Abstract :
A lot of network management applications rely on the measurement of the delay experienced by packets between two observation points (one way delay). In this paper we describe an implementation of a passive OWD measurement system composed of a set of synchronized measurement points that observe selected packets and report transit timestamps to a collector station. Measurement points can be standalone probes or be embedded in routers. We first describe the system design and then focus on the implementation issues of the two building blocks of the system, the measurement points and the one way delay data collector.
