RFC 1762 PPP DNCP March 1995 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 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 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.
