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.　　Abigail Spencer饰演Lucy Preston，一个聪明﹑机警﹑热情的历史学教授，被政府带走并参加一项穿越时空的绝密任务。Matt Lanter饰演Wyatt Logan，一同坐上原型时间机器，看着并不靠谱。Malcolm Barrett饰演Rufus，第三名穿越时空的人，是个聪明的...　　讲汽车吴臣疑惑道：父王，怎么说？吴芮淡淡道：你还没看出来吗？越国出兵占领了彭蠡泽以西的土地，那里本是你姐夫的封地，现在已经名正言顺地属于越国了。　　造型指导：杨威|王昊郦食其续道：不止如此，之前被我们追捕，下落不明的章邯也在江东，现在任职越国上将军，是越王麾下大将。陆家嘴投行女，虹口货代销售男，静安优渥女，杨浦土老外、跟着上海的路牌，学习最快的都市识人术。在大城市中习以为常的“一派和谐”，在每个人的内心独白中撕裂开真相，每个看似不可理喻的行为背后都有一套行之有效的价值观。这样的老司机话题剧在一众偶像剧、玄幻剧当中显得十分特别，给网生剧赋予更多深刻的生活意义，全方位展现上海这座大都市的真实与残酷，描绘一副都市人追逐欲望群像。
