On the scope of end-to-end probing methods

A generic sample path based analysis of a multiple hop model of a network route carrying probe traffic and cross traffic is given. It provides a unifying context for active and passive end-to-end measurement techniques, and a framework to enhance existing and to generate new estimation methods. Novel aspects include focusing on delay variation and allowing general probe stream definitions. All multihop queueing effects acting on probes are identified and four canonical measurable signatures are defined and illustrated using simulation and real measurements.
