2.  Overview Of Phase IV DNA Protocols

   The Phase IV DNA protocols which act as data link clients are:

      o  DNA Phase IV Routing
         The Phase IV Digital Network Architecture (DNA) Routing
         protocol is a network layer protocol providing services similar
         to that of DoD IP.  It routes messages in Phase IV DECnet
         networks and manages the packet flow.  The complete definition
         of the DNA Phase IV Routing protocol can be found in [2].

      o  DNA System Console
         The Digital Network Architecture (DNA) System Console protocol
         is a maintenance protocol providing low level access to a
         system for the functions of:

          .  Identify processor
          .  Read data link counters
          .  Boot system
          .  Console carrier (a general purpose i/o channel)

         The complete definition of the DNA System Console protocol can
         be found in [3].

      o  Digital Customer Use
         The Digital Customer Use protocol type is a value reserved for
         use by Digital customers.  It allocates a type for private use
         which will not conflict with Digital or other vendor protocols.

      o  DNA Diagnostics
         The Digital Network Architecture (DNA) Diagnostics protocol
         type is reserved to allow diagnostic software communications in
         parallel with other data link clients.

      o  DNA Naming Service (DNS)
         The Digital Network Architecture Naming Service (DNS) provides
         a distributed naming service.  It allows clients to register
         named objects and to bind a set of attributes to the objects in
         a distributed database.

      o  DNA Time Service (DTS)
         The Digital Network Architecture Time Service (DTS) is a
         protocol providing global clock synchronization in a
         distributed environment.

      o  DNA Load/Dump
         The Digital Network Architecture (DNA) Load/Dump protocol is a
         maintenance protocol for copying the contents of processor
