摘要

现有的网络QoS模型不能充分反映高吞吐量、永远在线、非弹性多媒体应用所面临的挑战。为了更好地评估多媒体应用的需求和管理多媒体流的QoS提供，本文提出了一种基于实用的QoS模型，作为现有通信QoS模型的用户层扩展。从用户实验中导出网络损害效用函数，并与应用效用函数结合，对应用质量进行评价。通过仿真验证了所提出的QoS模型的有效性。

A Utility-Based QoS Model for Emerging Multimedia Applications

Existing network QoS models do not sufficiently reflect the challenges faced by high-throughput, always-on, inelastic multimedia applications. In this paper, a utility-based QoS model is proposed as a user layer extension to existing communication QoS models to better assess the requirements of multimedia applications and manage the QoS provisioning of multimedia flows. Network impairment utility functions are derived from user experiments and combined to application utility functions to evaluate the application quality. Simulation is used to demonstrate the validity of the proposed QoS model.
