Abstract

Based on the distributed and composable services model, the QoS service routing/composition problem has emerged as middleware support for multimedia applications. Different from the conventional QoS data routing, QoS service routing presents additional challenges caused by the service functionality, service dependency, resource requirement heterogeneity, and loop issues that make solutions for QoS data routing inapplicable to QoS service routing. Existing solutions for addressing this problem are either not generic enough or not integrated, so that they either become inapplicable to new environments/metrics or the computed paths are sub-optimal. This paper presents a generic and integrated approach for computing optimal service paths, and shows an aggregate performance function - ℱ - that optimizes several QoS metrics at the same time. Simulations show that ℱ is superior, and integrating service configuration selection with service path finding is desirable.
