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 outer surface is plated with oxygen-free copper, and the raw materials of the core wire are brass, bronze and miscellaneous copper. Because the raw materials of copper inside and outside are different, it is called copper clad copper. The quotation is moderate, and the quotation for miscellaneous copper is usually only half or lower than that for oxygen-free copper. The produced wire is attributed to non-standard wire, and its anti-twisting and anti-oxidation functions are better than those of copper-clad aluminum. Suitable for induction and wiring engineering with low accounting, it can lay hidden lines in the wall. However, due to the influence of raw materials, the resistance is relatively large, with a 100-meter resistance of 25-35 ohms or even more, and the signal attenuation is very large. It is not so-called all-copper. We pay attention to the distinction.
