DECnet was not OSI.

DECnet Phase V (which very few people apparently use) implemented the
OSI protocols after they had already been developed elsewhere.

BTW, early Internet protocols had already existed for a decade before
what we recognise as today's TCP, IP, and UDP were released in the very
early 1980s so they were an incremental development of what already
existed instead of something new.
