According to the ITU-T, the quality of a multimedia service is defined by a set of user-related parameters: delay, delay variation, and information loss. To provide multimedia applications with end-to-end QoS guarantees, an efficient resource reservation and management strategy has to be adopted. This paper presents a schema for satisfying multimedia QoS parameters over a real-time operating system, which adopts the rate monotonic as a scheduling algorithm. Such a schema is implemented in a real-time based architecture for QoS multimedia provisioning. This architecture allows to define classes of services with different quality attributes concerning the multimedia data delivery.

Abstract
According to the ITU-T, the quality of a multimedia service is defined by a set of user-related parameters: delay, delay variation, and information loss. To provide multimedia applications with end-to-end QoS guarantees, an efficient resource reservation and management strategy has to be adopted. This paper presents a schema for satisfying multimedia QoS parameters over a real-time operating system, which adopts the rate monotonic as a scheduling algorithm. Such a schema is implemented in a real-time based architecture for QoS multimedia provisioning. This architecture allows to define classes of services with different quality attributes concerning the multimedia data delivery.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
