Overview#
Token Ring is a Local Area Network (LAN) technology communications protocol.Token Ring uses a special three-byte frame called a "token" that travels around a logical "ring" of Network devices. This token passing is a channel access method providing fair access for all stations, and eliminating the collisions of contention-based access methods.
Introduced by IBM in 1984, it was then standardized with protocol IEEE 802.5 and was fairly successful, particularly in corporate environments, but gradually eclipsed by the later versions of Ethernet.
