摘要：An FDDI system and method for transmitting to an optical medium, uponreceipt of token, frames of synchronous data and frames of asynchronous data havingdifferent levels of priority. The network on which the FDDI is implemented includes aplurality of processors each having a system memory for storing the frames of data inqueues corresponding to priority, and an output buffer configured to have a plurality oflogical FIFOs corresponding to the queues. Data is transferred one queue at a time fromthe system memory to the output buffer through a single physical FIFO. To prevent theFIFO from \"locking-up\" as a result of any residual data remaining therein following eachtransfer of a frame to the output buffer, storage remaining available for a particularqueue of the output buffer to be transmitted to the medium is detected. Data istransferred from the system memory to the FIFO memory only if the storage remainingavailable is at least equal to the storage capacity of the FIFO memory.
