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).皇帝在后宫夜夜笙歌，沈湎於酒池肉林中，白莲教主顾允成一心推翻昏君，派出得力弟子钱一本和女儿顾芙蓉行刺狗皇帝。德高望重的老支书被儿子顶下来后，去城里生活了一段时间长了见识，回到家乡搞旅游餐饮业，到街上利用民间艺术吸引观众，在50岁时实现带领乡亲们富起来的夙愿。本片围绕时尚品牌古琦（Gucci）的第三代接班人毛里奇奥·古琦（Maurizio Gucci）的故事展开，毛里奇奥是古琦创建人古琦欧·古琦（Guccio Gucci）的孙子，1995年被一个西西里岛的年轻人枪杀于米兰办公室的楼梯上，他的妻子Patrizia Gucci因策划杀夫一案而被判入狱29年。　　求问：这出始于谎言的“塑料情侣”大剧，她究竟要不要假戏真做？不如带我们去了，你也不用抗旨了，我们也遂心了。
