Advance Program-to-Program Communications
IBM's Advanced Program-to-Program Communications.
Peer-to-peer networking services in an IBM SNA network.
IBM's peer-to-peer protocol for a System Network Architecture (SNA) network. The APPC protocol is independent of the computer operating system, programming language, and hardware interface environment. It allows the client and server to communicate over an SNA network without forcing the client to emulate a terminal.
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.
See definition for Advanced Program-to-Program Communication (APPC).
Advanced Program-to-Program Communication - IBM's solution for program-to-program communciation, distributed transcation processing and remote data access across the IBM product line.
Advanced Program-to-Program Communications. A set of IBM protocols, part of its Systems Network Architecture (SNA), that allows executing applications to communicate directly with one another as peers without intervention by a mainframe host.
An IBM protocol analoous to the OSI model's Session layer; it sets up the necessary conditions that enable applications programs to send data to each other through the network. ... more
