Article title: Traffic Control: iptables + tc. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Set the external address eth0: 192.168.1.223 in eth0 on the server. Eth1 helps set the internal address eth1: 1 192.168.2.1 The function to be implemented now is to limit the entire exit to 512 kbit (upload traffic), and

TC is a Linux-brought module that can be used to control the speed of the network.Common command formatsTC [Qdisc/class/filter] [add/del/replace] Dev Nic name other parametersThe TC speed limit is primarily the sending of packets to different types of queues, which are then controlled by the queue. The speed limit queue mainly consists of two kinds: one is the non-class queue, which includes Pfifo_fast (FIF
