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).As Charlie Munger said: I keep seeing some people get better in life. They are not the smartest or even the most diligent, but they are learning machines. They sleep a little smarter every night than that morning.长篇电视连续剧《我本英雄》秉承了周氏剧传统的大开大合、厚重凝炼的故事风格。故事人物延续了上一部电视剧《我主沉浮》的主要脉络，表现了我国改革开放进程中的深层次矛盾，惊心动魄又感人至深地讲述了一个大中国的英雄故事，在当代剧中第一次揭示了科学发展观的重大命题。剧作成功地塑造了赵安邦、裴一弘、石亚南、方正刚等一大批优秀共产党人形象。文山市委书记石亚南，市长方正刚为尽快摘掉经济欠发达的帽子，构筑了钢铁立市的宏伟目标。在为实现七百万吨钢铁产量而呕心沥血的过程中，他们没有接受省长赵安邦的严厉警告，追求GDP，追求高速度，做了许多违规违纪并违背经济规律的事情。当国家进行宏观调控时，文山钢铁基地陷入困境，经济全面停顿。投资钢铁项目的企业家吴亚洲自杀谢罪。尽管赵安邦、石亚南、方正刚挽救了经济败局，但仍没有改变被查处的命运。关键时刻，石亚南挺身而出，主动请辞，体现了共产党人高贵的人格力量。
