METHOD FOR DETERMINING CLOCK TRACE PATH AND METHOD OF CLOCK TRACE IN THE NETWORK

摘要

A method for determining clock trace path and method of clock trace in the network. Said method for determining clock trace path includes: first, in the network, the distributed network units or the centralized servers determine the shortest path arriving respective clock-source network unit in accordance to the preserved network topology information the weighting information of the clock trace link; and among the clock-source provided by the respective arrival clock-source network unit, determining the clock-source network unit wherein the clock-source is the best quality as the optimal clock-source network unit; hereafter, the distributed network units or the centralized servers will regard the determined path arriving the optimal clock-source network unit as the clock trace path. Said method of clock trace then is tracing the clock using the said clock trace path.
