IT Interview Questions: Token Ring Topology
Token Ring is the second most widely used LAN technology after Ethernet, where all computers are connected in a logical ring topology. Physically, each host attaches to an MSAU (Multistation Access Unit) in a star configuration. MSAU’s can be chained
together to maintain the logical ring topology. An empty frame called a token is passed around the network. A device on the network can transmit data only when the empty token reaches the device. This eliminates collisions on a Token Ring network. Token Ring uses MAC addresses just like any other LAN technology. The Token Ring interfaces on a non-modular router are To0, To1, To2 and so on. ?To? stands
for Token Ring and the number following ?To? signifies the port number. In a modular
router, ?To? will be f ollowed by the slot number/port number
