`Token-ring networks
`
`A token-ring network is a local area network (LAN) topology that sends data in one direction throughout a specified number of
`locations by using a token.
`
`The token is the symbol of authority for control of the transmission line. This token allows any sending station in the network (ring) to
`send data when the token arrives at that location.
`
`Stations in a token-ring network are physically connected, typically in a star-wired ring topology, to a wiring concentrator such as the
`IBM® 8228 Multistation Access Unit. The concentrator serves as a logical ring around which data is transmitted at 4 million, 16
`million, or 100 million bits per second (Mbps). Each station is connected to the concentrator typically by shielded twisted pair (STP)
`cabling.
`
`Full-duplex token ring
`In full-duplex token ring, which is also called DTR (dedicated token ring), switching hubs enable stations to send and
`receive data on the network simultaneously. A token-ring switching hub divides the network into smaller segments. When a
`station transmits its data packet, the token-ring switch reads the packet's destination address information and forwards the
`data directly to the receiving station. The switch then establishes a dedicated connection between the two stations,
`enabling data to be transmitted and received at the same time. In full-duplex token ring, the token-passing protocol is
`suspended. The network in effect becomes a 'tokenless' token ring. Full-duplex token ring increases sending and receiving
`bandwidth for connected stations, improving network performance.
