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).勉强还能维持一下，但是魔道众人那就惨了。二十一世纪初，亚洲年轻富商何凡接受访问，讲述自己白手起家的艰苦发家史，从而引出了何凡父母客死异乡的悲惨身世；二十世纪70年代末，香港商人何俊携妻张丽及一对十岁的孪生兄弟奔赴新加坡创业。新加坡富商钟基之女钟睛垂涎于何俊的俊朗外貌却遭到拒绝，于是使用恶毒手段将何俊夫妇迫害致死。何氏兄弟被送回中国内地，他们立志要出人头地，为父母报仇雪恨。90年代初，随着改革浪潮的蓬勃涌动，兄弟俩决定抓住机遇有所作为，早日与仇家一决高低。就在何氏兄弟奋发图强之时，几个性格迥异的女人闯进了他们的生活，引发了一段段情感纠葛。彩儿回禀道：已经开始了。征战三界，凌驾于仙神之上，让巫和人主宰三界。Panshan Park is located on the north side of Jinpan Section of Jiangbin North Road in the urban area, with a total area of about 70 mu.
