Recently, there have been some questions as to whether the Digital Network
Architecture (DNA) Protocols implemented in Digitals DECnet computer
networking products are in the public domain.  The answer is YES!

It has been our policy to publish the DNA architecture specifications at
the time the first implementations of DECnet products implementing these
specifications are first sold.  We have followed this policy since the
Phase II DECnet products shipped in 1978.  

The current version  of Digital Network Architecture implemented in
DECnet products is called Phase IV, and supports computer networks of
thousands of systems (our internal network currently has over 10,000
registered systems) interconnected by Ethernet local area networks,
dedicated point to point lines and X.25 based data networks.  The protocol
specifications are available on order.


The DECnet General Description [1] provides a semi-technical overview of
the architecture.  This document contains order information for the
complete set of protocol specifications.  This document should be read
first by anyone contemplating implementation of the architecture.

        Order NO. AA-N149A-TC, Digital Equipment Corporation,
