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.23他们心照不宣地交换目光，心下掂掇：这两小子难道曾经考过秀才？嘴皮子这么利索，咋一点都不像带兵打仗的军大爷呢？何霆懒懒地靠在虎皮交椅上，心神放松的同时，觉得有些困倦。怎么可能？夺命书生在不甘中，倒到地下，露出尖端沾染着鲜红的血的枪杆，眼睛大睁，死不瞑目。本片反映周恩来1938年底至1946年5月在重庆南方局将近9年的战斗生涯。这是周恩来一生中最辉煌的时期之一。周恩来遵照中共中央的指示代表中国共产党同国民党进行国共合作、促蒋抗日的谈判，领导南方局、国统区和南方各省党的工作、军队工作、统战工作及宣传文化教育工作。充分展示了周恩来过人的智慧、炉火纯青的斗争艺术、丰富的个人情感和人格魅力。表现了周恩来在政治斗争中的原则性、坚韧性和灵活性，以及对战友、对青年、对孩子们的关爱和对父母的亲情。同蒋介石谈判是政治上的较量。蒋介石从被迫接受国共合作抗日开始，就坚持国共合并取消共产党、取消解放区和人民军队。周恩来坚持国共合作，团结抗日、反对投降；坚持共产党独立、维护解放区、八路军、新四军生存、发展和进行抗日的权利。经过几年艰苦持久的谈判、斗争，共产党成为中国人民抗日战争的中流砥柱，解放区得到巩固发展并连成片，人民军队从抗战初期的五万人壮大到五十多万人。周恩来和延安党中央、毛泽东紧密联系、配合默契，经常是迭电往返或周恩来回延安汇报。针对蒋介石的《中央提示案》Public int pret (Context context);如今出了这等事情，实在脸上无光。
