Description
Specifies the time interval that defines the end of a segment stream. When this interval elapses between the receipt of TCP segments, TCP considers the segment stream to be complete, and it sends an ACK message to acknowledge the segment. Otherwise, TCP acknowledges every other segment only.
This interval is used in TCP's delayed acknowledgment strategy, in accordance with RFC 1122, Requirements for Internet hosts—communication layers.
