Performance Analysis of Distributed Real-Time Databased

In a distributed process control system, information about the behavior of physical processes is usually collected and stored in a real-time database which can be remotely accessed by human operators. In this paper we propose an analytic approach to compute the response time distribution of operator consoles in a distributed process control environment. The technique we develop is based on Mark...

Distributions of the Interdeparture Times in FCFS and Nonpreemptive Priority MMAP [2]/G [2]/1 Queues

This paper deals with single server queueing systems with two classes of customers and a correlated arrival process. The focus is on the interdeparture times of each class of customer. A uniform approach is introduced to find the Laplace–Stieltjes transforms of interdeparture times for queueing systems with equal priority and nonpreemptive priority, respectively. Algorithms can be developed for...

Compositional performance modelling with the TIPPtool

Stochastic Process Algebras have been proposed as compositional specification formalisms for performance models. In this paper, we describe a tool which aims at realising all beneficial aspects of compositional performance modelling, the TIPPtool. It incorporates methods for compositional specification as well as solution, based on state-of-the-art-techniques, and wrapped in a user-friendly gra...

ATM Rate-Based Congestion Control Using a Smith Predictor

This paper presents a feedback control algorithm for ATM congestion control in which source rates are adjusted according to VC queue lengths at intermediate nodes along the path. The goal is to ""ll in" the residual bandwidth, without exceeding a speciied queue threshold. In order to obtain this, we propose a simple and classical proportional controller, plus a Smith Predictor to overcome insta...
