A METHOD FOR IMPLEMENTING THE SYNCHRONIZATION OF THE TIMING SOURCES IN THE NETWORK

摘要

The present invention discloses a method for realizing automatic synchronization of timing source in network, applied to a ring including more than one network node, each network node executing the following steps: a. selecting a timing source with the highest quality from the timing source currently available for selection according to the timing source quality states, synchronizing the selected timing source, and taking the selected timing source as an available timing source for other network nodes; b. detecting whether the synchronized timing source is from a network interface connected to another network node, if so, setting the timing source quality state to be sent to the network node as a non-synchronous source state; otherwise, proceeding to step c; c. setting the timing source quality state to be sent to all connected network nodes except the network node said in step b as the quality state of the synchronized timing source. By the method, automatic selection and APS (Automatic Protection Switch) of timing source in local networks can be realized.
