QoS Service Routing for Supporting Multimedia Applications

Free registration required

Executive Summary

Based on the distributed and composable service model, the QoS service routing problem for supporting multimedia applications has emerged. Different from the conventional QoS data routing, QoS service routing presents additional challenges caused by the service availability, service dependency, and resource requirement heterogeneity issues, which 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 (Service configuration selection is done separately from service path finding), so that they either become inapplicable to new environments/metrics or the computed paths are sub-optimal.
