This staged migration works equally well in the enterprise backbone. The IP Switch eliminates server bottlenecks by connecting directly to ATM servers. The existing backbone G R A N D functions as a redundant path. Once you WINNER l complete the transition, the IP Switch will ‘°T?.i'ii;:§i°"‘ be the only backbone you’ll need for all your network traffic. oslgggw Ofcourse, the IP Switch supports all §g_,__i current and future IP protocols and applica- Us um tions, including RSVP, QoS (Qualityof Service) and IGMP multicast in hardware. Which means you can avoid the delays and complexity of LANE (LAN Emulation) and MPOA (Multi-Protocol Over ATM Dynamically shifts between store-and-forward routing and cut-through switching. Thanks to an intelligent classication scheme, the IP Switch knows when to switch and when to route based on the type of IP traffic. Longer lasting flows, such as FTP, NPS and HTTP data, and audio/video applications, are optimized by cut-through switching in the ATM hardware. Once a ow is characterized, the ports are mapped in hardware, bypassing the routing software and its processing overhead. Short-lived traffic, including DNS and SNMP queries and mail transfer, is processed through store-and-forward routing. In most networks, 90 percent or more of IP data traffic can qualify for high-speed cut-through switching. Non-IP traffic can also flow through such common practices as tunneling and encapsulation.

|T’S PURE IP. There’s nothing new to leam. No complex ATM protocols. No obscure commands. No new software. In fact, from a management per- spective, the IP Switch is a standard IP node. So you can use your existing management tools and techniques. Or just point-and-click with our intuitive Network Voyager software. As easy as surfing the Web. Network Voyager’s Web-based management software gives you point-and-click access to every port and device on the IP Switch network. That’s because each IP Switch and IP Switch Gateway incorporates a Web server. You can configure, operate, monitor and troubleshoot any part ofthe network with a simple mouse click. IP Switches integrate naturally into the network view of any SNMP- compatible platform.
