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.
In Bus Network Topology a single cable is used to connect all devices on the net. This cable is often referred to as the network Backbone. When communication occurs between nodes the device sending the message broadcasts to all nodes on the network, but only the desired recipient digests the message.ince Logical Network Topology builds upon the underlying Network Physical Topology the set of standard computer physical topologies will reviewed first as background to the performance analysis discussion. This will be followed by a brief description of Graph Theory, and then the network analysis examples.
