When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.

Zero inventory is one of the cores of JIT production mode. Only by ensuring "zero defects" can the goal of zero defects and zero inventory pursued by JIT production be realized. JIT production mode requires zero defects and zero inventory in all links of supply, production and marketing, which requires all links of production and operation to coordinate with each other, run smoothly and ensure high quality. Due to the close connection between various activities in the production process, the defects in a certain link will cause chaos in production, cause chain reactions, and cause the collapse of the timely production system, with incalculable losses. Therefore, when an enterprise should implement JIT production, it should mobilize all employees to actively participate. From the selection of suppliers to the design of products, the determination of production processes, and the production and sales of products, quality management should be strengthened in all stages. Through the self-control of relevant personnel, defects should be eliminated in real time, thus realizing zero defects in the production and operation process.
