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).　　学成出师的王兆杰（钱小豪 饰）、吴立（程琢 饰演）及一众师弟，踏入影视圈做武术替身演员。因兆杰功夫过硬且十分敬业，得到女星陈诗琦（胡然饰）青睐担任其替身演员，却得罪同组富二代男演员葛政（张明明 饰）。葛政对王兆杰各种使坏，甚至让师弟重伤入院。心有所愧的兆杰人生陷入黑暗，燃烧的武术梦也逐渐暗淡……2017年5月15日爱奇艺独播。 美国留学进修音乐的江上饮，由于在金三角惹到地方黑帮，只好到一家泰国唐人街技校当教导主任打工作为赔偿。这所技校只有四个专业，一个是一群泰拳高手组成的泰式按摩专业，一个以杀马特为美学最高标准的美容美发专业，一个是男女不分的模特礼仪专业，还有就是放弃了所有美食套路专精各种咖喱的烹饪专业。虽然四大专业看起来有些四六不靠，但是为了生存，江上饮只好放手一搏来到学校，结果面试中江上饮和校长产生了一个不大不小的误会，使得江上饮从一个“海归音乐教师”变成了“遣返黑帮教父”。于是如何在一群叛逆少年和怪咖教师中生存下去就成了江上饮最大的考验。而且最让江上饮头疼的除了日常工作之外，他还有一个既不靠谱又无靠山的“废柴盟友”史飞楼，史飞楼因暗恋着校长的女儿---sun老师。史飞楼本职工作是一名洗车工，是一个内心善良，但是行事猥琐的怪异少年。于是这样两个不着调的二人组出现在了这个充满泰式风情的次元技校当中，必然会引发了一系列令人啼笑皆非的故事。4.
