SNAplus2 Connectivity
SNAplus2 provides the following new connectivity options:
• High Performance Routing (HPR)
HPR is an extension of the APPN architecture. HPR provides the
following functionality:
— Rapid Transport Protocol (RTP) minimizes the processing cycles
and storage requirements when routing network layer packets
through intermediate nodes on a session route.
— Automatic Network Routing (ANR) enables APPN networks to
automatically reroute sessions around path failures.
• HPR over IP (or “Enterprise Extender”)
HPR over IP provides SNA transport over an IP network. In
conjunction with DLUR, both dependent and independent SNA
sessions can be transported across IP links.
