TwoEagles: A model transformation tool from architectural descriptions to queueing networks

Abstract

We present the implementation of a methodology for the modeling, analysis, and comparison of software architectures based on their performance characteristics. The implementation is part of a software tool that is called TwoEagles, which extends the architecture-centric tool TwoTowers - based on the stochastic process algebraic description language Æmilia - and integrates it into Eclipse. The extension consists of a Java-coded plugin that we have called AEmilia-to-QN. This plugin transforms Æmilia descriptions into queueing network models expressed in the XML schema PMIF, which can then be rendered via the QN-Editor tool or analyzed by multiple queueing network solvers that can be invoked through the Weasel web service. © 2011 Springer-Verlag.
