Chapter 6. Token Ring/IEEE 802.5
Two standard LANs use Token Ring: IEEE 802.5 and FDDI. This chapter discusses the IEEE 802.5-based implementations.
The term Token Ring is generally used to refer to both IBM's Token Ring and IEEE 802.5 network implementations. IBM originally developed the Token Ring network in the 1970s, and it is still IBM's primary local-area network (LAN) technology. The related IEEE 802.5 specification is almost identical and completely compatible with IBM's Token Ring network implementations. The IEEE 802.5 specification was modeled after IBM's Token Ring specification, and the IEEE 802.5 specification continues to follow IBM's research and developmental work with Token Ring.
Although the Token Ring and IEEE 802.5 ...
