A model of the multichannel queuing system is considered. Each channel contains some service lines. There are several input flows. Each customer requires several lines to be serviced. If the channel does not have a sufficient number of service ...

The authors analyze the model of a queueing system consisting of two service channels. Each channel receives calls from several Poisson flows of different types. A call of each flow requires certain resource for its service. Threshold service ...

Inexact operators are developed to exploit the tolerance of an application to imprecisions. These operators aim at reducing system energy consumption and memory footprint. In order to integrate the appropriate inexact operators in a complex system, the ...

Many natural phenomena which occur in the realm of visual computing and computational physics, like the dynamics of cloth, fibers, fluids, and solids as well as collision scenarios are described by stiff Hamiltonian equations of motion, i.e. ...

Based on Lindley's recursive equations for G/G/1 systems, this paper proposes a Fast Discrete Event Simulation (FDES) model for queueing networks. Equations for multiplexer and de-multiplexer elements are presented, which allows to simulate not only ...

Lindley's recursion is an explicit recursive equation that describes the recursive relationship between consecutive waiting times in a single-stage single-server queue. In this paper, we develop explicit recursive representations for multiserver tandem ...

Studying program behavior is a central component in architectural designs. In this paper, we study and exploit one aspect of program behavior, the behavior repetition, to expedite simulation. Detailed architectural simulation can be long and ...

In this paper, we develop a fast simulation framework for IEEE 802.11-operated wireless LANs (WLANs), in which a large number of packets are abstracted as a single fluid chunk, and their behaviors are approximated with analytic fluid models and figured ...

A multiserver queuing system with recurrent input flows is considered. A fast simulation method is proposed for evaluation of stationary loss probability. It is based on the joint use of importance sampling and the central limit theorem. The estimates ...

A new fast simulatiom method for evaluation of unavailability of a repairable system is proposed. Failure-free operation time and repair time have distribution functions of a general type. It is proved that for components with significantly different ...

A new fast simulation method is proposed for evaluation of unavailability of a repairable system. Its idea is to order failure trajectories according to their ranks that promotes rational experiment organization. The estimates are unbiased and possess a ...

In this paper, we consider the performance analysis problem for a work conserving link with a large number of independent regulated inputs. For such a problem, we derive simple stochastic bounds under a general traffic constraint for the inputs. The ...

A significant difficulty when using Monte Carlo simulation for the performance analysis of communication networks is the long runtime required to obtain accurate statistical estimates. Under the proper conditions, importance sampling (IS) is a technique ...

Abstract: We present a new model for aggregated network traffic based on /spl alpha/-stable self-similar processes which captures the burstiness and the long range dependence of the data. We show how the fractional Gaussian noise assumption fails and ...

In this survey, key drivers in design methodology are provided that enable successful design of systems-on-a-chip for the highly competitive telecommunications market. Main components of a design environment are described that fulfill the requirements ...

This paper considers the problem of estimating, via simulation, extremely low packet loss rates in a voice-data multiplexer. The multiplexer gives priority to voice packets, unless the data queue length exceeds a threshold. To efficiently simulate such ...
