[NETFILTER]: x_tables: add rateest match
Add rate estimator match. The rate estimator match can match on
estimated rates by the RATEEST target. It supports matching on
absolute bps/pps values, comparing two rate estimators and matching
on the difference between two rate estimators.
This is what I use to route outgoing data connections from a FTP
server over two lines based on the available bandwidth:
# estimate outgoing rates
iptables -t mangle -A POSTROUTING -o eth0 -j RATEEST --rateest-name eth0 \
--rateest-interval 250ms \
--rateest-ewma 0.5s
iptables -t mangle -A POSTROUTING -o ppp0 -j RATEEST --rateest-name ppp0 \
--rateest-interval 250ms \
--rateest-ewma 0.5s
# mark based on available bandwidth
iptables -t mangle -A BALANCE -m state --state NEW \
-m helper --helper ftp \
-m rateest --rateest-delta \
--rateest1 eth0 \
--rateest-bps1 2.5mbit \
--rateest-gt \
--rateest2 ppp0 \
--rateest-bps2 2mbit \
-j CONNMARK --set-mark 0x1
iptables -t mangle -A BALANCE -m state --state NEW \
-m helper --helper ftp \
-m rateest --rateest-delta \
--rateest1 ppp0 \
--rateest-bps1 2mbit \
--rateest-gt \
--rateest2 eth0 \
--rateest-bps2 2.5mbit \
-j CONNMARK --set-mark 0x2
iptables -t mangle -A BALANCE -j CONNMARK --restore-mark
