I. INTRODUCTION to TCTC, or traffic control, as the name implies, TC is a tool for the flow control of Linux. With TC, you can control the rate at which the network interface sends data.Each network interface (for example: ETH0,PPP0) has a queue that manages and dispatches data to be sent. TC works by setting different typesNetwork interface queue, which changes the rate and priority of packet transmission, to achieve the purpose of

In the past, many firewalls detected DDoS attacks based on a pre-set traffic threshold, exceeding a certain threshold, and generating an alarm event.The finer ones may set different alarm curves for different flow characteristics ., so that when an attack occurs suddenly, such as a SYN Flood, the SYN message in the network will exceed the threshold, indicating that a SYN flood attack has occurred.But when the message rate in the network itself is the
