What are the types of DDOS attacks?

There are two main types of DDOS: 1. Traffic attacks are mainly aimed at network bandwidth, that is, a large number of attack packets block the network bandwidth, and legitimate network packets are full of false attack packets, which cannot reach the host; 2. The resource exhaustion attack is mainly aimed at the server host, that is, a large number of attack packets lead to the exhaustion of the host memory or the CPU being occupied by the kernel and applications, which leads to the inability to provide network services.
