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.
Backbone part of the network is a core of the network with its high throughput capability and significant bandwidth. It is made for the ability of network to communicate with external networks (like Internet). It is a root of the network tree, that has rest of the network growing from it.arallel backbone. Parallel backbone is a variation of the collapsed backbone, where devices are having more than one connection between them. As Figure 5 shows, there are multiple connections between the high level routers and the network segments.
