发明名称 METHOD AND DEVICE FOR DETECTING 1588 TIMING ERROR BETWEEN NETWORK ELEMENTS
摘要 <p>A method and a device for detecting a 1588 time error between network elements are disclosed. The method includes: a 1588 time network is established for an entire network; when it is required to detect a 1588 time error between a network element and its opposite network element, the network elements transmit, probe packets, each including a local timestamp to each other; and the network element receiving a probe packet calculates, according to a preset time difference algorithm, a time difference between the local timestamp and the timestamp in the probe packet, determines, according to the time difference, whether there is a failure in a detection path, and reports an alarm when there is a failure in the detection path. The disclosure prevents erroneous time transmission due to the time error, thus ensuring the network stability.</p>
