A collapsed backbone is a type of network structure or configuration that is sometimes used in the creation of local area networks or LANs.The configuration often includes the use of switching or routing hubs as part of the overall design, with a central point of origin providing the feed for all the hubs. collapsed backbone is a type of network structure or configuration that is sometimes used in the creation of local area networks or LANs.
A networking methodology in which the backbone and switching components are combined into a single device.In a traditional network, local area networks (LANs) are multipoint connections connected using a backbone cable.For example, in a building, a fiber-optic backbone might run from floor to floor and connect with a hub in a wiring closet on each floor.he advantages of using a collapsed backbone are that they eliminate the costs of backbone cabling installation, they require fewer devices, their equipment administration is more centralized, and they offer higher available bandwidth for each station.
