Multimedia Networking Abstractions with Quality of Service Guarantees

The concept of schedulable region previously introduced to broadband networks with quality of service guarantees is extended to multimedia devices such as audio/video processing and disk storage units. The resulting multimedia capacity region characterizes the amount of resources a physical device is able to provide under quality of service constraints. The modeling methodology supports a straightforward association of resources with logical objects and, thereby, the mapping of logical objects onto physical objects with quality of service guarantees. Examples showing the size and shape of the multimedia capacity region of various physical devices are given.
