Compared with SYN cache method, SYN? Cookies technology does not need to allocate space at all when receiving a SYN. Because the most basic data that make up the connection state are encoded and compressed into the sequence number bits of SYN-ACK. For a legitimate connection, the server will receive an ACK message segment with a serial number (actually the serial number has been added by 1), then the basic TCB data will be regenerated, and a complete TCB will confirm that the data will be safely instantiated through decompression. This decompression can be successful even under severe attacks, because there is no storage load at all on the host side, only the load that calculates the encoded data into the ACK sequence number. The disadvantage is that not all TCB data can be added to the 32-bit sequence number segment, so some TCP options required for high performance cannot be encoded. Another problem is that such SYN-ACK message segments will not be forwarded (because forwarding requires complete state data).本剧描绘了优柔寡断、不起眼但温柔的大学生·木下和也，因为被交往一个月的女友甩了，赌气登入出租女友，与水原千鹤约会的开始租赁的恋爱故事。致力于制作最接地气学生搞笑视频节目，代表作品《学校里的疯子》　　Ronnie（Ntare Guma Mbaho Mwine饰），前军人的他被芝加哥南区的生活拖垮，他平常经常与邻里的朋友打混，不然就是照顾自己祖母。不过某天她的前女友（Ronnie视她儿子如己出）驱使他为一宗谋杀案报仇时，Ronnie为了赢回前女友的心将会走上一条错误的路。这可是从未有过的事，也是有缘故的：环视帐中，全是长胡子的家伙，有些还脸皮起皱。倭寇猖獗。
