Advantage and disadvantage of ring topology

The ring topology is a local area network (LAN) topology in which the medium forms a loop to which workstations are attached. Data is transmitted in a simplex form from one station, normally employing a token-passing.

Advantages:

  • Easy to install
  • Easy to reconfigure the network (add and remove nodes but keep the ring intact)
  • Fault isolation is easy
Disadvantages:

  • All nodes suffer from high traffic.
  • A break in the ring may halt the network

Token ring

A computer network arbitration scheme in which conflicts in the transmission of messages are avoided by the granting of "tokens" which give permission to send. A station keeps the token while transmitting a message, if it has a
message to transmit, and then passes it on to the next station.

Often, "Token Ring" is used to refer to the IEEE 802.5 token ring standard, which is the most common type of token ring.
