In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).陈佩斯系列喜剧短剧1927年，滇军策应广东革命政府北伐号召征讨军阀唐继尧，双方激战昆明城外。马夫兵杨志华凭借天赋一炮命中杜清时的战地指挥所，虽然战败被俘，却因神炮技艺死里逃生。杨志华阴差阳错考入讲武堂，和高材生杜清明冲突频发。但其得到教官枝野胜男的严酷训练，成为最没文化的神炮手。抗日战争爆发，杨志华加入八路军部队奔赴华北战场，意外与杜清明重逢。一个八路军营长，一个国民党教官，二人摒弃前嫌，携手抗敌，与枝野胜男多次较量，师生决战战场。枝野胜男出尽奇招，组建特种部队，杨志华的炮兵营多次陷入危机。历经挫折考验，杨志华和杜清明反败为胜，在关键战役打败枝野胜男而名声大噪。抗战胜利，国共分裂，杨志华和杜清明又在济南战役兵戎相见。这是一部女性题材的电视剧，通过女性的视角，探讨在现实生活中女性复杂的情感和伦理道德问题。每一集一个独立的故事。每集故事都反映女性的个人情感上的不幸遭遇和千奇百怪的婚恋现象。《放爱一条生路》表现了一个男人疯狂地爱上一个女人，女人承受不了他偏执的爱而选择了逃离；《继母》反映了作为继母如何赢得前妻子女的信任，子女们把她当作亲身母亲对待而取代了亲生母亲的位置；《你要的爱》表现了一个女人如何爱上了见义勇为的残疾青年的故事。本剧集旨在引导女性自尊自爱自强。The responsibility chain is composed of a number of different objects.
