Network Control Program
The
Network Control Program (sometimes the acronym
NCP is mistakenly expanded to
Network Control Protocol, but this term is not found in the contemporary documentation) is the original
protocol suite of the
ARPANET.
In NCP, the Physical layer, the Data link layer, and the Network layer are all specified by the Host/Imp Protocol. The Transport layer is the Host-to-Host Protocol, together with the Initial Connection Protocol. Layers above that are all joined in with the application (e.g. FTP, SMTP, etc).
