	Title           : Using TCP Selective Acknowledgement (SACK) Information to Determine Duplicate Acknowledgements for Loss Recovery Initiation

This document describes a TCP sender algorithm to trigger loss
 recovery based on the TCP Selective Acknowledgement (SACK)
 information gathered on a SACK scoreboard instead of simply counting
 the number of arriving duplicate acknowledgements (ACKs) in the
 traditional way.  The given algorithm is more robust to ACK losses,
 ACK reordering, missed duplicate acknowledgements due to delayed
 acknowledgements, and extra duplicate acknowledgements due to
 duplicated segments and out-of-window segments. The algorithm allows
 not only a timely initiation of TCP loss recovery but also reduces
 false fast retransmits.  It has a low implementation cost on top of
 the SACK scoreboard defined in RFC 3517.
