Performance of relational database management systems in intelligent networks and mobility environments

The handling of large amounts of data is crucial for operation and management of telecommunication systems like intelligent networks and mobility environments. Requirements like reliability, security and performance have been addressed by the database community for many years which is reflected in mature relational database management systems. We look at relational database systems to find out if and how they can be used to satisfy the database requirements of telecommunication applications. In the INDIA project we adopted relational database systems to handle the distribution and performance requirements of telecommunication applications, especially of intelligent networks. Our method is called atomic delayed replication (ADR). ADR allows a dynamic reconfiguration of data distribution for load balancing and makes migration of data to different nodes easy. We integrated ADR into the Philips IN prototype. We give a brief characterization of our ADR approach and carry out a performance evaluation. Further performance evaluation was done using an analytical model. Some major results are sketched. We applied our ADR approach to another application area in telecommunications, namely, a city-wide PCS (personal communication services) environment.
