linux router tc traffic control 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 getti…
