[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 <akuzma@northwestern.edu>
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.
