ARDP - Protocol Specification

ARDP protocol version 0

was the only version of ARDP publicly released until 1998.

ARDP protocol version 1

supports extensions to Version 0; the most important such extension is the use of security contexts, which embed security into the transport layer rather than having it at the application layer as is currently the case when using TCP. The first formal release of an implementation of ARDP protocol version 1 was in 1998, as ARDP Release 1.0.
