            TLV Naming in the Mobile Ad Hoc Network (MANET)
                   Generalized Packet/Message Format

Abstract

   This document reorganizes the naming of already-allocated TLV (type-
   length-value) types and type extensions in the "Mobile Ad hoc NETwork
   (MANET) Parameters" registries defined by RFC 5444 to use names
   appropriately.  It has no consequences in terms of any protocol
   implementation.

   This document also updates the Expert Review guidelines in RFC 5444,
   so as to establish a policy for consistent naming of future TLV type
   and type extension allocations.  It makes no other changes to
   RFC 5444.

1.  Introduction

   This document reorganizes and rationalizes the naming of TLVs (type-
   length-value structures) defined by [RFC5444] and recorded by IANA in
   the following subregistries of the "Mobile Ad hoc NETwork (MANET)
   Parameters" registry: "Packet TLV Types", "Message TLV Types", and
   "Address Block TLV Types".

   This document reorganizes the naming of already-allocated Packet,
   Message, and Address Block TLV types, and their corresponding type
   extensions.  It also updates the corresponding IANA registries.

   TLVs have a type (one octet) and a type extension (one octet) that
   together form a full type (of two octets).  A TLV may omit the type
   extension when it is zero.  However, that applies only to its
   representation; it still has a type extension of zero.  A TLV type
   defines an IANA registry of type extensions for that type.

   There have been two forms of TLV allocation.

   The first, but less common, form of allocation has been that
   allocation of the TLV type has defined (but not necessarily
   allocated) all the type extensions for that TLV type.  This applies,
   for example, to the Address Block TLV LINK_METRIC specified in
   [RFC7181].  The LINK_METRIC type extensions are all available for
   allocation for different definitions of link metric.  It is
