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.张槐见儿子全无往日嬉笑模样，也慎重起来，对他点点头道：找个日子，爹跟你大舅一块跟秦大夫提这事。老一代唢呐艺人焦三爷是个外冷内热的老人，看起来严肃古板，其实心怀热血。影片表现了在社会变革、民心浮躁的年代里，新老两代唢呐艺人为了信念的坚守所产生的真挚的师徒情、父子情、兄弟情。Manaka is now connected to the following 9 subway cards across Japan, all of which can be used throughout Japan.周菡就傻了：要打仗了？那怎么办？林聪纳闷地问道：什么怎么办，打仗有你什么事？周菡道：我不放心呢。我的杀意恋爱了番外 故事讲述正篇没有描写的柊（中川大志）、美月（新木优子）、流星（铃木伸之）等登场人物过去的连锁故事。公元前72年，古罗马一段悲壮的奴隶抗争故事交织出爱恨情仇……古罗马
