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.　　被提拔到镇里当干部的长贵渐渐瞧不起大脚，在镇上结识了一个美丽的理发师，并对她暗生情愫。不过长贵最后却被单位开除，重新回到村里，面临着对人生的重新思考……It is a sequence of events rather than a single event that is studied.板栗望着蜷缩在凳子上的少女，很想把她弄上床来，自己去睡凳子，但想想那未知的军队生活，还是忍住了。本剧通过讲述主人公黄自立的奋斗史，诠释了爱与被爱、幸福与奋斗的人生真谛。 十年苦读奋斗，努力工作的黄自立，因一连串的重击导致人生跌落谷底。然而他并未屈服于命运的安排，在艰难逆境中始终坚持拼搏向上。因为误会，他与女警察方言相遇，经过相处后，方言为了不让黄自立分心，下班后还会主动照顾黄自立的家人。在交往过程中，两个人产生了强烈的好感，黄自立预感到幸福终于来到了，最终赢得了美好的人生。《幸福还会来敲门》是弘扬主旋律，传递正能量的电视剧，诠释了“人民对美好生活的向往”的主题，全剧以男女主角的故事为主线，展现出“幸福都是奋斗出来的”的核心价值观，展现普通小人物奋斗故事的正能量品质剧，激励民众凭借自我努力奋斗，追求幸福的故事。《模仿游戏》根据Andrew Hodges所写的传记《艾伦·图灵》（Alan Turing: The Enigma）改编。艾伦·图灵是英国数学家、逻辑学家，二战中曾协助军方破解德国的著名密码系统Enigma，对盟军取得了二战的胜利有一定的帮助。图灵对于人工智能的发展有诸多贡献，著名的图灵机模型为现代计算机的逻辑工作方式奠定了基础。
