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.Netflix正式预定《黑钱胜地》第三季！该剧由杰森·贝特曼、劳拉·琳妮等主演，剧集主要讲述了贝特曼饰演理财师马蒂·伯德(贝特曼饰)与其妻子温迪(琳尼饰)一家突然从芝加哥郊区搬到奥沙克湖的度假胜地，并必须还清墨西哥毒枭的债。Secondly, it is suggested that if the feedback of the problem is not implemented according to the requirements determined by the discussion, the responsible person or the competent leader of the department concerned should implement the accountability system in addition to the performance appraisal.C.
