From 1e757f9996114f713a79d3fbcd08739efcfc5c34 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ilpo=20J=C3=A4rvinen?= Date: Mon, 30 Jul 2007 19:48:37 -0700 Subject: [PATCH] [TCP]: Fix ratehalving with bidirectional flows MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Actually, the ratehalving seems to work too well, as cwnd is reduced on every second ACK even though the packets in flight remains unchanged. Recoveries in a bidirectional flows suffer quite badly because of this, both NewReno and SACK are affected. After this patch, rate halving is performed for ACK only if packets in flight was supposedly changed too. Signed-off-by: Ilpo Järvinen Signed-off-by: David S.
