From 9772efb970780aeed488c19d8b4afd46c3b484af Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 10 Nov 2005 17:09:53 -0800 Subject: [TCP]: Appropriate Byte Count support This is an updated version of the RFC3465 ABC patch originally for Linux 2.6.11-rc4 by Yee-Ting Li. ABC is a way of counting bytes ack'd rather than packets when updating congestion control. The orignal ABC described in the RFC applied to a Reno style algorithm. For advanced congestion control there is little change after leaving slow start. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
