Problems solved by technology

[0005] Since the source node will send a Path message every once in a while (such as 5 seconds), and after sending the Path message, it needs to wait for a preset time (such as 1 second), if no response message is received within the preset time The TE tunnel will be dismantled only after the document is specified. The dismantling time of the TE tunnel is relatively long, and resources will not be released during this period.

Abstract

The present disclosure provides a TE tunnel fault detection method and device, the method comprising: determining a first type of TE tunnel passing through a first detection node and a second detection node; generating a detection message for the first type of TE tunnel, and The detection message is sent through the first type of TE tunnel, and the target node of the detection message is the second detection node; Detecting a response message of the message, and determining that the first type of TE tunnel is not faulty; otherwise, determining that the first type of TE tunnel is faulty. Through the technical solution of the present disclosure, it is possible to quickly detect whether a TE tunnel fails, and when the TE tunnel fails, the TE tunnel is removed in time, and the time for removing the TE tunnel is relatively short. It can accurately detect whether the TE tunnel is faulty, and the detection result is accurate and effective.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for detecting a fault in a TE tunnel. Background technique [0002] Network congestion is the main problem affecting the performance of backbone networks, and the cause of network congestion may be caused by unbalanced network resource loads. TE (Traffic Engineering, Traffic Engineering) is a method that can be used to solve the congestion problem caused by unbalanced network resource loads. Technology. Among them, in a complex network environment, TE technology can be used to control the data transmission path and dynamically adjust the data transmission path, thereby optimizing the use of network resources and avoiding congestion problems caused by unbalanced network resource loads. [0003] In order to control the data transmission path, a TE tunnel can be created between the source node and the destination node, such as figure 1 As shown, ...
