ISO/IEC 9314-26-ed.1.0

Die Annotation des Normtextes ISO/IEC 9314-26-ed.1.0 :

The Fibre Distributed Data Interface (FDDI) is intended for use in a high performance general-purpose multi-station 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 stations operating over an extent of tens of kilometers. The FDDI Media Access Control (MAC) standard, ISO/IEC 9314-2, specifies the lower sub-layer of the Data Link Layer for FDDI. It specifies access to the medium, including addressing, data checking and data framing. ISO/IEC 9314-2 also specifies the receiver and transmitter state machines. This part of ISO/IEC 9314 is an abstract test suite (ATS) conformance test for FDDI MAC. Since MAC is a protocol that deals primarily with complete PDUs, the Tree and Tabular Combined Notation TTCN language specified in ISO/IEC 9646-3 is used to specify MAC protocol tests.
