QoE支持多层多媒体应用

QoE Support for Multi-Layered Multimedia Applications

Hengky Susanto, ByungGuk Kim, Benyuan Liu

摘要:

拥塞控制协议和带宽分配问题常被归结为网络效用最大化(NUM)框架。NUM的现有解决方案通常专注于单层应用程序。随着诸如视频流的应用的重要性和流行性的增长,在NUM公式化中解决这些多层多媒体应用的用户效用函数变得至关重要。在本文中,我们提出了一个新的多层次的用户效用模型,利用人类的视觉感知和体验质量(QoE)从计算机图形学和人机交互(HCI)领域的研究。使用这种新的效用模型来研究网络活动,我们证明了解决NUM与多层效用是棘手的,并且速率分配和网络定价可能会由于特定于多层应用的用户行为而振荡。为了解决这个问题,我们提出了一种新的方法,准入控制,以确保服务质量(QoS)和体验质量(QoE)。

英文摘要:

Congestion control protocol and bandwidth allocation problems are often formulated into Network Utility Maximization (NUM) framework. Existing solutions for NUM generally focus on single-layered applications. As applications such as video streaming grow in importance and popularity, addressing user utility function for these multi-layered multimedia applications in NUM formulation becomes vital. In this paper, we propose a new multi-layered user utility model that leverages on studies of human visual perception and quality of experience (QoE) from the fields of computer graphics and human computer interaction (HCI). Using this new utility model to investigate network activities, we demonstrate that solving NUM with multi-layered utility is intractable, and that rate allocation and network pricing may oscillate due to user behavior specific to multi-layered applications. To address this, we propose a new approach for admission control to ensure quality of service (QoS) and quality of experience (QoE).
