QoS service routing in one-to-one and one-to-many scenarios in next-generation service-oriented networks

The QoS service routing problem has recently emerged as a consequence of the increasingly accepted distributed and composable services model. 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 formation issues, that make solutions for QoS data routing inapplicable to QoS service routing. We study this problem both in one-to-one and one-to-many application scenarios, so that despite the fact that the component services are located distributively in multiple hosts, the system can still provide integrated services seamlessly and efficiently.
