As mentioned above, SYN attacks can be prevented by increasing the backlog queue. In addition, reducing timeout time also enables the system to process more SYN requests. We know that the timeout timeout, that is, the half-connection lifetime, is the sum of the timeout times that the system waits for all retransmissions. The larger this value, the longer the half-connection takes up the backlog queue and the fewer SYN requests the system can handle. In order to shorten the timeout time, it can be realized by shortening the retransmission timeout time (usually the first retransmission timeout time) and reducing the number of retransmissions.
We know that TCP protocol opens up a relatively large memory space backlog queue to store semi-connection entries. When SYN requests continue to increase, and this space causes the system to discard SYN connections. SYN cookies technology is designed to enable the server to process new SYN requests even if the semi-connection queue is full.

"Er... I really can't remember the model, it's green, probably so thick." Wang Zeduan could not remember the specific model of the explosive cylinder, Just said the color and gesticulated the approximate size with his hand, Later, I looked up the information and learned that The detonators used at position 142 were all Type 68 detonators, This is also a classic explosive barrel widely used throughout the Sino-Vietnamese border war. This type of explosive cylinder is 60 centimeters long each, As long as there is a need, it can be spliced indefinitely. The charge for each section is 2.2 kg, According to Wang Zeduan's description, At that time, the explosive barrel was made up of three sections. Then the total charge is as high as 6.6 kg, However, the high explosive bomb used in the type 66 152 mm howitzer, The charge is 6 kg, In other words, The charge of these three explosive cylinders is 0.6 kg higher than that of a 152 mm grenade. This is also basically in line with his description that it is more powerful than a shell. In addition, after being inserted into the ground, the two sections of the upper half form a certain blast height from the ground, In this way, the explosive power can be better exerted virtually to cover a wider area, so it is indeed reasonable that an explosive barrel can successfully achieve the tactical purpose of successfully clearing position 142 for the second time (the first clearance is 66-type directional anti-infantry mines and 72-type pressure/tripping anti-infantry mines).
