Military supplement to the ISO Transport Protocol

RFC 1007                                                       June 1987


   Conventions for addressing and Transport connection reference
   number usage and recovery of the Transport connection from peer
   deactivation are covered in Section 5.

1.3   Application.

   The use of the Transport Protocol Class 4 and the Protocol for
   Providing the Connectionless-Mode Network Service (IS 8473) is
   mandatory foruse in all DOD packet-switched data networks where
   there is a potential for host-to-host connectivity across network
   or subnetwork boundaries.  The term "network" as used here shall
   include Local Area Networks but not integrated weapons systems.
   The use of the Transport Protocol Class 4 and IS 8473 is
   strongly encouraged, particularly  where a need for equipment
   interchangeability or survivability is perceived. Use of the
   Transport Protocol Class 4 and IS 8473 in weapons systems, where
   such usage does not diminish required performance, is also
   encouraged.

1.4   International Standards Organization Transport Protocol.

   The international standard upon which this supplement is based is
   described in four documents:

       a. IS 8072, the Transport Service Definition, which defines the
          service that Transport provides to a user, described in
          English text;

       b. WG4 N53, the Formal Description of the Transport Service, in
          which the Transport Service is described using a formal
          description language;

       c. IS 8073, the Transport Protocol, in which the protocol is
          specified in English text; and

       d. N123, the formal description of the Transport Protocol, in
          which the specification IS 8073 is written in a formal
          description language.

   The ISO protocol has five classes of service, named Class 0 through
   Class 4.  Only Classes 4 and 2 will apply to this supplement.  The
   formal description language, Estelle, DP 9074, provides for protocol
   descriptions in terms of communicating finite state automata. It
   contains a subset language which corresponds to the international
   standard Pascal.  The Class 4 protocol operation when supported by a
   connectionless network service is described in an addendum to IS
   8073, N3339(rev).
