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.　　由赵亮担纲的纪晓岚将“风流”与“纵横才气”有机地结合在一起，突破了以往的戏路；有中国最年轻“皇帝小生”之称的朱磊则将弘历这个重情重义的皇帝演绎得丝丝入扣，而初上　　1944年6月，联军在诺曼第成功登陆，成为联军战胜的转折点，美军得以将战力转向太平洋，六月登陆塞班岛，七月登陆关岛，麦克阿瑟将军随即又第二度踏上菲律宾国土。日本死守硫磺岛，军力约两万一千人，美军共出动三个师团75000人，舰船495艘，其他尚有驱逐舰，航空母舰等155艘，全力攻击硫磺岛。本纪录片为美军第三司令部摄影队冒死拍摄完成，为当今世上仅存，最忠实纪录第二次世界大战，“血战硫磺岛”之唯一史料！刚才有人看见她出来，往这边来，想是去后院了。
