Ring The ring topology connects workstations in a closed loop. Data is transmitted around the ring in one direction only, each station passing on the data to the next station till it reaches its destination. Ring Topology Faulty workstations can be isolated from the ring. When the workstation is powered on, it connects itself into the ring. When power is off, it disconnects itself from the ring and allows the information to bypass the workstation.
Information travels around the ring from one workstation to the next.
Each packet of data sent on the ring is prefixed by the address of the station to which it is being sent to. When a packet of data arrives, the workstation checks to see if the packet address is the same as its own. If it is, it grabs the data in the packet. If the packet does not belong to it, it sends the packet to the next workstation in the ring. The common implementation of this topology is token ring .
