6.4. 1? SYN? Generation of cookiesThe 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.灰太狼大王凭借自己的惊世发明拜拜机，抓到了总是比别人慢半拍的懒羊羊，得意洋洋的他无视正与懒羊羊开心互动的儿子小灰灰，围着大锅忙里忙外地煽风点火。突然一个奇怪的巨型铲子从天而降，把古怪扭曲的狼堡，挖掉了一大块。接下来发生的一切神奇而不可思议。灰大王竟然被挖到了另一个世界。在这个古怪、莫名其妙的地方，为了救宝贝儿子小灰灰，灰大王要展开了惊险刺激的冒险大逃亡。[1]沙加路很配合，与杨长帆走到一旁。正吵着，樱桃从厨房走出来，皱眉道：洗个碗也吵？小葱也从东厢出来，走到近前问道：啥事？樱桃笑道：没啥事，小女娃们拌嘴，我说她们了。等娃儿们都下了水，众人全都盯着黑鱼瞧。2248年，休眠的C40小队队长方毅（任天野 饰）和他的小队成员刘火（王韬 饰）、段依山（程汉 饰演）等被人工智能控制系统长夜之光唤醒，并将执行一项绝密任务——潜入基因药物研究中心，销毁所有药物及试验资料。而研究中心已经遭到Mr.Dee（丁海峰 饰）带领的黑羽会入侵，为了获得延长休眠的权限，C40小队必须接受这场生死行动……
