There are two keys to a good structured wiring system. This eliminates unnecessary internetwork traffic that can slow down the performance of the whole network. Instead of running backbone media throughout the walls, ceilings, and floors of the building, each network segment is attached to a single hub or stack of hubs that connect all the segments and subnetworks to form the enterprise internetwork. The collapsed backbone design was a logical outgrowth of the centralized backbone network design. After all, if all the servers are in a central location for management purposes, the next step is to connect them to a single hub, replacing the backbone cable with the backplane of the hub.
Most hubs offer optional integrated diagnostic and management tools.
A collapsed backbone design provides better management because it offers a single point of network monitoring and control, which also makes troubleshooting easier. It improves security because all servers are moved to a central management area. Most important of all, a collapsed backbone design makes it easy to implement a high-speed network. You can configure backbones physically to accommodate your segmenting scheme. For example, local area network segments on each floor of an office building are connected to a backbone that runs through the conduit from one floor to the next.
