Subject: [PATCH net-next 0/2] more accurate DSACK processing for RACK-TLP
Date: Tue, 27 Jul 2021 10:42:56 -0400	[thread overview]
Message-ID: <20210727144258.946533-1-ncardwell@google.com> (raw)

This patch series includes two minor improvements to tighten up the accuracy of
the processing of incoming DSACK information, so that RACK-TLP behavior is
faster and more precise: first, to ensure we detect packet loss in some extra
corner cases; and second, to avoid growing the RACK reordering window (and
delaying fast recovery) in cases where it seems clear we don't need to.

Neal Cardwell (1):
  tcp: more accurately check DSACKs to grow RACK reordering window

  tcp: more accurately detect spurious TLP probes
