摘要

We propose and analyze quality of service (QoS) control algorithms for video servers designed to provide differentiated video streaming services. The design concepts are based on resource reservation and benefit optimization so that resources are reserved dynamically and adaptively for different QoS levels in response to the changing workload of the system, with the objective of maximizing the benefit throughput obtainable by the system. We analyze the benefit throughput obtainable by the system for a baseline algorithm for which the QoS levels of admitted users are not changed during the service lifetime and a greedy algorithm that may raise QoS levels of admitted users due to resources being free from departure events. We validate the design of these two QoS control algorithms via a detailed simulation study.
