The invention discloses a method, device and system for detecting clock synchronization, which relate to the field of network detection and are used to solve the problems caused by using a clock performance analyzer to detect clock synchronization between network elements after completing the clock deployment of the mobile bearer network. The problem of high costs. The method provided by the present invention specifically includes: the downstream network element device sends a clock synchronization detection message containing negotiation parameters to the upstream network element device, and records the local frequency value of the downstream network element device within a certain period of time, and the upstream network element device Adjust the frequency value of the data flow sent to the downstream network element equipment according to the negotiation parameters, and then judge whether the actual value of the clock performance index calculated according to the two recorded frequency values meets the expected value of the clock performance index determined according to the negotiation parameters . The embodiments of the present invention are mainly used in the process of detecting clock synchronization of network element equipment.
Description
Technical field [0001] The invention relates to the field of network detection, in particular to a method, equipment and system for detecting clock synchronization. Background technique [0002] In the mobile bearer network, by setting the clock tracking relationship of each network node in the network, the clock synchronization of the entire network is ensured. Therefore, it is necessary to deploy the clock of the mobile bearer network. When the clock is deployed, deployment may occur Successful and normal operation, but because the third-party equipment or network between the two network elements does not support physical layer synchronization or the physical layer synchronization function is faulty, after a period of time, the clock synchronization will be abnormal, which will cause the two networks The network between elements is unavailable or the network usage is affected. Therefore, it is necessary to detect the clock synchronization between each network element in the net...
