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.

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 ``[milliseconds]``
- 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
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: console

# 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
'''''''''''''''''''''''''''''''''''''''''''''''''''
.. code-block:: console

# tcset --device eth0 --delay 100ms


Set 10 seconds network latency
'''''''''''''''''''''''''''''''''''''''''''''''''''
.. code-block:: console

# tcset --device eth0 --delay 10sec

Set 0.5 minutes (30 seconds) network latency
'''''''''''''''''''''''''''''''''''''''''''''''''''
.. code-block:: console

# tcset --device eth0 --delay 0.5min

e.g. Set 0.1% packet loss
^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: console

# tcset --device eth0 --loss 0.1

e.g. All of the above at once
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: console

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

e.g. Specify the IP address of traffic control
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: console

# tcset --device eth0 --delay 100 --network 192.168.0.10

e.g. Specify the IP network and port of traffic control
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: console

# 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:

.. code-block:: console

# 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
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: console

# 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"
}
}
}
}

Installation
============

Installing from PyPI
------------------------------
``tcconfig`` can be installed from `PyPI <https://pypi.python.org/pypi>`__ via
`pip <https://pip.pypa.io/en/stable/installing/>`__ (Python package manager) command.

.. code:: console

sudo pip install tcconfig


Installing from files
------------------------------
The following package includes ``tcconfig`` and dependency packages.
This package is for environments which cannot access to
`PyPI <https://pypi.python.org/pypi>`__ directly.

How to install:

1. Navigate to ``https://github.com/thombashi/tcconfig/releases/``
2. Download the latest version of ``tcconfig_wheel.tar.gz``
3. Copy ``tcconfig_wheel.tar.gz`` to installation target
4. ``tar xvf tcconfig_wheel.tar.gz``
5. ``cd tcconfig_wheel/``
6. ``./install.sh``


Dependencies
============

Linux packages
--------------
- ``iproute``/``iproute2``/``iproute-tc`` (mandatory: required for ``tc`` command)
- ``iptables`` (optional: required to when you use ``--iptables`` option)

Linux kernel module
----------------------------
- ``sch_netem``

Python packages
---------------
Dependency python packages are automatically installed during
``tcconfig`` installation via pip.
