Emulating wide area network delays
Add delay of 100ms:
tc qdisc add dev eth0 root netem delay 100ms
Remove delay:
tc qdisc change dev eth0 root netem delay 0ms
Change delay to 1000ms:
tc qdisc change dev eth0 root netem delay 1000ms
Add random variation to 100ms delay of +/- 10ms:
tc qdisc change dev eth0 root netem delay 100ms 10ms
Add random variation to 100ms delay of +/- 10ms with 25% correlation:
tc qdisc change dev eth0 root netem delay 100ms 10ms 25%
