Information Feedback Model to Address Software Reliability in an Integrated Environment

Concepts borrowed from the data networks and communication world are extremely useful to model software reliability. Each of the modules in the integrated environment will have a predefined failure rate that is analogous to the probability of packet drop in a data network. The usage of this feedback information is well known. The novelty of this presentation lies in the adoption of the predicted version of this feedback information for further enhancing the reliability and defining the appropriate "Quality of Service" (QoS) parameters that suit the integrated environment. It will be shown that the prediction step will have a profound influence on the absolute reliability, the relative reliability of different components, etc., and helps to arrive at a system with minimal failures.

Key Words: Information Feedback, Failure Prediction, Quality of Service, Abstract Organization of the Software
