Abstract

Embodiments of the present invention relate to the field of communication technologies, and disclose a time network node management method, device, and time network node. The method includes: performing time synchronization on all the time network nodes in the time network; calculating in real time the absolute value of the time deviation between any time network node in the time network and other time network nodes, and determining any time network node. The minimum value of the absolute value of the time deviation between the time network node and other time network nodes; compare the minimum value of the absolute value of the time deviation and the preset convergence deviation threshold to determine whether there is an abnormal node; if there is an abnormal node, adjust the The time value of abnormal nodes or dynamically adjust the time value of all time network nodes. In the above manner, the embodiment of the present invention realizes efficient and stable management of time network nodes, and improves the real-time performance and time precision of the network.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a management method and device of a time network node and a time network node. Background technique [0002] During the networking of network nodes, the master clock of each network node is the clock reference source for synchronizing all other devices in the network, and the synchronization accuracy between master clock nodes also determines the performance of the entire network. As the real-time requirements in the network are getting higher and higher, the requirements for time accuracy in the network are also getting higher and higher, so the network time of each node has an increasing impact on the entire network. [0003] At present, most of the methods for managing network nodes are local management methods, that is, according to the state information of the local node is saved locally, and then the management node reads out the information of each no...
