A Payload IE is part of the MAC payload and may be
   encrypted and authenticated.

   IETF protocols will need to insert information in the 802.15.4
   frames; the 802.15.4 standard enables that by including one or more
