See IBM Systems Network Architecture Advanced Peer-to-Peer Networking Architecture Reference for additional information about the PU 2.1 environment.
With PU 2.1 support, the SSCP is replaced by a control point (CP). When the TPF system is operating in APPN mode, there is one CP name for the entire TPF loosely coupled complex. One TPF processor has CP-CP sessions with an adjacent APPN network node (NN) and manages all the resources for the complex.
CP-CP sessions are a pair of LU 6.2 sessions between adjacent CPs. LU 6.2 support must be installed for the TPF system to be able to connect to the network as an APPN node. See TPF/APPC Installation Checklist for information about installing LU 6.2 support on the TPF system.
