  • Why you want QoS - Netdata Documentation — One of the features the Linux kernel has, but it is rarely used, is its ability to apply QoS on traffic. Even most interesting is that it can apply QoS to both inbound and outbound traffic.
  • FireQOS Wiki — FireQOS is a helper to assist you configure traffic shaping on Linux.
  • FireHOL - Linux firewalling and traffic shaping for humans — FireHOL is a language (and a program to run it) which builds secure, stateful firewalls from easy to understand, human-readable configurations. The configurations stay readable even for very complex setups.
  • tc(8) man page — Traffic Control consists of the following: SHAPING When traffic is shaped, its rate of transmission is under control. Shaping may be more than lowering the available bandwidth - it is also used to smooth out bursts in traffic for better network behaviour. Shaping occurs on egress. SCHEDULING By scheduling the transmission of packets it is possible to improve interactivity for traffic that needs it while still guaranteeing bandwidth to bulk transfers. Reordering is also called prioritizing, and happens only on egress. POLICING Where shaping deals with transmission of traffic, policing pertains to traffic arriving. Policing thus occurs on ingress. DROPPING Traffic exceeding a set bandwidth may also be dropped forthwith, both on ingress and on egress.
  • Overview of Traffic Control Concepts — Traffic control is the name given to the sets of queuing systems and mechanisms by which packets are received and transmitted on a router. This includes deciding which (and whether) packets to accept at what rate on the input of an interface and determining which packets to transmit in what order at what rate on the output of an interface.
  • Advanced traffic control - ArchWiki
  • Journey to the Center of the Linux Kernel: Traffic Control, Shaping and QoS — This document describes the Traffic Control subsystem of the Linux Kernel in depth, algorithm by algorithm, and shows how it can be used to manage the outgoing traffic of a Linux system.
  • Netdata Real-time performance monitoring, done right! — Netdata is distributed, real-time, performance and health monitoring for systems and applications. It is a highly optimized monitoring agent you install on all your systems and containers.
  • Add more charts to netdata — To collect non-system metrics, netdata supports a plugin architecture.
