Real-time system network data capture and analysis method, system and device and storage medium

Abstract

The invention discloses a real-time system network data capture and analysis method, system and device and a storage medium. According to the method, whether the network data message is captured or not is judged firstly, then whether the protocol type needed by the message is judged, then whether fault injection needs to be achieved or not is judged, and finally whether the network data is the data message transmitted into the standard protocol stack or not is judged, so that the network communication state can be rapidly, accurately and reliably monitored in real time. According to the invention, the network communication fault rapid positioning capability is enhanced, the product troubleshooting cost is reduced, and the method has definite technical and economic benefits. According to the method, the messages can be analyzed in real time from the complex and massive-dimension network data messages of a complex network topology structure, and the network messages can be classified andfiltered in real time on the basis of ensuring the processing efficiency. The method can be used for monitoring data in real time, simulating network data loss and realizing fault injection, and hasfunction expansibility.

Description

technical field [0001] The invention belongs to the field of embedded real-time system network communication data capture analysis and simulation fault injection, and in particular relates to a real-time system network data capture and analysis method, system, device and storage medium. Background technique [0002] In embedded real-time systems, there are various reasons for network failures, such as network card chip failures, network driver vulnerabilities, imperfect network protocol stacks, and incorrect application programs, etc., which may lead to failures. Common troubleshooting methods include: upper-layer application communication testing method, third-party monitoring method, bottom-level detection method, and layer-by-layer inspection method. The upper-layer application test method runs an independent and simple network test program on the upper-layer application layer of the target machine to detect whether the network communication link of the target machine is ...
