Distributed Object Group Framework with Dynamic Reconfigurability of Distributed Services

Abstract

In this paper, we constructed the Distributed Object Group Framework(DOGF) which is a reconfigurable architecture supporting dynamically adaptation of distributed services. We also developed the distributed application simulator to verify the adaptability and reconfigurability of our framework. The DOGF provides appropriate grouping of distributed objects for executing given distributed applications as the point of view of a single logical view system, and supports the adaptive distributed services for dynamic reconfiguration of distributed application. In constructing procedure of the DOGF, we designed the distributed services that consist of the objects supporting service, the load balancing service, and the real-time service. We also implemented the managing technique for dynamic reconfiguring the distributed services. Finally, for verifying whether the DOGF can support the dynamic reconfigurability of distributed services or not, we developed the Defence System against Invading Enemy Planes(DSIEP) simulator as a practical use of distributed application with real-time property on the DOGF. From this, with adaptation of given load balancing policies, we analyzed the average execution times and the deadline violation rates as the execution results for the client’s request.
