An APPN node which provides a full set of APPN functions, such as routing between sessions, route selection, and directory services. IBM has published the spec of the network node as part of its attempt to turn APPN into a public standard, and by early 1993, the first non-IBM implementations were available.
A node that can define the paths or routes, control route selection, and handle directory services for the APPN function.
Synonym for APPN network node.

An APPN network node can also attach to a subarea network as a peripheral node or to other end nodes.
