Net on tree

The tree network is a network topology in which the nodes are arranged in the form of a tree. From a topological perspective, it is similar to a series of interconnected star networks except that it does not have a central hub. Instead, it has a trunk node, usually occupied by a hub or switch, from which the other nodes branch out. It is a variation of the bus network, the failure of a node does not imply an interruption in communications. The same communication channel is shared.

The tree topology can be seen as a combination of several star topologies. Both the tree and the star are similar to the bus when the interconnection node works in broadcast mode, since the information is propagated to all the stations, only that in this topology the branches extend from a root point (star), to as many ramifications as possible, according to the characteristics of the tree.

The problems associated with the previous topologies are that the data is received by all the stations regardless of who they are intended for. It is then necessary to provide the network with a mechanism that allows the recipient of the messages to be identified, so that they can collect them upon arrival. In addition, due to the presence of a shared transmission medium among many stations, interference between signals may occur when two or more stations transmit at the same time. It is the best network topology that exists and with it data flows faster than in other types of network topologies.

Disadvantages of Tree Topology

• A lot of cable required
• It is unreliable for distributed companies
• The measurement of each segment is determined by the type of cable used.
• If the main segment falls, the entire segment also falls.
• It's harder to set up.
• If a node was disconnected, all those connected to it are also disconnected.
