Immediately afterwards, the kernel tries to Whenever the kernel needs to sendĪ packet to an interface, it is enqueued to the qdisc configuredįor that interface. QDISCS top qdisc is short for 'queueing discipline' and it is elementary to Processing of traffic is controlled by three kinds of objects: Traffic exceeding a set bandwidth may also be droppedįorthwith, both on ingress and on egress. Whereas shaping deals with transmission of traffic, Is also called prioritizing, and happens only on egress. Still guaranteeing bandwidth to bulk transfers. To improve interactivity for traffic that needs it while Shaping occurs onīy scheduling the transmission of packets it is possible Shaping may be more than lowering the availableīandwidth - it is also used to smooth out bursts in When traffic is shaped, its rate of transmission is underĬontrol. Traffic Control consists of the following: Tc qdisc ĭESCRIPTION top Tc is used to configure Traffic Control in the Linux kernel.
