SONET-based integrated digital loop carrier (IDLC) software reliability modeling

An overview of the mathematical framework for the nonhomogeneous Poisson process (NHHP) model, and the design and implementation of the software reliability test tool are presented. The operational profile-driven testing in measuring software quality from the user's point of view is presented. It is shown how NHPP can be used to predict software failure behavior and estimate how much testing time is needed to achieve given reliability objectives. It is recommended that building an automated test tool will save time and improve accuracy in failure identification.
