Performance modelling of database servers in a Telecommunication Service Management system

Author

Summary, in English

Resource optimization mechanisms, as admission control and traffic management, require accurate performance models that capture the dynamics of the system during high loads. The main objective of this paper is to develop an accurate performance model for database servers in a telecommunication service management system. We investigate the use of a server model with load dependency. Concurrent requests add load to the system and decrease the server capacity. We derive explicit equations for the state probabilities, the average number of jobs in the system and the average response times. Further, we present some heuristics on how to tune the parameters for given measurement data. Also, using testbed experiments, we validate that the model accurately captures the dynamics of a database server with write-heavy workload.
