This part of ISO/IEC 9314 specifies the Media access control (MAC) , the middle sublayer of the data link layer (DLL) for fiber distributed data interface (FDDI) .FDDI (ISO/IEC 9314) provides a high -bandwidth (100 Mbit/s).general - purpose interconnection among information processing systems, subsystems and peripheral equipment , using fiber optics or other transmission media. FDDI can be configured to support a sustained data transfer rate of at least 80 Mbit/s (10 Mbytes/s). FDDI provides connectivity for many nodes distributed over distances of many kilometers in extent . Certain default parameter values for FDDDI (e.g. timer settings) are calculated on the basis of up to 1000 transmission links or up to 200 km total fiber path length (typically corresponding to 5000 nodes and 100 km of dual fiber cable, respectively), however, the FDDI protocols can support much larger networks by increasing these parameter values.
