Fiber distributed data interface (FDDI) data link control (DLC FDDI) is a device manager that follows the generic interface definition (GDLC). This data link control (DLC) device manager provides a passthrough capability that allows transparent data flow as well as an access procedure to transfer four types of data over a FDDI network:
