This paper uses a probe-based sampling approach to study the behavioural properties of Web server scheduling strategies, such as Processor Sharing (PS) and Shortest Remaining Proc...
Abstract. In this paper we describe a formalism which uses the stochastic process algebra PEPA as the inscription language for labelled stochastic Petri nets. Viewed in another way...
Web Services are an emerging software technology that employ XML to share and exchange data. They may serve as wrappers for legacy data sources, integrate multiple remote data sou...
Modeling the Internet infrastructure is a challenging endeavor. Complex interactions between protocols, increasing traffic volumes and the irregular structure of the Internet lea...
A flash crowd is a surge in traffic to a particular Web site that causes the site to be virtually unreachable. We present a theoretical model of flash crowd events and evaluate...

We present a technique for defining and extracting passage-time densities from high-level stochastic process algebra models. Our high-level formalism is PEPA, a popular Markovian...
