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.Origin of jerseys: Turkey在19世纪的比利时法兰德斯。一天，一位修女造访了安特卫普镇的大教堂。这位修女仰望著鲁宾斯《圣母昇天》画时，记忆一下子回到了20年前……The case came to light in December 1998 when fishermen of a fishing boat accidentally recovered a naked, chained and mutilated body near the waters of South China.Overlay1993年的上海，有一群特殊的人群——酒店领班，每日衣着光鲜，出入高端酒店，结识不少社会名流，小费收入颇丰。24岁的路途（阮经天 饰）是上海最年轻的酒店领班，更被美籍华人米先生赏识，邀请其成为在纽约建成的“曼哈顿上海大酒店”上海负责人。许多人怀着不同的欲望来接近路途，其中也包括阿鹃（杜鹃 饰）。阿鹃最终如愿以偿地到达纽约，却愕然地发现一切超乎了她的想象。路途在上海得知真相后，决定去纽约找回阿鹃。纽约梦是否只是浮生一梦？梦碎之后路途和阿鹃又该何去何从？《典当商》改编自Edward Lewis Wallant同名小说，主人公是一名犹太人典当商，从纳粹集中营逃出后在纽约哈莱姆经营当铺时维持生计，男主角罗德·斯泰格尔由此获得了当年奥斯卡影帝的提名。
