Performance Analysis of the Simplicity Project: a Layered Queueing Network Approach
Francesco Lo Presti · 2005
Abstract — As technology develops, a broader and broader range of heterogenous ICT devices and network-based services are made available to users. As for today, this often results in an enormous burden of complexity on users, service providers and service operators. To overcome these limitations, the IST Simplicity project aims to ease the user interaction with devices and the use of services and functionalities. The Simplicity architecture revolves around a system of brokers which provide a layer able to decouple user needs and user devices, as well as service deployment and fruition, from the underlying networking and service support technologies. In this paper, we address the performance of the Simplicity system. By using the Layered Queueing Network formalism, we propose and study a model of the Symplicity architecture. The analysis allows us to explore in a simple and efficient way the system performance under different setting and to explore several alternatives.
