Setting up queuing systems on Linux depends on interaction with the Linux Traffic Control (tc) subsystem, for which very limited documentation exists. The Linux Advanced Routing & Traffic Control HOWTO is one of the principal documents serving as the starting point for most QoE solutions currently available, LibreQoS included. Its authors include:

  • Phil Sutter
  • Bert Hubert
  • Gregory Maxwell
  • Remco van Mook
  • Martijn van Oosterhout
  • Paul B Schroeder
  • Jasper Spaans
