Improving scalability of event-driven distributed objects architectures
Daniel Mencnarowski, Krzysztof Zieli ski · Software Practice and Experience · 2000
The goal of this paper is to present practical techniques for improving the scalability of a distributed objects architecture built around an event-driven paradigm and the evaluation of their effectiveness in the case of location systems. As a case study, the ABng location system constructed using a publisher/subscriber pattern over a CORBA compliant middleware is presented. The main contribution of this paper is the elaboration and evaluation of three main concepts that play a crucial role in improving the scalability of event-driven architectures: events dissemination quality of service, notification tree based events-routing, and transparent multicast event-channel notification service. The applicability and efficiency of these techniques have been verified in practice by the ABng system implementation and performance testing. Copyright © 2000 John Wiley & Sons, Ltd.
