Abstract
System for reordering sequenced based packets in a switching network. The system includes time stamp logic that operates to associate a receive time indicator with each received data packet. The system also includes Enqueue logic that operates to compute an expiration time for each received packet based on the receive time indicator, and stores the expiration time and the sequence identifier for each received packet into a table. Dequeue logic operates to read the table to determine the received data packets to output in an output stream so that the received data packets are output in a selected order. The Dequeue logic also operates to determine a true expiration time for one or more unreceived data packets, and if the true expiration time for a selected unreceived data packet is reached, the Dequeue logic operates to omit the selected unreceived data packet from the output stream.
