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.
临走时，他朝西墙看了一眼，那一面墙都是内嵌式的书架，壁间雕刻着各色花草虫兽、树木人物，繁复异常。
During the establishment of a tcp connection, If the server returns syn and ack messages, The client does not confirm it for some reason. This is because the server needs to retransmit the syn + ack message and wait for the client's confirmation message until the tcp connection timeout. This state of waiting for the client to confirm the connection is usually called a half-open connection. The half-open connection will be kept in the connection table of the server until the connection is disconnected.
