Title : Using TCP Selective Acknowledgement (SACK) Information to Determine Duplicate Acknowledgements for Loss Recovery Initiation
Author(s) : I. Jarvinen, M. Kojo
Filename : draft-jarvinen-tcpm-sack-recovery-entry-01.txt
Pages : 15

This document describes a TCP sender algorithm to trigger loss
recovery based on the information gathered on a SACK scoreboard
instead of simply counting the number of arriving duplicate
acknowledgements 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.
