Abstract

See full text

A method includes determining a priority of each of a plurality of frames, wherein the priority is a function of an initial value dependent on content of each said frame and one or more adjustment values independent of content of each said frame, and selecting the frame with the highest determined priority for transmission through the device prior to transmission of any other of the frames. A system includes a receiving port configured to receive frames and assign an initial priority to each frame, a queue configured to insert queue entries associated with received frames on the queue, each queue entry being inserted at a queue position based on the initial priority assigned to the queue entry, the queue further configured to reorder queue entries based on readjusted priorities of the queue entries; and a transmitter switch configured to transmit the frame having the highest priority before transmitting any other frame.
