Abstract
There are disclosed a method and apparatus for reordering sequenced data packets. An expiration time is calculated for each received data packet. The expiration time and a packet sequence number are stored in a table. The table is read to determine the next data packet to be transmitted in sequence number order. The next data packet is output if available. If the next data packet is not available, a true expiration time is determined for the unavailable next data packet. If the unavailable next data packet fails to arrive before a current time is greater than the expiration time of the unavailable data packet, the unavailable next data packet is considered lost.
