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).

Tong, no unit or individual is allowed to occupy the fire exits to build houses, pile things and set up stalls. The existing flammable building intensive areas in cities and towns should be gradually transformed in combination with the overall planning of cities and towns, and contiguous transformation can be carried out if conditions permit. Fire lanes are generally not allowed to park other vehicles, and residents should be discouraged from building illegal buildings and piling up articles. 3. Requirements for setting up fire lanes in factories, warehouses, storage yards, storage tank areas and large public buildings According to the reflection of each fire fighting squadron in fire fighting practice, When a fire occurs in a large area of factories, warehouses, storage yards and storage tank areas, the fire burns very fast, the fire is fierce, and the fire fighting lasts for a long time. If there is no fire ring lane and flat open space, it will inevitably cause fire vehicles to be unable to enter or leave, which will inevitably cause blockage and make it difficult for fire engines to approach the fire site. Therefore, fire lanes should be set up in factories and warehouses. When a Class a, Class B and Class C factory building occupies an area of more than 3000 square meters or a Class B and Class C warehouse occupies an area of more than 1500 square meters, a flat open space with a width of not less than 6m for fire engines to pass through can be set up along its two long sides. Open yard area for flammable and combustible materials, Liquefied gas storage tank area, For Class a, Class B and Class C liquid storage tank areas, there shall be large public buildings such as fire lanes or flat gymnasiums with a width of not less than 6m and a space of more than 3,000 seats, halls with more than 2,000 seats and exhibition halls with an area of more than 3,000 square meters that can be passed through by fire engines. Because of the large volume, large floor area and large and dense personnel, in order to cause fire, there shall be large public buildings such as the gymnasiums with a flat space of more than 3,000 seats, halls with more than 2,000 seats and exhibition halls with an area of more than 3,000 square meters.
