The transition from sequential communications systems such as railroads and
telephony systems to adaptive communications systems such as the Internet
is a paradigm shift. This paradigm shift can also be identified by an emerg
ing new class of technical standards. Technical standards throughout record
ed history are a means to enable communications, inherent in all complex sy
stems, and basic to communications engineering. The fundamental nature of s
tandards is explored using a four-strata taxonomy of standards which relate
s technical standards, communications systems, and value systems to the maj
or periods of recorded history. The emerging fourth stratum of standards, o
ffering new adaptability for communications systems, is described in some t
echnical detail.
