Towards Real-Time Performance in a Scalable, Continuously Available Telecom DBMS.

Abstract

A database for telecom applications must satisfy the same demanding requirements as the other components in the telecom network with respect to availability, scalability, and real-time performance. Unfortunately it is difficult to provide state-of-the-art realtime service without sacrificing the other. ClustRa is a parallel and distributed telecom DBMS designed as a careful balance between these requirements. The filosophy has been to provide sufficient real-time capabilities for telecom applications. This paper describes the architecture of ClustRa, its real-time features and a performace evaluation. 1 Introduction ClustRa is a telecom database management system [7]. It is built to meet the combined requirements from modern telecommunication applications like intelligent networks (IN) and mobile telephony. IN was introduced in the 80's to support new types of telecom services, e.g. terminal- (UPT) and service mobility, virtual private nets, and credit card calling. To achieve rapid d...
