High Performance Routing
     
         (HPR) Routing designed to work in conjunction
        with {APPN} {Intermediate Session Routing} (ISR) network
        nodes.  HPR nodes perform many of the same functions as ISR
        nodes.  For example, HPR nodes use the same method of
        calculating routes based on the {Topology} Routing Service
        database and {class of service} tables.  HPR nodes also
        supports such APPN features as connection networks and support
        for parallel {transmission groups} (TGs).  In the HPR
        architecture, both partner nodes must support HPR for {RTP}
        connections to take place between the nodes.  If one node
        supports HPR and the partner node does not, then the link will
        support ISR functionality only.
