From 7c106d7e782bd4805f39da30e81018f861b4b8c5 Mon Sep 17 00:00:00 2001 From: Wong Hoi Sing Edison Date: Mon, 5 Jun 2006 17:27:58 -0700 Subject: [TCP]: TCP Low Priority congestion control TCP Low Priority is a distributed algorithm whose goal is to utilize only the excess network bandwidth as compared to the ``fair share`` of bandwidth as targeted by TCP. Available from: http://www.ece.rice.edu/~akuzma/Doc/akuzma/TCP-LP.pdf Original Author: Aleksandar Kuzmanovic See http://www-ece.rice.edu/networks/TCP-LP/ for their implementation. As of 2.6.13, Linux supports pluggable congestion control algorithms. Due to the limitation of the API, we take the following changes from the original TCP-LP implementation: o We use newReno in most core CA handling. Only add some checking within cong_avoid. o Error correcting in remote HZ, therefore remote HZ will be keeped on checking and updating. o Handling calculation of One-Way-Delay (OWD) within rtt_sample, sicne OWD have a similar meaning as RTT. Also correct the buggy formular. o Handle reaction for Early Congestion Indication (ECI) within pkts_acked, as mentioned within pseudo code. o OWD is handled in relative format, where local time stamp will in tcp_time_stamp format.
