In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).

The main difference between the proxy mode and the appearance mode is that the proxy object cannot directly access the object, but can only be accessed by the proxy object, while the appearance object provides a simplified access call interface for each subsystem, while the adapter mode does not need to fabricate a proxy, so as to reuse the original interface. The appearance mode defines a new interface, while the adapter reuses an existing interface.

"Because the artillery suddenly 'dumb fire', Later, it was said that it was the same as position 169, because the ammunition consumption was too large and too many shots would be supplied for a while. It was not wrong to say so, because at the peak of the attack, the number of the two strange things released by the Vietnamese army below was too large to count. Have you ever seen ants crossing the river? That's what it feels like, If they are piled together, The density is almost a "ball", So in this case, The firepower of the artillery group is especially strong, Ammunition consumption far exceeded previous expectations, After all, no one expected to meet such a thing at that time, We didn't know how to describe it when we sent back messages on walkie-talkies at the front line. Anyway, it just said that the number of enemies was very large. Hit them hard, It was also the most intensive shelling I have ever seen. In the blink of an eye, It is normal to drop 4-6 shells on an area of about one square meter or even at the same time. The entire position 142 trembled under the shelling, At last, I felt that the ground under my feet would be overturned. Now think about it. If it weren't for the artillery comrades' hard support for us, the dozen or so people and the guys in our hands at that time could not withstand the attack of so many strange things. If they were called to rush up, they would have to tear us up and chew us up.
