Method and system for detecting interface status and processing interface fault according to interface status

Abstract

The invention provides a method for detecting interface status and processing interface fault according to the interface status. The method includes: when starting communication terminal equipment, creating a virtual file system; predefining a signal processing function and a socket function; acquiring name of a network card and a first interface status return value through an input and output control request associated to a network socket, and acquiring network card information from the virtual file system; judging whether the acquired network card information is matched with the network card or not; if yes, judging whether a first interface is under a connection status or not according to the first interface status return value, and if not, giving an alarm to prompt a user; if yes, detecting whether the first interface and a second interface are located on a same network segment or not; if the two interfaces are located on the same network segment, invoking the signal processing function, and reconfiguring network parameters. By the method, the problem that client sides cannot access to the internet under the condition that a WAN (wide area network) interface and an LAN (local area network) interface of router equipment are located on the same network segment is solved, and utilization rate of system resources is increased.

Description

technical field [0001] The invention belongs to the technical field of computer communication equipment, and in particular relates to a method and a system for detecting interface states and processing interface faults according to the interface states. Background technique [0002] A router is a computer network device that provides two important mechanisms of routing and forwarding, and is a device that connects to a local area network and a wide area network. The LAN interface (LAN interface) is mainly used to connect the router to the LAN. The interface connecting the router to the WAN is called the WAN interface (WAN interface). A router is a bridge connecting a LAN to a WAN, between WANs, and between LANs. The router is connected to the interface through a network cable, and only by configuring or obtaining the corresponding network address can it be connected to the Internet normally. The network device is connected to the uplink device through the WAN interface. I...

Problems solved by technology

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a method and system for detecting the interface state and processing the interface failure according to the interface state, which is used to solve the problem of the communication terminal equipment in the prior art, especially the router when connecting to the LAN. In the case of the WAN interface and the WAN interface, it is impossible to automatically detect the connection status of the WAN interface and know the network failure as soon as possible, and the communication terminal equipment cannot solve the problem that the client cannot connect to the Internet when the LAN interface and the WAN interface are in the same network segment
