Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] The 1588 time error detection method between network elements of the present invention includes two types: the 1588 time error detection method between adjacent network elements and the 1588 time error detection method between non-adjacent network elements, which can be defined as the two methods of the present invention Modes, namely the pre-activation mode and the on-demand mode. Users can configure the detection mode of network elements according to their needs. The default is the pre-activation mode.

[0022] like figure 1 As shown, it is a ...

Abstract

The invention discloses a method and device for detecting 1588 time errors between network elements. The method is as follows: the entire network establishes a 1588 time network. The detection message is sent to the peer network element; the network element receiving the detection message calculates the time difference between the local timestamp and the time stamp in the above detection message according to the preset time difference algorithm, and judges whether the detection path is faulty based on the above time difference , if so, report to the police. The invention prevents time error transmission caused by time error and ensures the stability of the network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for detecting 1588 time errors between network elements. Background technique [0002] With the rapid development of network informatization, the PTN (Packet Transport Network) network composed of a large number of network devices is becoming larger and more complex, and 1588 time will produce time errors during network transmission. For the master and slave ports between network elements, the 1588 time transfer process can be corrected and compensated, but whether the 1588 time is synchronized between the passive port and the master port of the network element is unknown. [0003] The detection of time error is very important. It can remind the network operator in time that there is a time error on this link. If the error value cannot be detected in time, the 1588 time error on the link may become larger and larger, and eventually the time cannot be synchron...
