Logical Unit 6.2. IN SNA, an LU that provides peer-to-peer communication between programs in a distributed computing environment. APPC runs on LU 6.2 devices. See also APPC.
An SNA LU type that defines the communication that can take place between two application programs on separate processors. LU 6.2 includes specifications for programmatic interfaces, document interchange, and data distribution.
Another name for APPC (IBM's peer-to-peer networking services provided by SNA networks).
SNA protocol that establishes a session between two programs. Before LU 6.2 processing was done only in the mainframe. LU 6.2 allows processing to take place at both ends of the communications, necessary for today's distributed computing and client/server environment. (See APPC).
An LU-LU session protocol as defined by SNA to support distributed processing; also known as advanced program-to-program communications (APPC) protocol.
An IBM Systems Network Architecture (SNA) protocol. LU 6.2 is a device-independent process-to-process protocol; it also supports asynchronous (store-and-forward) networking. It provides the facilities for peer-to-peer communication between programs. See SNA.
An IBM SNA Logical Unit that provides general communications functions, including the communications functions necessary for peer-to-peer networking. Underlying LU 6.2 is a type of node: node type 2.1, which facilitates peer-to-peer networking. Two SNA units which implement rode type 2.1 can set up a full peer-to-peer session without invoking SSCP capabilities in a host processor. This is defined as SNA Low-Entry Networking.
