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.空军903师是一支有着光荣传统的优秀部队，副师长印双虎（李光洁 饰）飞行技术高超，是师长的有力竞争人选。在与参谋长岳双龙（王斑 饰）的演练对抗中印双虎胜出，但其僚机却遭遇飞鸟撞击事故，在鸟类学家柳琪（黄奕 饰）帮助下，印双虎未受责罚。不久后，岳天龙担任903师师长，印双虎颇为不甘，柳琪亦调入常务连成为空军一份子。印双虎与岳天龙的矛盾因训练理念不同而爆发，熟稔国外空军训练的岳双龙强调实战，而印双虎更尊重前人的摸索经验，二人争执不下，岳天龙随即提出分组对抗，印双虎与岳天龙两位优秀空军指战员展开了一系列伴随着惺惺相惜的对抗与合作……汪直的情感无非两点——一是愧疚，二是失望。4.
