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.郑老太太虽然心里还不顺，也被他逗得眼带笑意，知道他最是灵透的，菊花办事也稳妥，因此便不再言语。但是现在如果他死的话，就没有人能够牵制项羽，所以还有很长一段时间需要刘邦的存在。周行文买了一瓶白酒，一个人坐在街头喝着，这时天空忽的打雷下雨。五百年前的大明京城，一家小医馆里生活着一群乐呵的年轻人。一天，医馆馆主离奇失踪，徒弟朱一品随后收到一个卷轴，无意中打开后，天生的神速记忆让他快速阅读并记下了卷轴的内容，之后就晕厥过去，卷轴也随之烧成灰烬。东厂西厂得知后，派麾下高手杨宇轩与柳若馨前来医馆卧底查探卷轴里的秘密，阴差阳错，他们和朱一品卷入一个个离奇案件。新人入局，也打破了医馆往日的平静。柳若馨年轻貌美，杨宇轩高大英俊，朱一品、赵布...如此爽快的情节，童岳感觉恐怕只有天启才能写出来。
