Hierarcy Topology

Computer network topology has a variety of types, one of which is the hierarchy topology. Hierarchy topology is a computer network topology that has a shape like a branching tree. This topology is an extension or wide version of the star topology. In this topology each node has a relationship with the other nodes, the nodes that have a high level will be placed at the top while the lower nodes will be stored below. Like a tree in this topology every node can think of a branch that is other nodes.


In the process of data transmission, the data sent must first through the node is located above the node which becomes the branch central node to achieve the purpose of sending messages. With this system, if the branch central node is damaged it will hamper the process of sending data, especially on nodes that are farthest in a network.

Then what are the advantages and disadvantages of the hierarchy topology? Of course every topology will have its own deficiencies and advantages. To find out if this topology matches or not with the network you are about to build, here are the advantages and disadvantages of the hierarchy topology.

The advantage of the hierarchy topology is that it is easy to manage each node, this is because of the central nodes at each level. Another advantage is the hierarchy topology can reach a very long distance because of the repeater that becomes the signal amplifier at each hub.

The disadvantage of the hierarchy topology is that if a node breaks it will interfere with the node node underneath it. Then in the process of installation requires a lot of cables, so it must be able to design carefully to minimize the use of unnecessary cable. And the last is often the collision of data when the data transmission process is in progress.
