Web software reliability analysis with Yamada exponential testing-effort

How to evaluate the reliability of Web software has been more and more important since various services will be provided through the web servers. The evaluation is usually made by the reliability models based on workload measurements. This paper considers applying the NHPP software reliability model with Yamada exponential testing-effort function (TEF) to web software reliability analysis. By using the workload data and failure data from IIS server logs of ICRMS website, it shows that the method of reliability data mining is useful and the proposed model can be used to characterize the actual workload patterns more faithfully during the website running.
