AI Technical Summary

Problems solved by technology

If the path between node m and node n is faulty, nodes X and node Y cannot receive BFD detection packets within a certain period of time, and the path between node X and node Y is judged to be faulty, but the specific path fault location cannot be known
[0005] Therefore, the existing BFD mechanism can only perceive the fault of the detected path, but cannot perceive the location of the fault point, and subsequent manual positioning is required, resulting in long maintenance and positioning process, high cost, and low operation and maintenance efficiency

Abstract

The invention discloses a detection method and device, relates to the field of communication, and aims to shorten fault positioning time and cost and improve operation and maintenance efficiency. According to the specific scheme, the method comprises the following steps: obtaining a detection message comprising a feature identifier, wherein the feature identifier is used for indicating the measurement of the transmission quality of the detection message; the detection message is used for detecting the transmission quality of a path from the second node equipment to the third node equipment; and obtaining a transmission quality parameter of the detection message in the first node device according to the feature identifier in the detection message.

Description

technical field [0001] The embodiments of the present application are in the field of communications, and in particular, to a detection method and device. Background technique [0002] With the widespread deployment of network applications, network interruption may affect normal business operations and cause heavy losses. In order to reduce the impact of link and device failures on services and improve network reliability, network devices need to detect communication failures with adjacent devices as soon as possible, so that timely measures can be taken to ensure normal services. [0003] Bidirectional forwarding detection (BFD) is a common technique for detecting path connectivity. In the BFD mechanism, nodes at both ends of the detected path periodically exchange detection packets. When one end fails to receive the detection packets within a certain period of time, it is determined that the path is faulty. [0004] like figure 1 In the illustrated packet transmission s...
