           IANA Registry for 6lowpan ESC Dispatch Code points
                draft-ietf-6lo-dispatch-iana-registry-02

Abstract

   RFC4944 defines ESC dispatch type for additional dispatch bytes in
   the 6lowpan header.  The value of ESC byte has been updated by
   RFC6282.  However, the usage of ESC extension byte has not been
   defined in RFC6282 and RFC4944.  The purpose of this document is to
   define the ESC extension byte code points and to request
   corresponding IANA actions.

1.  Introduction

   [RFC4944] section 5.1 defines the dispatch header and types.  The ESC
   type is defined for using additional dispatch bytes in the 6lowpan
   header.  RFC 6282 modifies the value of the ESC dispatch type and it
   is recorded in IANA registry [6LOWPAN-IANA].  However, the bytes and
   usage following the ESC byte are not defined in either [RFC4944] and
   [RFC6282].  However, in recent years with 6lowpan deployments, the
   implementations and Standards organizations have started using the
   ESC extension bytes and a co-ordination between the respective
   organizations and IETF/IANA are needed.

   The following sections record the ITU-T specification for ESC
   dispatch byte code points as an existing known usage and propose the
   definition of ESC extension bytes for future applications.  The
   document also requests IANA actions for the first extension byte
   following the ESC byte.
