Project description

tcconfig

Summary

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

Linux CI test status GitHub repository

Traffic control features

Traffic shaping target

Apply traffic shaping rules to specific targets:

  • Outgoing/Incoming packets
  • Source/Destination IP-address/network (IPv4/IPv6)
  • Source/Destination ports

Moreover, exclude from shaping rules from specific targets:

  • Source/Destination IP-address/network (IPv4/IPv6)
  • Source/Destination ports

Available parameters

The following parameters can set to network interfaces:

  • Network bandwidth rate [G/M/K bps]
  • Network latency [microseconds/milliseconds/seconds/minutes]
  • Packet loss rate [%]
  • Packet corruption rate [%]
  • Packet duplicate rate [%]
  • Packet reordering rate [%]

Usage

Set traffic control (tcset command)

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

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

# tcset --device eth0 --rate 100k

e.g. Set network latency

You can use time units (such as us/sec/min/etc.) to designate delay time.

Set 100 milliseconds network latency
# tcset --device eth0 --delay 100ms
Set 10 seconds network latency
# tcset --device eth0 --delay 10sec
Set 0.5 minutes (30 seconds) network latency
# tcset --device eth0 --delay 0.5min

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 192.168.0.10

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

# tcset --device eth0 --delay 100 --network 192.168.0.0/24 --port 80

Delete traffic control (tcdel command)

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

e.g. Delete traffic control of eth0

You can delete all of the shaping rules for the eth0 with -a/--all option:

# tcdel --device eth0 --all

Display traffic control configurations (tcshow command)

tcshow is a command to display the current traffic control settings for network interface(s).

Example

# tcset --device eth0 --delay 10 --delay-distro 2  --loss 0.01 --rate 0.25M --network 192.168.0.10 --port 8080
# tcset --device eth0 --delay 1 --loss 0.02 --rate 500K --direction incoming
# tcshow --device eth0
{
    "eth0": {
        "outgoing": {
            "dst-network=192.168.0.10/32, dst-port=8080": {
                "delay": "10.0",
                "loss": "0.01",
                "rate": "250K",
                "delay-distro": "2.0"
            },
            "dst-network=0.0.0.0/0": {}
        },
        "incoming": {
            "dst-network=0.0.0.0/0": {
                "delay": "1.0",
                "loss": "0.02",
                "rate": "500K"
            }
        }
    }
}
