It is well known that measuring the one-way delay of the VoIP packets is a daunting task. The challenge lies in the fact that the Internet implicitly enforces the end-to-end principle. This means the endpoints are expected to operate independently. Without a synchronized timing, it is difficult for an endpoint to measure the one-way delay. This paper presents the refined version of the novel VoIP measurement methodology called Sync & Sense of Periodic Stream that can overcome such a challenge. Sync & Sense is unique in that it can virtually synchronize the transmission and reception timing of the VoIP session without requiring a synchronized clock. Our performance study shows that Sync & Sense can accurately measure the one-way network delay of the VoIP packets (without propagation delay). While time skew is very common in any systems involving a clock, we also discuss this issue and how Sync & Sense can deal with the time skew without requiring a synchronized clock.
