The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.

Stocks have double-click and double-kill, as do investors themselves. Many unknown people rely on the classic record of a certain year or a certain year, and their performance has soared and their popularity has soared. This is actually a double-click process. This is undoubtedly a lucky good thing in itself, but if you are praised for kidnapping, you will only cheat yourself in the end, and then bitter double killings are almost inevitable. There are not many fresh passages in the investment plot, and the main characters are changed frequently. An iron law in the business world is that there must be high barriers to excess returns. This bumpy truth will not change because we invest in stocks or because we choose different investment styles.
But then again, It is not entirely true to say that the fire cut-off at position 142 is exactly the same as that at position 169. Because in addition to the large consumption of ammunition, There is also a major reason: It was at that time that some comrades of the reconnaissance troops found out that the Vietnamese army had failed to sneak attack. Pull a large number of large caliber artillery prepared in advance out of the woods, Prepare to support the infantry that stormed various positions.

Later, I also saw in a military magazine that when the artillery battle was the most intense, some artillery comrades who pulled the bolt swollen their arms. It is conceivable how fierce the fight was. " Li Haixin said.
