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.本来以为到了萧县，可以暂时站稳脚跟，可是现在看来，项羽根本没有给自己这个机会。张大栓、张槐和板栗则去至前院，往刘管家、王忠管事家、严师傅朱师傅家中，以及护院住处等，各处看望。迪亚兹一家有七个孩子，排行中间的哈莉无疑是这个家中最没有存在感的孩子。但事实果真如此吗？她忙着照顾一大家子人的饮食起居，经常用自己的小发明解决大家庭的难题。她就像万能胶，让九口之家紧紧团结在一起。看看这个小女生是怎么撑起半边天的吧！讲述了农民工进城务工,其子女来城市接受教育,与城市里的孩子相互碰撞、理解、沟通,最终成为好朋友的动人故事。情景喜剧《家有儿女》是以一个重组家庭作为故事平台,演绎出不同的血缘、不同的年龄、不同的出生地、不同的性格的三个孩子和父母之间的故事,蕴藏着诸多的喜剧因素和戏剧冲突。文革结束，柳碧云和江天怀这对再婚夫妻分离十年先后回城，带着各自的儿女一起生活，面临着事业的种种挑战和家庭矛盾的困扰。继女江梅和奶奶联手制造了很多家庭矛盾，柳碧云从来没有放在心上，一直感化着江梅；江林和李冰虽然是非亲生兄弟，但每当彼此遇到困难时，都能出手相助，让江天怀柳碧云很是欣慰；女儿江雪因为感情问题受到伤害，在家人们的呵护下度过难关，恢复高考后，通过努力考上大学，用知识改变命运；继子江森早早在农村成家，媳妇王改凤在生活习惯上与柳碧云有着分歧，柳碧云用她的方式慢慢影响着他们。江天怀深爱着柳碧云，帮助她一起解决家里的各种矛盾，他们用爱感化着家里的每一个人，并引导儿女们健康、快乐地成长。步入老年，柳碧云江天怀回首往事，一生无悔，儿女们更是庆幸有他们这样的爸妈。
