Token Ring

Token Ring is a LAN network technology provided by IBM. It was introduced by IBM in 1984 and standardized as IEEE 802.5 in 1989.

As the name implies, it uses a token-passing methodology for arbitration on a physical ring topology.

Original 1985 Token Ring provided 4 Mbit/s speed, while the later 1988 IEEE standard provided 16 Mbit/s.
