1.  Introduction

   An Application Data Model (ADM) provides a guaranteed interface for
   the management of an application or protocol in accordance with the
   Asynchronous Management Architecture (AMA) defined in
   [I-D.birrane-dtn-ama].  The ADM described in this document complies
   with the ADM Template provided in [I-D.birrane-dtn-adm] as encoded
   using the JSON syntax.

   Licklider Transmission Protocol Agents (LTPAs) are software instances
   that implement functionality required by the Licklider Transmission
   Protocol [RFC5326].  LTP is a convergence layer protocol.  There is
   no flow control or congestion control in LTP.  LTP must run either
   over UDP or directly over a link layer protocol.  Because of this,
   LTP cannot be used in every situation.  This LTP Agent ADM provides
   the set of information necessary to provide retransmission based
   reliability on challenged networks, focusing on the information that
   an agent on a network implementing LTP would need in order to run
   correctly.

1.1.  Technical Notes

   o  This document describes Version 0.0 of the LTP Agent ADM.

   o  The AMM Resource Identifier (ARI) for this ADM is NOT correctly
      set.  A sample ARI is used in this version of the specification
      and MAY change in future versions of this ADM until an ARI
      registry is established.  This notice will be removed at that
      time.

   o  Agent applications MAY choose to ignore the name, description, or
      other annotative information associated with the component

      definitions within this ADM where such items are only used to
      provide human-readable information or are otherwise not necessary
      to manage a device.

1.2.  Scope

   This ADM specifies those components of the Asynchronous Management
   Model (AMM) common to the management of any instance of a LTP Agent.

   Any Manager software implementing this ADM MUST perform the
   responsibilities of an AMA Manager as outlined in
   [I-D.birrane-dtn-adm] as they relate to the objects included in this
   document.

   Any Agent software implementing this ADM MUST perform the
   responsibilities of an AMA Agent as outlined in [I-D.birrane-dtn-adm]
   as they relate to the objects included in this document.

1.3.  Requirements Language

   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 RFC 2119 [RFC2119].

2.  Structure and Design of this ADM

   The LTP Agent ADM's structure is in accordance to
   [I-D.birrane-dtn-adm].  This ADM contains metadata, edd, report
   templates, and controls.  Externally Defined Data (EDD) are values
   that are calculated external to the ADM system.  Controls are
   predefined and sometimes parameterized opcodes that can be run on an
   Agent.  Report Templates are ordered sets of data descriptions that
   show how values will be represented in a corresponding report.  There
   are no variables, table templates, macros, or operators in this ADM
   at this time.  The contents of this ADM are derived from the main
   functions and data that an agent needs to run LTP RFC 5326 [RFC5326].

   The Metadata that is present in this document is common to all ADMs.
   All ADMs have metadata that includes the name, namespace, and version
   of the ADM as well as the name of the organization that is issuing
   that particular ADM.  This is important for identification purposes
   of the ADMs and to ensure version control.  The main idea identified
   in LTP that is present in this ADM is a span of potential LTP data
   interchange between engines(nodes on a network that use LTP).

3.  Naming and Identification

   This section outlines the namespaces used to uniquely identify ADM
   objects in this specification.

3.1.  Namespace and Nicknames

   In accordance with [I-D.birrane-dtn-adm], every ADM is assigned a
   moderated Namespace.  In accordance with [I-D.birrane-dtn-amp], these
   namespaces may be enumerated for compactness.  The namespace and ADM
   identification for these objects is defined as follows.

                    +-----------------+---------------+
                    |    Identifier   |     Value     |
                    +-----------------+---------------+
                    |    Namespace    | DTN/ltp_agent |
                    |                 |               |
                    | ADM Enumeration |       3       |
                    +-----------------+---------------+

                      Table 1: Namespace Information

   Given the above ADM enumeration, in accordance with
   [I-D.birrane-dtn-amp], the following AMP nicknames are defined.
