If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.

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.
