tree topology

TREE TOPOLOGY

A tree topology is essentially a combination of bus topology and star topology. The nodes of bus topology are replaced with standalone star topology networks. This results in both disadvantages of bus topology and advantages of star topology.For example, if the connection between two groups of networks is broken down due to breaking of the connection on the central linear core, then those two groups cannot communicate, much like nodes of a bus topology. However, the star topology nodes will effectively communicate with each other.It has a root node, intermediate nodes, and ultimate nodes. This structure is arranged in a hierarchical form and any intermediate node can have any number of the child nodes.

Tree Topology

Advantages :-

1. It is scalable. Secondary nodes allow more devices to be connected to a central node.
2. Point to point connection of devices.
3. Having different levels of the network makes it more manageable hence easier fault identification and isolation.

Disadvantages :-

1. Maintenance of the network may be an issue when the network spans a great area.
2. Since it is a variation of bus topology, if the backbone fails, the entire network is crippled.
