Method for updating clock synchronization topology, method and device for determining clock synchronization path

摘要

The present application relates to the field of communications, and in particular to a method of updating clock synchronization topology, a method and device for determining clock synchronization paths. The method comprises the steps of receiving a first packet from a first network element, wherein the first packet includes clock synchronization capability information of the first network element, and the first network element is in the first network. The network element, the first network element having clock synchronization capability, and updating the clock synchronization topology of the first network based on clock synchronization capability information of the first network element. Further, the method determines a first clock synchronization path from the clock injection node of the first network to the first network element based on the request of the first network element and the clock synchronization topology of the first network It further includes a step. The clock synchronization topology is automatically updated based on the clock synchronization capability information of the network element to determine the clock synchronization path and reduce the cost of deploying the clock synchronization path.
