Abstract: A buffer switch comprises a data memory that stores a plurality of data. A cache memory comprises a plurality of FIFO mini-queues each storing a plurality of descriptors each corresponding to a respective one of the plurality of data. An output memory comprises a plurality of output queues. A burst writer simultaneously transfers M ones of the plurality of descriptors stored in a corresponding one of the plurality of mini-queues to at least a corresponding one of the plurality of output queues. The burst writer accesses the output memory, when the output memory is available, once for every M ones of the plurality of descriptors.

Abstract: A device for writing descriptors, the device including a local memory comprising a multiplicity of mini-queues, wherein each of the mini-queues temporarily stores a plurality of descriptors, wherein each of the descriptors is associated with one of the data packets. Additionally including an output memory comprising a multiplicity of output queues, wherein each of the output queues in output memory is associated with one of the queues in said local memory, and a burst writer which writes N descriptors simultaneously from the mini-queue in the local memory to its associated output queue in output memory.
