Internet Engineering Task Force (IETF) S. Chakrabarti Request for Comments: 8066 Updates: 4944, 6282 G. Montenegro Category: Standards Track Microsoft ISSN: 2070-1721 R. Droms J. Woodyatt Google February 2017 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.

Standards Track [Page 2] 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] subsequentlyShow full document text
