QoS based resources management model for supporting multimedia services

This paper proposes the QoS based resource management architecture which supports the large scale distributed systems under heterogeneous environment. The architecture introduces a couple of key concepts such as abstractions and algorithms. Abstractions capture the three perspectives found in all systems: application, resource, and system, on the other hand algorithms manage system resources based on information in the three abstractions. We also explain the on-line resource management flow as well as the benefit function which specifies the level of benefit accrued to the application user as a function of the level of service provided by the system. At the end of the paper, the QoS based resource management applied to the teleseminar application is described to show its practical utilization
