The collapsed backbone
is the right model for client-server applications, but in this example several workgroups are running out of bandwidth.
The frame-based virtual collapsed backbone
provides a practical migration path from the physical collapsed backbone
because it allows users to realize many of the benefits of switched networking without converting to ATM.
The NuSwitch FE-DS12TF is the ideal collapsed backbone
for the small-to-mid-sized campus environment as fiber is needed to connect remote buildings and unshielded twisted pair (UTP) is used to connect the servers.
Bay Networks' Switch Node routing switch is designed to accelerate IP forwarding in LAN and campus networks, and to front-end and offload existing routers in a collapsed backbone
For example, the Centillion 100(TM) and System 5000(TM) Multi-LAN/ATM switches, the first ATM/Ethernet/Token Ring switch platforms, will be supported by future software releases for PNNI; the Switch Node routing switch, the first true L3 switch with IP AutoLearn, can be deployed today to enhance the performance of frame-based collapsed backbone
networks and augmented in the future with Bay's L3 routing switches based on the RSP ASIC; and the BayStack 350T 10/100 auto-sensing switch, the first of its kind priced below $250 per port, can be used side-by-side with Bay's future stackable 10/100 autosensing switches.
Data center or "power work group" standalone managed switches with up to 15 Gigabit ports or a mix of Gigabit and Fast Ethernet options; and -- Wiring closet, collapsed backbone
, departmental switches -- with high or low port densities that can be standalone or stackable, Layer 2 or Layer 3 Fast Ethernet switches with or without Gigabit options.
Bay's Switch Node routing switch will be used primarily to accelerate IP traffic through routers and to front-end existing routers in a collapsed backbone
architecture, offloading the over-taxed router and delivering wire-speed IP and IPX forwarding.
throughout the collapsed backbone
and providing high-speed Internet
The BANGG network has been constructed with 20-SMC 9432TX adapters, 24-SMC3608TAC-EZ Ethernet hubs, SMC5208 dual-speed 10/100 hubs, and 2-SMC6724TX Tiger Switches 10/100 Gigabit Managed Switch in an Ethernet/Fast Ethernet collapsed backbone
Transition is targeting the SwitchMaster to three key applications: high-speed links, collapsed backbone
and remote access.
