The issue here, of course, is whether a virtual collapsed backbone
is best or if an integrated routing/switching backbone is needed.
In a frame-based virtual collapsed backbone
, workgroup- level frame switches replace (or assist) overtaxed shared-media hubs and ease desktop bottlenecks.
As bandwidth demand increased, the company installed high-performance NETBuilder II1 bridge/routers as the collapsed backbone
The switch can serve as a concentrator for a wiring closet, or in a collapsed backbone
in small office/branch office LANs.
Wiring closet, collapsed backbone
departmental switches -- with high or
2-Gbps backplane capacity and a large buffer size of 32 MB, the StellarSwitch SGX8216 is suitable for demanding applications such as deployment as an enterprise collapsed backbone
For high-performance routing of legacy protocols such as AppleTalk, Vines, DECnet, and SNA, the Accelar routing switch can be connected to servers and clients creating multiple VLANs that are ultimately terminated in the BN router to form a collapsed backbone
Completed this April, Bates' new network is based on a collapsed backbone
comprised of two redundant, CoreBuilder 9000 enterprise switches.
