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).

In the course of practice, Teacher Sun Yimin said more than once, "I hope our practice can make more students pay attention to employment and entrepreneurship. "There are priorities in learning and specializing in technical fields". Everyone's value is often reflected in different aspects. We should find our own way and direction instead of blindly following the principle of postgraduate entrance examination. Industry is also the top priority of the country's development. Investment in industry can also achieve a career! " As a retired old teacher, Mr. Sun, who was supposed to live a leisurely life at home, was still able to stay far away from the "Jianghu", worried about his "monarch" and still chose to devote himself to student work. Such a mind is really admirable!
