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.三姐对我很好。This Lv Meng has just calculated 7600 attack power, causing 0.5% additional damage per general attack.武林兵器谱，江湖百晓生；飞刀称小李，千里惊鬼神！再现武侠巨匠古龙的飞刀外传，他是一个最强的江湖一流刀客，却也是一个最失意伤心的断肠人，就如同多情刀客无情刀一般，本身就是一个矛盾的组合，却又如此的吸引人。That's horrible! ! ! ! !
