Abstract
Transparently changing the distribution of objects in a distributed system (application, service) at runtime is a way to improve service continuity and performance. For instance, it enables to transparently shutdown execution nodes for necessary maintenance operations. Moreover, optimizing service execution resources consumption, while improving service response time, is a key to both client and service provider satisfaction. However, previous work on load balancing has globally shown practical difficulties in getting effective such an approach. In the context of advanced telecommunication service execution environments, this paper proposes to revisit preemptive dynamic load balancing, by showing an experiment based on the combination between synchronous programming-based reactive objects, a flexible object request broker and a mobile agent framework. We present a full Java-based architecture, including a service example, and we show how peculiarities of synchronous programming give a chance to support low-cost preemptive mobility (also known as strong mobility), and to easily give a relevant computer-independent load indicator.
