The set of nodes are connected by means of ring which is the token band. Its an individual distributed medium. Each node in the network transmits the info carrying out a distributing algorithm. Every body of the info is examined by every node, where in fact the vacation spot node saves a backup as in the data body header of the structure as it goes by. If any devices in the network fail it renders the whole network which is get over by the celebrity topology. In this star topology it is linked centrally to a token engagement ring hub. The Multi-station Access unit (MAU) is the hub which in conditions works as a relay. These units are required for the robustness and any change in the composition of the network like addition and removal of nodes. A special collection of pieces circulating throughout the network is thought as the Token, wherein each node receives and forwards the token.
