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.
Definition. Network cabling scheme in which one cable sequentially connects all nodes and forms a closed loop. A data packet starting from the originating node is examined by the next active node if it is addressed to that node. If it does, it is copied, otherwise it is regenerated and passed on to the next node until it reaches back the originating node and is discarded. The ability to regenerate data packets allows a ring topology to span far greater distance than bus or star topologies.
