Abstract

Accurate OWD (one-way delay) measurement has a relevant role in network performance estimation and consequently in application design. In order to estimate OWD accurately it is essential to consider some parameters which influence the measure, such as operating system (OS) loaded on the PC, the treads, and the PC synchronization in the network. Due to the large research interest towards synchronization aspects, the authors have chosen to consider this parameter first. For this reason, three synchronization methods based on NTP (network time protocol), on GPS (global positioning system), and on IEEE 1588 standard are described and compared showing the advantages and disadvantages of the analyzed methods
