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.Manaka looked like this:Effect Category这不折腾人嘛。新时代好男人潘向东（陈赫 饰）娶到了校花罗洁（王鸥 饰），小俩口婚后的日子虽拮据却很幸福。然而这天，罗洁突然提出离婚，深爱妻子的潘向东措手不及，却拗不过罗洁，迫不得已离了婚。离婚后的潘向东，深受打击，生活跌入谷底。这时，他遇到了同病相怜的男人蔡郝贵。在蔡郝贵影响下，潘向东买了一张彩票。孰料，这张小小的彩票，彻底颠覆了他的生活。潘向东摇身一变，成了千万富翁。恰逢此时，罗洁突然归来。罗洁告诉他，离婚是因她误以为患了绝症，怕连累丈夫，不得不选择离婚。如今，她发现是误诊，喜极而泣的她，立即要复婚。潘向东却误以为前妻回来是因他的钱财，拒绝复婚。从绝境逃出来的罗洁，恢复了生活所有的自信与热忱，她发誓要把自己亲手送走的幸福，重新追回来。于是，她费尽周折地住进了前夫的对门。从此，踏上一条倒追前夫，令人捧腹大笑又温暖备至的复婚之路。该剧以上世纪二、三十年代的苏州为背景，以一个传统的香料世家为依托，诉说了一个“灰姑娘”从嫁入豪门到豪门立足的辛酸悲歌。剧中家族关系交织，正反双方明确，善恶分明。其中贯穿人物跌宕起伏的命运，是对传统“灰姑娘”故事的完美演绎。 一位心地善良，秉性坚持的“灰姑娘”，一个经历风雨飘摇的传统商界世家，一段家族内部争斗的曲折历程，一曲歌颂人性善美的赞歌。构成了整个剧的风格和基调。该剧以一个瑰丽的江南园林为依托，创造出一个仅限于剧中的世外庭院。该剧同时杂糅进民国时代的一切东方与西方，传统与现代的元素。以情节剧的方式创作情感剧，突出矛又戏笑道：你这么像我张家人，说不定真跟我张家有渊源。
