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.
Well, it's this simple and crude.

1945年4月23日中共七大开幕，毛泽东所做的的七大政治报告《论联合政府》引起了全国进步民主人士的热烈反响。与此同时国民党也召开了六中全会，因为蒋介石的独裁，使国民党内很多人不满。而共产党和平、民主、团结的主张，很得人心。无奈之下，蒋介石决定召开国民大会，颁布宪法，想通过国民大会的形式，使国民党获得执政权，并借此拉拢其他一些社会党派。双方的斗智斗勇拉开序幕。
