Re: tc qdisc red?
For those wanting to actually try things on their computers:
For windows: (All these settings require the “Run As Administrator” permission)
To show the current state of the TCP settings:
netsh int tcp show global
To turn on ECN:
netsh int tcp set global ecncapability=enabled
To turn on cTCP:
netsh int tcp set global congestionprovider=ctcp
Fedora 20 (possibly other Linux based systems):
To turn on ECN to help feedback to the AQM in the file: /etc/sysctl.conf add the following line:
net.ipv4.tcp_ecn = 1
To alter the Active Queue Management scheduler alter the following file: /etc/rc.d/rc.local and add the following line:
tc qdisc add dev eth0 root fq_codel
replacing eth0 with the name of the computers network device. Then reboot.
