Abstract: For the problems of clock synchronization in one-way network performance measurement. This paper puts forward the optimizing goal of minimizing normal distance. And the clock synchronization optimization algorithm which improves the accuracy of one-way network delay measurement is deduced based on the optimizing goal. Finally, the algorithm proves effective by analyzing an actual network delay measurement result.
