Abstract

This invention is a divisional application of 201710679503. X. The embodiment of the invention provides a method and apparatus for detecting a parallel redundant network fault. The method comprises the following steps: calculating the numbers of management frame messages received by a first port and a second port, wherein the first port and the second port are ports on a first device in a parallelredundant network, and the first port and the second port are respectively connected with a second device through different networks in the parallel redundant network; when the number of management frame messages received by the first port and / or the number of management frame messages received by the second port meets a first preset condition within a preset time, or, the relationship between the number of management frame messages received by the first port and the number of management frame messages received by the second port meets a second preset condition, determining that the network is abnormal. By adoption of the technical scheme, whether the network for transmitting the messages is in a normal state can be obtained in real time so as to determine the accuracy of the transmittedmessages.

Description

[0001] This application is a divisional application, the application number of the original application is 201710679503.X, the application date is August 10, 2017, and the title of the invention is "a method and device for detecting duplicate messages and faults in a parallel redundant network". technical field [0002] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method and device for detecting faults in a parallel redundant network. Background technique [0003] With the advancement of industrial technology, in order to further improve the reliability of industrial Ethernet, the technology of packet redundancy backup appears. Among them, taking the IEC62439-3 protocol as an example, it stipulates that at the sending end, each message to be sent is copied to obtain two identical messages, and these two messages are sent through different ports. When receiving the two messages, different ports of the receiv...
