Message-ID: <1307567005.3980.1.camel@edumazet-laptop> Date: Wed, 08 Jun 2011 23:03:25 +0200 From: Eric Dumazet <eric.dumazet@...il.com> To: Jerry Chu <hkchu@...gle.com> Cc: David Miller <davem@...emloft.net>, Hagen Paul Pfeifer <hagen@...u.net>, tsunanet@...il.com, "netdev@...r.kernel.org" <netdev@...r.kernel.org> Subject: Re: [PATCH] RFC2988bis + taking RTT sample from 3WHS for the passive open side Le mercredi 08 juin 2011 à 11:04 -0700, Jerry Chu a écrit : > [resent to cc netdev] > Well, the first copy I received this morning was OK ;) But this second one is mangled by your mailer or something ? > This patch lowers the default initRTO from 3secs to 1sec per > RFC2988bis. It falls back to 3secs if the SYN or SYN-ACK packet > has been retransmitted, AND the TCP timestamp option is not on. > > It also adds support to take RTT sample during 3WHS on the passive > open side, just like its active open counterpart, and uses it, if > valid, to seed the initRTO for the data transmission phase. > > The patch also resets ssthresh to its initial default at the > beginning of the data transmission phase, and reduces cwnd to 1 if > there has been MORE THAN ONE retransmission during 3WHS per RFC5681. > > Signed-off-by: H.K.
