Abstract

See full text

A transport protocol data flow reconstruction method delays determination that a missing packet is lost for a period of time. For an evaluated TCP packet in a first direction, the method determines if a TCP packet is missing in a second direction, in which case the method stores the evaluated TCP packet in a list and creates an acknowledgement timer indicating a maximum time to wait until treating the missing TCP packet as lost. Expiration of the acknowledgment timer indicates a missing packet in the second direction. The method determines if a TCP packet is missing in the first direction, in which case the method stores the evaluated TCP packet in the list and creates a retransmission timer indicating a maximum time to wait until treating the missing TCP packet as lost. Expiration of the retransmission timer indicates a missing packet in the first direction.
