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.他们互相残杀而死，尚书大人凭什么说是下官指使？王尚书喝道：若不是为了灭口，商平为何要杀妻？白凡冷笑道：下官若真要灭口，怎会容董小翠活着离开汪村，还生下惠灵？下官说过，是商平心思狠毒，要杀董小翠灭口，向下官表示忠心，并洗清失职之罪。该剧讲述了参与了24小时冷冻人类项目的男女，因为神秘的阴谋20年后才醒来时迎来的感人故事。池昌旭实验20年间作为冷冻人活着的异能局PD马东灿。这就结束了？无论是南雀军还是靖军，都陷入死寂，张大嘴巴看向山谷中央，只见那个少年俯身捡起阿图人头，高高举起，狂吼道：杀——手臂扬起处，从人头颈项中撒落一阵血雨，在阳光下闪耀着魅力色彩。How to answer such questions?

The more civilians want pineapple (make a spray point). Based on the first point, the current boss civilians can still participate and get a small reward. If there is an ordinary boss player with extreme high defense, there is no chance to reward white whoring.
