| High Performance Routing (HPR) Routing designed to work in conjunction with (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 Routing Service database and tables. HPR nodes also supports such APPN features as connection networks and support for parallel (TGs). In the HPR architecture, both partner nodes must support HPR for 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. ["APPN Architecture and Product Implementations Tutorial", IBM, GG24-3669-92]. (1997-05-08) |
