Scalable as leaf nodes can accommodate more nodes in the hierarchical chain. Even though a tree topology is not so commonly used network topology, it is still followed in certain circumstances when scalability or hierarchical communication setup is needed between two networks.
A survey of computer network topology and analysis examples brett meador, brett. The tree topology is useful in cases where a star or bus cannot be implemented individually. If the backbone line breaks, the entire segment goes down. Advantages and disadvantages of tree topology perfect. The most significant weakness of tree topology is the root node. Hybrid topology is a combination of more than two topologies. Advantages and disadvantages it has a root node and all other nodes are connected to it forming a hierarchy. Tree topology is used for the expansion of an existing network. The groups are then connected to a bus backbone cable. The section where fault is found could possibly be singled out from the rest of network and required restorative steps could be taken, without impacting the working of rest of the network. Dual ring topologies provide each node with two connections, one in each direction. Its disadvantages, on the other hand, include limit on central cable length and number of nodes.
