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.According to the memory of Liu Guangyuan, a soldier who personally participated in the battle that year:只愿残酷的战争之后，能迎来长久的美好，这个信念也是支持杨长帆最大的信念，他必须坚信自己的所作所为，即便过程中有一些不那么美好的地方。Reusability但是无可奈何之下，只得做出一个牺牲和取舍。
