Token Ring networks use a special three-byte frame called a token that travels unidirectionally around a star-wired logical ring. Token ring frames travel completely around the ring in a counter-clockwise direction. Each Stations passes or repeats the special token frame around the ring to its nearest upstream neighbor. This token-passing process is used to arbitrate access to the shared ring media. Stations that have data frames to transmit must first acquire the token before they can transmit them. Token ring LANs use differential manchester encoding of bits on the LAN media.

IBM popularized the use of Token Ring LANs in the mid 1980's when it released its IBM Token Ring architecture based on active multi-station access units (MSAUs or MAUs) and the IBM Structured Cabling System. The Institute of Electrical and Electronics Engineers or IEEE (http://www.ieee.org) later standardized a token ring LAN system as IEEE 802.5 (http://www.8025.org).

Token ring networks have since declined in usage and the standards activity has since come to a standstill as competing technologies such as Ethernet (IEEE 802.3) have dominated the LAN/layer 2 networking market.
