Abstract

As object-oriented distributed systems, e.g. those based on CORBA, Java, and DCOM, are entering the mainstream of information technology, it is increasingly important to predict and understand their performance characteristics. To support this need, we describe a framework that allows UML diagrams to be used for building performance models for such systems. A mapping is proposed from the high-level UML notation to queuing networks with simultaneous resource possessions, so that the models can be solved for the relevant performance metrics. The main goal of the framework is to support performance engineering and, thus, flexibility and ease of use have been emphasized.
