Understanding Traffic Control
Traffic control, commonly referred to as TC, regulates traffic on local hosts. Traffic control is responsible for controlling the flow of traffic based on a given flow's priority, both from an internal perspective (within the kernel itself), and from a network perspective (prioritization and queuing of packets based on transmission priority).
The following sections detail how traffic control is invoked, how traffic control settings can be checked, and how to programmatically modify how traffic control treats a given flow.
