Performance evaluation of a DVB-H enabled mobile device system model

Abstract

In this experience report, we present experiences we have gained in applying performance engineering techniques during the design of a DVB-H enabled handheld device. The modelling methodology we applied uses UML 2.0 to model the system following a strict separation of architectural and behavioural aspects of the systems. From sequence diagrams and composite structure diagrams, a queueing network is generated for the analysis of the system performance. The configuration of the hardware resources and the resource demands is done using the standard SPT-profile. We describe our implementation and its seamless integration into a UML 2.0 CASE tool. Finally, the paper outlines lessons learnt during the design process which may be used to enhance the methodology.

“…Software performance engineering methods (SPE) [3] use interpreted Unified Modelling Language (UML) diagrams to model the system and soft-ware under study [17], [20], [26]. Since UML does not allow for the modeling of nonfunctional aspects many authors apply the UML Profile for schedulability, Performance, and Time Specification (SPT) [22] to enhance the diagrams with the necessary semantics [17], [26]. The UML Profile for Modeling and Analysis of Real-Time and Embedded systems (MARTE) is the successor of the SPT profile, allows for a detailed modeling of performance aspects, and supports UML 2.…”
