Setwise and filtered gibbs samplers for teletraffic analysis
Lachlan L. H. Andrew, Guoqi Qian, Felisa J. Vázquez-Abad
Article No.: 7
DOI: 10.1145/1734222.1734223

A setwise Gibbs sampler (SGS) method is developed to simulate stationary distributions and performance measures of network occupancy of Baskett-Chandy-Muntz-Palacios (BCMP) telecommunication models. It overcomes the simulation difficulty...

Information models for queueing system simulation
Theresa M. Roeder, Lee W. Schruben
Article No.: 8
DOI: 10.1145/1734222.1734224

When planning simulations of large-scale systems, it is important to anticipate what information is required to model the system and obtain desired output. This can be done without tying the study to a specific simulation package or language. It...

Asymptotically optimal allocation of stratified sampling with adaptive variance reduction by strata
Reiichiro Kawai
Article No.: 9
DOI: 10.1145/1734222.1734225

To enhance efficiency in Monte Carlo simulations, we develop an adaptive stratified sampling algorithm for allocation of sampling effort within each stratum, in which an adaptive variance reduction technique is applied. Given the number of...

CDNsim: A simulation tool for content distribution networks
Konstantinos Stamos, George Pallis, Athena Vakali, Dimitrios Katsaros, Antonis Sidiropoulos, Yannis Manolopoulos
Article No.: 10
DOI: 10.1145/1734222.1734226

Content distribution networks (CDNs) have gained considerable attention in the past few years. Hence there is need for developing frameworks for carrying out CDN simulations. In this article we present a modeling and simulation framework for CDNs,...
