(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.
Data communications support that allows programs on an iSeries server to communicate with programs on other systems having compatible communications support. APPC on the iSeries server provides an application programming interface to the SNA LU type 6.2 and node type 2.1 architectures. Part of IBM's System Network Architecture (SNA).
A set of IBM protocols also known as LU 6.2 and Type 2.1 architectures. It functions within SNA's APPN to support peer to-peer communications between workstations attached to SNA LANs and the applications running on those workstations. It was added to SNA as part of the "new" SNA to support peer to-peer networking, unlike the traditional hierarchical SNA approach in which the mainframe acts as host or master and treats the other computer as a terminal or slave.
High level communications protocol from IBM that allows a program to interact with another program. It provides commands for managing a session, sending and receiving data and transaction security and integrity (two-phase commit). APPC has only supported SNA, utilising SNA's LU 6.2 protocol for session establishment and thus APPC and LU 6.2 have been considered synonymous. In time, APPC will support other industry protocols, such as TCP/IP and OSI.
An implementation of the SNA LU6.2 protocol permitting interconnected systems to communicate and share the processing of programs. See Systems Network Architecture Logical Unit 6.2 and Common Programming Interface Communications.
