Software Performance Evaluation Utilizing UML Specification and SRN Model and Their Formal Representation

Abstract—Performance assessment should be included in the software development process to ensure the quality of the software in operation. Hence, this paper introduces a performance modeling framework for a distributed software system that proposes a transformation process from a high level Unified Modeling Language (UML) notation to a Stochastic Reward Net (SRN) model. The model is solved for relevant performance metrics. In order to capture the system dynamics through our modeling framework, we outline a specification style that focuses on the UML collaboration and activity as reusable specification building blocks, while UML deployment diagram identifies the physical components of the system and the assignment of software artifacts to the identified system components. Efficient deployment mapping of software components on the available physical resources of the system is investigated by deriving the cost function. The UML specification presented in this work facilitates to delineate the complete behavior of the system components according to the functionalities they offer and has been utilized as input for model transformation. The paper describes the mapping rules for defining the transformation process from the UML model to the SRN model. In addition, the tool support of the framework is introduced that ensures automatic translation from UML to SRN model and evaluation of the SRN model. The applicability of our framework is demonstrated in the context of performance modeling of distributed systems.

Index Terms—Performance, reusability, service deployment, UML, SRN.
