ABSTRACT

Developing distributed software systems by assembling commercial-off-the-shelf (COTS) software components has well-known advantages of reducing the development cost and time to market. However, the component-based software development poses some new problems and challenges due to its use of a different underlying process from traditional software development approaches. One of the major challenges is the compositional reasoning about the system Quality of Service (QoS). Compositional reasoning about system QoS is necessary in (COTS) component-based software development. It allows the static validation of the QoS of a software system based on the QoS assured by individual software components. In this paper, an empirical QoS composition reasoning approach is proposed and some preliminary results are discussed.
