Patent ID: 7792014

Claim:
A retry packet storing and selective bypassing method comprising: (a) using a less significant portion of a sequence number assigned to a first packet stored in a replay buffer for generating a first index signal referencing a first location of an index table; (b) determining a start address assigned to the stored first packet within the replay buffer; (c) recording the determined start address or an indirect pointer to that determined start address of the first packet in the first location of the index table such that the start address or other pointer is retrievable from the index table by using the generated first index signal as a reference to the first location; (d) using the index table to locate within, and replay from the replay buffer, one or more packets that have been once-played-out-but-not-yet-acknowledged; and (e) in response to detection that the first packet has been nullified, overwriting the start address or indirect pointer in the index table so as to thereby prevent the nullified first packet from being replayed from the replay buffer after the nullified state of the first packet is detected.
