Term:
advanced peer-to-peer networking (APPN)
Definition:
An extension to SNA featuring (a) greater distributed
network control that avoids critical hierarchical
dependencies, thereby isolating the effects of single
points of failure; (b) dynamic exchange of network topology
information to foster ease of connection and
reconfiguration, adaptive route selection, and simplified
network definition; (c) automated resource registration and
directory lookup. APPN extends the LU 6.2 peer orientation
for end-user services to network control; APPC also uses LU
6.2 protocols on its own control point sessions that
provide the network control.
