Abstract

The invention discloses a network clock monitoring method and a network clock monitoring device used for monitoring the state of a network clock. The clock network monitoring method comprises the following steps: acquiring clock data of all equipment accessing a network; visualizing the clock data to obtain a topological network diagram of the clock data; setting a clock source for any equipment in the topological network diagram, and monitoring the flow directions of the clock sources according to the topological network diagram to obtain a monitoring result; and triggering alarm information when the monitoring result shows that the clock sources of the equipment form a ring or are in an interlocking state in the topological network diagram. By adopting the technical scheme of the invention, PTN network clock self-monitoring is realized, the equipment of which the clocks form a ring or have reduced quality can be found actively, and the workload of network maintenance is reduced.

Description

technical field [0001] The invention relates to the field of mobile communication, and more specifically, to a method and device for monitoring a network clock. Background technique [0002] With the continuous development of the network and the rapid expansion of various services, the requirements for the PTN (Packet Transport Network) network are getting higher and higher. In order to avoid frequent pointer adjustments caused by poor PTN network clocks, and even affect the normal operation of the business Operation, the clock looping or interlocking warning and optimization of the PTN network play an important role in ensuring the stability and reliability of the entire network. [0003] At present, in the process of PTN communication network networking, all PTN devices need to be configured for clock synchronization. The clock synchronization of transmission devices adopts the master-slave synchronization method. It is required that the timing of the clocks of the network...
