The substantial overhead of performing internal network monitoring motivates techniques for
inferring spatially localized information about performance using only end-to-end
measurements. In this paper, we present a novel methodology for inferring the queuing
delay distributions across internal links in the network based solely on unicast, end-to-end
measurements. The major contributions are: 1) we formulate a measurement procedure for
estimation and localization of delay distribution based on end-to-end packet pairs; 2) we …
