If an attack is detected, the management center will start a cleaning scheme to pull the mixed traffic of attack traffic and normal traffic through BGP, CDN, etc. Pull the mixed flow to the flow cleaning center for cleaning. 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. The scheme comprehensively analyzes data packets for mixed traffic through seven layers of defense measures such as static filtering, abnormal message filtering, scanning and snooping message filtering, source legitimacy authentication, session-based prevention, feature identification filtering and traffic shaping, so as to detect attack traffic to the greatest extent. The framework of Huawei's "seven-layer cleaning scheme" is shown in Figure 2. After the traffic is cleaned, the attack traffic is discarded, and the normal traffic is injected back into the network through MPLS, GRE tunnel technology, etc.

The reason why the logic for creating an object is put into a separate class is that it can be used by multiple clients. And separates the creation and use of objects. However, this design also has many defects. First of all, SimpleFactory is a specific class, so we must program for the implementation, making the system lose its flexibility in this respect. Second, if we add new products, we have to modify the code in SimpleFactory, which violates the opening and closing principle. The above model is also called simple factory. He does not appear in GOF mode, it is more like a programming habit.
