Abstract

This paper proposes a new performance measurement scheme which can infer performance and/or quality experienced by individual user, organization and application, via a scalable and lightweight measurement way. The proposed scheme is based on change-of-measure framework and is an active measurement transformed by using passively monitored data. We give the theoretical basis of the proposed scheme and show its typical implementations for inferring the delay distributions. The validation of the implementations of the proposed scheme is investigated through simulation with respect to both the accuracy of estimation and the amount of the extra traffic added by active measurement.
