Simple tc command wrapper. Easy to setup traffic control of network bandwidth/latency/packet-loss to a network interface.

Project description



tcconfig is a Simple tc command wrapper. Easy to set up traffic control of network bandwidth/latency/packet-loss to a network interface.

Traffic control features


Traffic control can be specified network to apply to:

  • Outgoing/Incoming packets
  • Certain IP address/network and port

Available parameters

The following parameters can be set to network interfaces.

  • Network bandwidth rate [G/M/K bps]
  • Network latency [milliseconds]
  • Packet loss rate [%]
  • Packet corruption rate [%]


Set traffic control (tcset command)

tcset is a command to impose traffic control to a network interface (device).

e.g. Set a limit on bandwidth up to 100Kbps

# tcset --device eth0 --rate 100k

e.g. Set 100ms network latency

# tcset --device eth0 --delay 100

e.g. Set 0.1% packet loss

# tcset --device eth0 --loss 0.1

e.g. All of the above at once

# tcset --device eth0 --rate 100k --delay 100 --loss 0.1

e.g. Specify the IP address of traffic control

# tcset --device eth0 --delay 100 --network

e.g. Specify the IP network and port of traffic control

# tcset --device eth0 --delay 100 --network --port 80

Delete traffic control (tcdel command)

tcdel is a command to delete traffic control from a network interface (device).

e.g. Delete traffic control of eth0

# tcdel --device eth0

Display traffic control configurations (tcshow command)

tcshow is a command to display traffic control to network interface(s).


# tcset --device eth0 --delay 10 --delay-distro 2  --loss 0.01 --rate 0.25M --network --port 8080
# tcset --device eth0 --delay 1 --loss 0.02 --rate 500K --direction incoming
# tcshow --device eth0
    "eth0": {
        "outgoing": {
            "network=, port=8080": {
                "delay": "10.0",
                "loss": "0.01",
                "rate": "250K",
                "delay-distro": "2.0"
            "network=": {}
        "incoming": {
            "network=": {
                "delay": "1.0",
                "loss": "0.02",
                "rate": "500K"
