Problems solved by technology

In the prior art, when multi-links are detected, during the detection process, only the convergence process can be detected, that is, it depends on the data packets returned by the detected end, and cannot actively converge, and the interval between detection packets and the final calculated results Without smoothing, the detection value mutation is relatively large, it cannot adapt to links of different quality, and the application range is small

Embodiment Construction

[0062] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0063] like figure 1 As shown, the embodiment of the present invention proposes an explicit path-based multi-link state detection method, including steps S1-S3:

[0064] S1. Obtain a target link in the multi-link;

[0065] S2. Detect the multi-link state in the first detection mode, and acquire the current detection link;

[0066] S3. Determine whether the current detection link is a target link, and when it is determined that the current detection link is a target link, detect the target link in the second detection mode; the detection time interval of the first detection mode is greater than Probing interval for the second probing mode.

[0067] The working pri...

Abstract

The invention discloses a multi-link state detection method based on an explicit path. The method comprises the following steps: acquiring a target link in multiple links; detecting a multi-link state in a first detection mode to obtain a current detection link; whether the current detection link is a target link or not is judged, and when it is determined that the current detection link is the target link, the target link is detected in a second detection mode, and the detection time interval of the first detection mode is greater than the detection time interval of the second detection mode. On the one hand, the real multi-link quality condition can be reflected to the greatest extent, and on the other hand, the bandwidth is saved as much as possible through dynamic sending of the detection packet and on-demand detection processing, and the processing burden of equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of link service quality detection, in particular to an explicit path-based multi-link state detection method. Background technique [0002] At present, with the continuous development of data transmission technology, when sending data packets, the display path is used to send data packets based on the data link layer. detection. Explicit paths, similar to paths in MLPS or segment routing. In the prior art, when multi-links are detected, during the detection process, only the convergence process can be detected, that is, it depends on the data packets returned by the detected end, and cannot actively converge, and the interval between detection packets and the final calculated results Without smoothing, the mutation of the detection value is relatively large, and it cannot adapt to links of different qualities, and the application range is small. Contents of the invention [0003] The present invention a...
