(APPC) Primarily for personal computers in an SNA network to communicate with a mainframe host, this implementation of LU 6.2 uses high-level program interaction.
An IBM protocol analogous to the OSI model's session layer; it sets up the necessary conditions that enable application programs to send data to each other through the network.
Part of the SNA protocol that establishes the conditions that enable programs to communicate across the network. This capability, involving LU6.2 and its associated protocols, allows communication between two or more processes in an SNA network without the involvement of a common host system or of terminal emulation.
