Emulating a high latency network connection using Linux and TC Often it is necessary for testing purposes to recreate the networking conditions found in a high latency network, such as a satellite link. Firstly create a network bridge that can be placed inbetween the test network and its router. To increase network latency use the following command: tc qdisc add dev eth0 root netem delay 2000ms which will delay every IP packet going through the bridge by 2 seconds. To reset this delay and remove the 2 seconds of latency: tc qdisc del dev eth0 root viaEmulating a high latency network connection using Linux and TC.
