The problem in the process of traffic cleaning is that the current DDOS attacks present a mixed attack state with multiple attack methods coexisting. In this case, how to efficiently detect attacks is the main problem currently facing. After consulting numerous data, Huawei's "seven-layer cleaning plan" is found to be very enlightening.
