Implementing Differentiated Services in a Real-Time Database Simulator

ID: LiTH-IDA-Ex-ING-04/005-SE

The demand for real-time data services has increased lately. Applications are becoming more demanding and require fresh data. Applications include for example stock markets and telecommunication. These systems are dynamic and the workload cannot be predicted and therefore they can be overloaded. Transactions in these systems can be of different importance. Therefore we want to have real-time databases with differentiated services where more important transactions are always processed before less important transactions. Research in the area of Quality of Service for real-time databases is being done. Sophisticated control algorithms have been developed and for testing these in different configurations we need a simulator framework that allows us to see how they behave for different transaction workloads. A simulator for real-time databases has been developed but it does not have the ability to simulate differentiated services. The goal with this project is to implement differentiated services into this simulator. Implementing this involves rewriting a great deal of the original code and implement new classes. The result is a simulator that has the ability of simulating a real-time database with differentiated services. We verified its correctness by several tests. This simulator will help computer scientists to develop and test more advanced algorithms in the future.

Keywords: Quality of Service, Differentiated Services, Real-time Databases, Simulators
