TC - Traffic Control

The Linux kernel's network stack has network traffic control and shaping features. The iproute2 package installs the tc command to control these via the command line.
Queuing controls how data is sent; receiving data is much more reactive with fewer network-oriented controls. However, since TCP/IP packets are sent using a slow start the system starts sending the packets slow and keeps sending them faster and faster until packets start getting rejected - it is therefore possible to control how much traffic is received on a LAN by dropping packets that arrive at a router before they get forwarded. There are more relevant details, but they do not touch directly on queuing logic.
