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.

In addition, they apply different stages of design, and the appearance mode is used in the early stage of design, because the system needs to rely on appearance in the early stage, while the adapter is applied after the design is completed. When it is found that the designed classes cannot work together, the adapter mode can be adopted. However, in many cases, the use of adapter mode should be considered at the early stage of design, such as involving a large number of third-party application interfaces. Proxy mode is that after the mode is completed, it wants to be provided to other clients in the form of services for calling. At this time, other clients can use proxy mode to access the module.

"Then it was the old method of tracing armour-piercing firebombs that repelled the attacks of the big wasps twice. There was another very special sound from the position.

As for us, through a shortcut of knowledge, just a few days of experiences came to teach us these facts, that multiple species of plants can be used as dyes and that plants carry most of the pigments. However, most of these pigments are fragile and break down easy over time, or once the fabric is washed. Only pigments that well resist oxidation make up valuable dyes.
