The Token Ring network was originally developed by IBM in the 1970s. It is still IBM s primary local-area network (LAN) technology. The related IEEE 802.5 specification is almost identical to and completely compatible with IBM s Token Ring network. In fact, the IEEE 802.5 specification was modeled after IBM Token Ring, and it continues to shadow IBM s Token Ring development. The term Token Ring generally is used to refer to both IBM s Token Ring network and IEEE 802.5 networks. This article addresses both Token Ring and IEEE 802.5.
