In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.

Looking back on this social practice, I have learned a lot, learned a lot of social experience from everyone I contact, and improved my potential, which I cannot learn in school. It takes long-term practice to be good at communicating with others in society. In the past, I did not have the opportunity to work, which made me unable to adapt to changes when talking with others and made the conversation silent. This was very embarrassing. People will integrate into the social group in the society, and people will work together to make the process of doing things more harmonious and get twice the result with half the effort. You should listen to the opinions given to you by others and understand them patiently and modestly. Be confident in your work. Confidence is not a numb boast, but an affirmation of one's potential. Lack of social experience, lack of academic qualifications and other reasons will make self-confidence lack. In fact, anyone who is born with confidence can overcome psychological barriers and everything will become easy to solve. The accumulation of knowledge is also very important. Knowledge is like human blood. Without blood, one's body will weaken, and without knowledge, one's mind will dry up. The brewing industry contacted this time is very strange to me. If I want to do a good job, I must understand this knowledge and have in-depth understanding of all aspects so as to better apply it to my work.
