Advanced Communication Function/Network Control Program definition networking
(ACF/NCP, usually called just "NCP") The primary SNA
network control program, one of the ACF
products. ACF/NCP resides in the communications controller and interfaces with ACF/VTAM in the host processor to control network communications.
NCP can also communicate with multiple hosts
using local channel or remote links (PU
type 5 or PU type 4) thus enabling cross domain
application communication. In a multiple mainframe
SNA environment, any terminal or application can access any other application on any host using cross domain logon.
