Background
Network interrupt refers to that when CPU normally runs program, CPU interrupts running program due to internal and external event or event prearranged by program, and goes to program for internal/external event or service for prearranged event, after service is completed, returns to executing program for temporary interrupt of running wave.
Network fault diagnosis should achieve three objectives: determining a fault point of the network and recovering the normal operation of the network; finding out the poor part in the network planning and configuration, improving and optimizing the performance of the network; and observing the running condition of the network and predicting the communication quality of the network in time. Network fault diagnosis is based on knowledge of network principles, network configuration and network operation. Based on the fault phenomenon, the network diagnosis tool is used as a means to acquire diagnosis information, determine network fault points, find the root of the problem, remove the fault and restore the normal operation of the network. Network failures typically have several possibilities: the problem of failure of the interconnection of physical devices in the physical layer or the problem of hardware and circuits themselves; interface configuration problems for network devices of the data link layer; network layer network protocol configuration or operation errors; device performance or communication congestion issues at the transport layer; the upper three layers are cisco or web application errors. The process of diagnosing network failures should proceed upward from the physical layer along the OSI seven layer model. The physical layer is checked first, then the data link layer is checked, and so on, trying to determine the failure point of the communication failure until the system communication is normal.

Establishing and re-plugging connection network hardware: the phenomenon caused by the quality problem of the hardware can be solved by replacing or reconnecting, and if the physical reason is generally better solved, the problem can be solved by only pulling and plugging a network cable or replacing a transistor head, enabling a router to turn off a power supply again, and the like.
