Capitalizing on IBM's longtime industry leadership in SNA, the IBM 2212 offers High-Performance Routing (HPR) in all-SNA networks for end-to-end flow control, dynamic alternate routing, and priority and bandwidth allocation. The IBM 2212 is also designed as a dependent LU requester (DLUR) and RTP node routing traffic from VSE and other small subarea hosts.
For High-Performance Routing of SNA desktop traffic over IP WAN backbones, the IBM 2212 supports IBM's exclusive Enterprise Extender technology. Related Branch Extender technology, also exclusively from IBM, provides scalability for large SNA networks.
