Terminology
- Advanced Program-to-Program Communication (APPC)
- An implementation of the SNA LU 6.2 protocol that allows interconnected systems to communicate and share the processing of programs.
- Advanced Peer-to-Peer Networking® (APPN®)
- An enhancement for Systems Network Architecture (SNA) networks
featuring:
- Dynamic exchange of network topology information that simplifies connections, route selection, network definition, and reconfiguration
- Automated resource registration and directory lookup
- Greater distributed network control that helps to isolate the effects of single points of failure
- Common Programming Interface for Communications (CPI-C)
- Personal Communications provides support for the Common Programming Interface for Communications (CPI-C) 2.0 industry standard interface from X/Open. The CPI-C interface enables greater application portability across different platforms. By using CPI-C 2.0, APPC programming is simplified, resulting in reduced cycle time, and enhanced client/server computing capability. This support provides the capability for distributed parts of an application to converse with one another. The implementation is consistent with the Conversational function described in the IBM® Open Blueprint®.
- Logical Unit Address (LUA)
- System software and interfaces that supply input/output (I/O) service routines to support communications that use LU types 0, 1, 2, and 3 SNA protocols. These protocols support user defined data streams, SNA character streams, and SNA 3270 data streams. LUA services include only those services that support data communications. LUA does not supply any device emulation facilities.
- Node
- An endpoint of a link, or a junction, common to two or more links in a network. Nodes can be linked to host processors, communication controllers, cluster controllers, terminals, or workstations.
- End Node
- Provides directory and routing services for a workstation on
an APPN® network.
If the workstation will not be connecting from an end node to a network node server, you need to define an SNA connection.
