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).于士鸿率领的西村队在蹴鞠竞赛中夺魁，若云走到士鸿面前表示祝贺。这一幕让铁川看了心里觉得不是滋味。士鸿母亲看到士鸿若云两人拉着手，呵斥成何体统。秉丰胡乱编个借口，若云得以逃脱。铁川为救若云，烧伤胳膊。士鸿和若云互诉衷肠，若云表示看出来士鸿母亲不喜欢自己。将花生放在娘手上，让剥米给他吃。十年前的一个雪夜优姬迷路遭遇恶鬼，幸得贵族吸血鬼玖兰枢所救。十年后，两人在黑主学院再次相遇。对于救过自己性命的枢，优姬心中存着感激与仰慕，枢虽对优姬有好感，但却因种族间的鸿沟刻意远离。而零虽对优姬也有感觉，但坚硬的内心却阻止了他的感情。等待着他们的命运到底是什么......The main contents of this program:《料理情人梦》是台湾一部以美食为主的双生双旦偶像剧，剧中男女主角分别由台湾创作天王吴克羣、人气美女李佳颖、人气可爱女星鬼鬼、新生代演员凤小岳主演，是一部双生双旦（2个男主角&2个女主角）的偶像剧。格雷西的母亲是一名出色的联邦特工，在一次任务中不幸殉职。格雷西（桑德拉•布洛克 Sandra Bullock 饰）长大后继承了母亲的事业，也成为了一名联邦特工。格雷西从小就脾气刚烈、不修边幅，作为“假小子”的她并不受欢迎，只有她的拍档兼好友艾瑞克（本杰明•布拉特 Benjamin Bratt 饰）理解她。
