Compact Markov-modulated models for multiclass trace fitting

Casale, Giuliano; Sansottera, Andrea; Cremonesi, Paolo (2016)
Projects: EC | DICE (644869)
Markov-modulated Poisson processes (MMPPs) are stochastic models for fitting empirical traces for simulation, workload characterization and queueing analysis purposes. In this paper, we develop the first counting process fitting algorithm for the marked MMPP (M3PP), a generalization of the MMPP for modeling traces with events of multiple types. We initially explain how to fit two-state M3PPs to empirical traces of counts. We then propose a novel form of composition, called interposition, whic...

Automated Parameterization of Performance Models from Measurements

Casale, Giuliano; Spinner, Simon; Wang, Weikun (2016)
Projects: EC | DICE (644869)
Estimating parameters of performance models from empiri- cal measurements is a critical task, which often has a major in uence on the predictive accuracy of a model. This tuto- rial presents the problem of parameter estimation in queue- ing systems and queueing networks. The focus is on reliable estimation of the arrival rates of the requests and of the ser- vice demands they place at the servers. The tutorial covers common estimation techniques such as regression methods, maximum-likeliho...
