The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.

"Teacher, when I synthesize crystals, I need to find different conditions to synthesize them, but there are too many tests. Do you have any better methods?" "What do you synthesize crystals for?" "Of course, it is to test its performance." "Then why do we stick to the need to synthesize crystals before testing properties? We can test properties with the results of each time. Maybe we can find better substances, can't we?" "Ah! Yes, thank you, teacher, I'll try it!" In an exchange with Mr. Sun Yimin, the teacher proved once again the correctness of the sentence "Don't stick to books and documents" while solving the problems of the team members.
