From 9528592ff8d7ff361da430285deba8196e8984d5 Mon Sep 17 00:00:00 2001 From: Susant Sahani Date: Thu, 14 Aug 2014 14:31:47 +0530 Subject: socket: add support for TCP fast Open TCP Fast Open (TFO) speeds up the opening of successiveTCP) connections between two endpoints.It works by using a TFO cookie in the initial SYN packet to authenticate a previously connected client. It starts sending data to the client before the receipt of the final ACK packet of the three way handshake is received, skipping a round trip and lowering the latency in the start of transmission of data. --- man/systemd.socket.xml | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'man/systemd.socket.xml') diff --git a/man/systemd.socket.xml b/man/systemd.socket.xml index 352825f580..170d010f60 100644 --- a/man/systemd.socket.xml +++ b/man/systemd.socket.xml @@ -498,6 +498,21 @@ . + + FastOpen= + Takes a boolean + argument.
