Performance Engineering of Component-Based Distributed Software Systems

Abstract

The ability to estimate the future performance of a large and complex distributed software system at design time can significantly reduce overall software cost and risk. This paper investigates the design and performance modeling of component interconnection patterns, which define and encapsulate the way client and server components communicate with each other. We start with UML design models of the component interconnection patterns. These designs are performance annotated using an XML-type notation. The performance-annotated UML design model is mapped to a performance model, which can be used to analyze the performance of the software architecture on various configurations.
