IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN)
ESC Dispatch Code Points and Guidelines
Abstract
RFC 4944 defines the ESC dispatch type to allow additional dispatch
octets in the 6LoWPAN header. The value of the ESC dispatch type was
updated by RFC 6282; however, its usage was not defined in either RFC
6282 or RFC 4944. This document updates RFC 4944 and RFC 6282 by
defining the ESC extension octet code points and listing registration
entries for known use cases at the time of writing of this document.

RFC 8066 6LoWPAN ESC Dispatch Code Points February 2017
1. Introduction
Section 5.1 of [RFC4944] defines the dispatch header and types. The
ESC type is defined to use additional dispatch octets in the 6LoWPAN
header. RFC 6282 modifies the value of the ESC dispatch type and
that value is recorded in IANA registry [IANA-6LoWPAN]. However, the
octets and usage following the ESC dispatch type are not defined in
either [RFC4944] or [RFC6282]. In recent years with 6LoWPAN
deployments, implementations and standards organizations have started
using the ESC extension octets. This highlights the need for an
updated IANA registration policy.
This document defines the new "ESC Extension Types" registry and the
ESC extension octets for future applications. In addition, this
document records the ITU-T specification for ESC dispatch octet code
points as an existing known usage.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
3. Usage of ESC Dispatch Octets
RFC 4944 [RFC4944] first introduces this "ESC" dispatch header type
for extension of dispatch octets. RFC 6282 [RFC6282] subsequently
