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).在《江南Style》的MV中，大部分的外景都取自于位于江南区的桑拿房、马厩、游艇、海滩、旅游巴士等，延续了鸟叔的幽默风格，舞蹈也颇有亮点。　努尔特之王计划窃取夜间动物园的颜色，使动物处于极大的危险之中！而夜间动物园管理员威尔和他的朋友能拯救夜晚动物园吗？
