Automating QoS Based Service Selection

The presence of multiple services sharing a common functional interface necessitates differentiating between them on the basis of their performance. However advertised quality of service (QoS) alone cannot paint the true picture of how the service has performed so far and how it will continue to function in the near future. This information is crucial for service selection. In this paper, we outline a method of monitoring and extrapolating service performance and using the same for automated service selection process.
