used for enterprise-level network topologies because of its high susceptibility to faults and system downtime. If a linkbetween routers becomes faulty, the whole network may get disrupted, as there are no alternate data transmissionroutes. Therefore, this type is only used in small network setups.Distributed BackboneThedistributed backbonenetwork comprises a hierarchical formation of devices that are adaptable to multipleconnectivity. For example, if multiple devices are connected to switches, these form the intermediary devicesconnecting to the backbone router and gateway devices.
The distributed backbone network, unlike the serial backbone network, is well suited for enterprise-wide connectivity.Expanding and troubleshooting the network is simple, as layers of the network are easily added and managed.Collapsed BackboneThecollapsed backbonenetwork makes use of a single, high specification router that serves as the centralconnection supporting the rest of the network. As the backbone, it's characterized by high computational power toadequately handle the traffic from various networks. With this setup, the entire network is dependent on this singlerouter, making the network extremely vulnerable. If the router goes down for any reason, so does the entire network.This type of backbone topology is mainly applicable in situations where two different types of sub networks need tobe connected and managed effectively.Parallel BackboneParallel backbonenetworks employ a system of replicated connections to the backbone infrastructure. In thissystem, nodes and switches are implemented with duplicate concurrent connections to the high-level backbonerouters. Not all nodes need to have the parallel connection, but strategic points of the network could be designed assuch.Because the connections function concurrently, network availability at all times is ensured. This setup also ensureshigh network speeds, robustness, and high fault tolerance. With this replicated setup, implementation costs getexpensive with the increased cabling. The parallel backbone is a variation of the collapsed backbone infrastructureused to connect and managed different types of sub networks effectively.Lesson SummaryBackbone networksare networks designed with high capacity connectivity infrastructure that form the main link, orbackbone, connecting the different parts of the network. The network consists of various LANs, WANs, and subnetworks. The backbone normally comprises of high specification routers and gateways.Different types of backbone networks include:Theserial backbone: uses two or more connected devices linked to each other by hubs. It's simple andeasy to implement but is only used in small network setups because of its high susceptibility to faults andsystem downtime.Thedistributed backbone: spans a larger network with multiple sub networks connected.
