linuxnet.qos: a Python package for managing Linux QoS using tc¶
Release v3.3.6.
linuxnet.qos provides programmatic access to the tc(8) command. Using linuxnet.qos one can manipulate the Linux Traffic Control functionality (queuing disciplines).
Accessing an interface’s queuing discipline configuration:
>>> from linuxnet.qos import QDiscConfig
>>> config = QDiscConfig('eth2')
>>> config.dump()
PFifoFastQDisc(0:0) root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
PFifoFastQDisc is the Python class used to represent the
pfifo_fast queuing discipline (see tc-pfifo_fast(8)).
Replacing the interface’s root queuing discipline:
>>> from linuxnet.qos import NetemQDisc, Handle
>>> netem_qdisc = NetemQDisc(Handle(1,1), None, delay=30.0)
>>> config.create_qdisc(netem_qdisc)
>>> config.dump()
NetemQDisc(1:1) root delay 30.0ms
Deleting the existing queuing discipline configuration:
>>> config.delete_config()
>>> config.read_interface_config()
True
>>> config.dump()
PFifoFastQDisc(0:0) root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
