APPN Control Point
An APPN control point is a set of functions that manages node resources and supports both physical unit and logical unit functions on a type 2.1 node. An APPN CP directs local node functions (such as activating and deactivating adapters and links), provides directory and topology information, and assists LUs in session initiation and termination.
Adjacent nodes in an APPN network use a pair of parallel

•Registering resources.
•Routing management services data (such as alerts) between the end node and a focal point.
•Routing topology data from each end node to its network node servers. This information can be used by the network node server to compute a route that does not flow through the network node server.
