IBM has rolled out a new hardware device, dubbed Network Utility, that is capable of translating SNA to TCP/IP and vice versa for up to 40 per cent less than a front-end processor or channel attached router. Network Utility clearly is aimed to compete with Cisco Systems' channel attached routers. Network Utility will come in two models: the TN1 tn3270e Server for data centre users, and the Model TX1 Transport for use in remote branch offices. Both models have two slots that can support token ring, Ethernet, FDDI or ATM LAN connections and Data Link Switching (DLSw), as well as LAN bridging protocols. DLSw lets SNA traffic flow over an IP backbone.
