When the SYN gateway receives the SYN packet from the client, it directly forwards it to the server. After receiving the SYN/ACK packet from the server, the SYN gateway forwards the packet to the client and sends the ACK confirmation packet to the server in the name of the client. At this time, the server enters the connected state from the semi-connected state. When the client confirms the arrival of the packet, it forwards if there is data, otherwise it discards it. In fact, the server has a connection queue in addition to maintaining the semi-connection queue. If SYN attack occurs, the number of connection queues will increase, but the number of connections that the general server can withstand is much larger than the number of semi-connections, so this method can effectively reduce the attack on the server.

Practical Experience: I got up at 5: 30 on the morning of the 12th, because I had to gather in front of the public health building at 6: 30. This was the earliest time I got up in my college life. It was really a challenge! But I understand that the challenge is just the same as ours. After getting up, washing and tidying up, I finished the breakfast prepared the night before and arrived at the gathering place on time. Although they got up so early, every player was full of passion and did not feel sleepy at all. The teacher arranged us to carry the necessary items such as banners, flags, leaflets, brochures, questionnaires, etc. to the car. We have one more player-the driver. After everything was ready, the driver and master drove to Shexian County. On the bus, the teacher sent everyone a questionnaire to familiarize themselves with the information. At the same time, the teacher divided our 14 students into two groups. As a result, every 2 teachers led 7 students to act separately, which improved the work efficiency. It was already over 1 p.m. when we left at 7 a.m. Since we have not driven to Shexian before, we only asked others about how long it will take us to arrive. We were not familiar with the road and encountered a traffic jam on the road, which made us arrive more than 3 hours later than planned. It's really that the plan can't catch up with the change! I got up early in the morning and ate less. At the moment, everyone's face showed a slightly tired expression, but my eyes were still full of passion. When we arrived, we all had lunch in a restaurant. In order to reduce too much consumption, we also had a simple meal. But we are already very satisfied, after all, this is not the purpose of coming. Coming, we will eat the bitter, do
