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).上官雪儿本是假扮武天睿的女朋友，没想到却遭到他哥哥武天祥的无情报复，因为武天祥误认为是上官雪儿害死了弟弟武天睿。上官雪儿为此流离失所，甚至丢掉了工作，被无尽羞辱。更令上官雪儿意外的是，对自己宛如暴君的武天祥竟是自己大学时暗恋的学长，可是武天祥却根本不记得她这个学妹。上官雪儿在品尝暗恋的苦涩中，并没有向武天祥低头，坚定自己的清白，抵抗着武天祥的虐袭。最终，上官雪儿忍受不住武天祥无情的报复，谎称自己怀了武天睿的...Introduction: This action is usually used when congratulating others.What qualifications and requirements does a male kindergarten teacher need?该剧讲述了萧清、书澈、缪莹、宁鸣、成然和绿卡等人因为家庭、理想、爱情等种种原因相聚美国，成为藤校精英后，从象牙塔走向社会，一步步完成蜕变的故事。直到云青山到来之后，道出自己是真心实意归附越王的。该剧讲述的是1939年的上海，王家和洪家的年轻人，经历了种种的风雨考验，踏上了不同的人生道路的故事。
