This volume is dedicated largely to the performance-oriented design of modern computernetworks, bothwiredandwireless. ItistheconsequenceoftheTutorial Session which was held on 12th October 2003, preceeding the IEEE Computer Society's Symposium on Modeling, Analysis and Simulation of Computer and Telecommunication Systems, held in Orlando, Florida. In addition to the core tutorialpresentations, whichcoveredbothadvancesinnetworkqualityofservice (QoS) and in performance evaluation methodology, we felt that it would be useful to assemble a volume in the Lecture Notes in Computer Science series which would also include speci?c application areas of performance modeling and measurements. Thus the current volume includes three parts: - a ?rst part that speci?cally addresses performance and QoS of modern wired and wireless networks; - a second one that discusses current advances in performance modeling and simulation; and - a ?nal part that addresses other speci?c applications of these methodologies. The network-oriented portion of the volume itself comprises three complem- tary topics: - a ?rst group of chapters deals with novel designs and new issues related to broad-based network performance and QoS, without limitations concerning the connection technologies that are being used; - a second group addresses the wireless context; and - a ?nal grouping of contributions considers the topic of wireless ad hoc n- worksmorespeci?cally. The part of the volume dealing with methodologies discusses the software s- ci?cation of models, the use of certain formalisms such as Petri nets, and some recent advances in simulation. Finally, the third part of the volume discusses other performance applications related to scheduling and to speci?c architec- res.

This book constitutes the post proceedings of the 28th International Symposium on Modelling, Analysis, and Simulation of Computer and Telecommunication Systems, MASCOTS 2020, held online -due to COVID -19- in Nice, France, in November 2020. The 17 full papers presented were carefully reviewed and selected from 124 submissions. The symposium collected the most relevant papers describing state-of-the-art research in the areas of the performance evaluation of computer systems and networks as well as in related areas.

This book presents the tutorial lectures given by leading experts in the area at the IFIP WG 7.3 International Symposium on Computer Modeling, Measurement and Evaluation, Performance 2002, held in Rome, Italy in September 2002.The survey papers presented are devoted to theoretical and methodological advances in performance and reliability evaluation as well as new perspectives in the major application fields. Modeling and verification issues, solution methods, workload characterization, and benchmarking are addressed from the methodological point of view. Among the applications dealt with are hardware and software architectures, wired and wireless networks, grid environments, Web services, and real-time voice and video processing.This book is intended to serve as a state-of-the-art survey and reference for students, scientists, and engineers active in the area of performance and reliability evaluation.
