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.

10-15% of aquatic plants and hidden objects are planted shallowly at the edge of the pond to create an environment for lobsters to inhabit and shell and reduce mutual killing. The influence of water quality on lobster yield cannot be ignored. During the breeding process, the PH value of the pool water is kept between 7.5 and 8.5, and the transparency is 30-40cm. Fresh water should be added frequently, quicklime solution should be splashed regularly, water quality should be adjusted, and diseases and shelling failure should be prevented. 2. Feed feed reasonably. Lobsters will kill each other when hungry and under-fed, so the feeding amount must be sufficient. Lobster feed is animal and plant feed. Plant feeds are wheat, aquatic plants, rapeseed cakes, etc. Animal feeds are miscellaneous fish, miscellaneous meat, livestock viscera, etc. At ordinary times, the feeding time, feeding amount and feeding method are determined according to the habit of lobsters falling in the day and coming out at night and the density of lobsters in the pond. 3. Scientific fishing. Young shrimps can grow to commercial specifications in 60-90 days under the condition of suitable temperature and sufficient feed. The seedlings will be released in March and will be caught in rotation around June, selling large ones and keeping small ones.
