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.童年贫瘠的时光，姜生和凉生相依相偎，尽管是没有血缘的兄妹，仍对彼此不离不弃，物质虽然匮乏，精神却无比充实。他们双双考入理想大学后一场车祸，凉生失踪，由此揭开了凉生的身世之谜。姜生苦心寻找凉生，程天佑陪伴左右，深深爱上了这个平凡而不平常的女孩。凉生回归，成为了程天佑的表弟，错综复杂的家族关系，让三人的生活再也无法平静。噩耗降临，凉生得了骨髓血癌，姜生为挽救凉生的生命，放弃出国留学的机会，割舍对程天佑的爱，回到凉生身边。Module usually refers to the code organization mechanism provided by programming language, which can be used to disassemble programs into independent and universal code units.
