AFC: Advanced Communication Function
Advanced communication function (ACF), also known as Advanced Communications Function/Network Control Program (ACF/NCP), often referred as NCP, is the primary SNA network control program. ACF/NCP resides in the communications controller and interfaces with the SNA access method in the host processor to control network communications. ACF/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.
