Ring networks tend to be totally time consuming and inefficient when compared to client/server networks because the transmited data must travel through more points before reaching its destination. If I am not mistaken it's one of the most expensive network to maintain !!

In ring network, a token moves in a circular path within the ring.any system which wants to send data asks for the token.if the token is free, it is issued to the demanding system.if token is not available, the demanding system waits for the other system to finish.advantage is no two systems can send data at a single point of time unlike bus network.

Advantages:


One of the advantages of ring networks is that they can span larger distances than other types of networks, such as bus networks, because each node regenerates messages as they pass through it.

Adding additional nodes has very little impact on bandwidth.

It prevents network collisions because of the media access method or architecture required.


Disadvantage:

A ring network is a network topology where each node is connected to two other nodes, so as to create a ring. Ring networks tend to be inefficient when compared to Star networks because data must travel through more points before reaching its destination. For example, if a given ring network has eight computers on it, to get from computer one to computer four, data must travel from computer one, through computers two and three, and to its destination at computer four. It could also go from computer one through eight, seven, six, and five until reaching four, but this method is slower because it travels through more computers. Ring networks also carry the disadvantage that if one of the nodes in the network breaks down then the entire network will break down with it as it requires a full circle in order to function. The token ring network is a ring topology only at the logical level, it runs on a physical Star network, using central devices called MSAUs or MAUs
