| network node A Systems Network Architecture (SNA) intermediate node that provides connectivity, directory services, route selection, intermediate session routing, data transport, and network management services to low-entry networking (LEN) nodes and end nodes (ENs). The NN contains a control point (CP) that manages the resources of both the NN itself and those of the ENs and LEN nodes in its domain. NNs provide intermediate routing services by implementing the Advanced Peer-to-Peer Networking (APPN) PU 2.1 extensions. Compare with EN. See also CP. |
