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.刘氏爱怜地看着葫芦道：你这不是馋他么？这时候怕是还不能吃别的东西。葫芦先下车，见那两个披着华丽披风的少年从院内出来，回身就想嘱咐小葱跟秦淼等会下车，却来不及了。　　一天陈清告诉周渔，说他要去边疆支教。这一决定最终成全了周渔和张强，还是让周渔看清了该如何决断？贾杰侦探是个经过生化实验的半机器人，他全身上下装有14,000个精巧的机关，办案成绩卓著，一直是城市里最有名的侦探，坏心的克劳博士却要故意陷害贾杰，因此他必须想办法重振自己的声威。Yayao Town is located in Huadu District of Guangzhou City.
