Measuring Network One-way Transit Time

Network one-way transit time is one of the principal factors affecting network QoS. It is therefore important to measure it with sufficient accuracy. The measurements of network one-way transit time should not include host effects (time spent of the measurement hosts themselves) but be entirely attributable to delays incurred on the network. Furthermore, the measurements of network oneway transit time should not be affected by the relative offset and skew of the clocks of the measurement hosts. This paper proposes a methodology for such measurements. The accuracy achieved by the proposed method is sufficient to detect deteriorating network conditions.
