ISO/IEC 9314-8 (1998-08)

The Fibre Distributed Data Interface (FDDI), ISO/IEC 9314, is intended for use in a high-performance general purpose multi-node network and is designed for efficient operation with a peak data rate of 100 Mbit/s. It uses a Token Ring architecture with optical fibre as the transmission medium. FDDI provides for hundreds of nodes operating over an extent of tens of kilometres. The Media Access Control (MAC) specifies the lower sublayer of the Data Link Layer for the FDDI. As such, it presents the specifications and services provided for conforming FDDI attachment devices. MAC specifies the access to the medium, including addressing, data checking, and data framing. MAC also specifies the receiver and transmitter state machines. This part of ISO/IEC 9314 for MAC-2 is an enhancement to the original FDDI standard on MAC (ISO 9314-2).
