This award will support the first of two anticipated workshops on tracking Quality of Experience (QoE) in the Internet. The workshops will bring together top researchers in academia and industry, as well as government representatives, to discuss ongoing work on the topic, and opportunities and potential frameworks for collaboration across the different disciplines. The intended outcome is a research agenda leading to better methods to measure and analyze the state of QoE in the current Internet and identify and localize the causes of QoE impairments. Considering the diversity of topics to consider, the organizers will ensure through announcements in a range of venues and targeted email that different research areas and perspectives are adequately represented.The term "Quality of Experience (QoE)" describes a user's subjective assessment of his or her experience using some application. Network engineers have in the past focused on Quality of Service: performance metrics such as throughput, delay and jitter, packet loss, and the like. But different performance as measured by QoS parameters only matters if it affects the consequential experience of users, as they attempt to use one or another application over the net. QoE impairments, which might include rebuffering for streaming video or excessive round trip latency for real time speech, are what really matter to the user. The goal of the workshops is to understand the state of research with respect to QoE, and specifically to contemplate a community agenda to integrate ongoing threads of QoE research into a collaboration, in order to measure and analyze the state of QoE in the current Internet and identify and localize the causes of QoE impairments.These meetings will bring together researchers in different areas critical to understanding QoE in the Internet - from network measurements, to experimental designs and human factors - and provide opportunities for cross-area research and collaboration. The outcome of the workshop will begin to define relevant measurements of broadband quality and help network providers to better understand where impairments are arising in the global Internet. These consequences should in turn lead to a better Internet experience for the typical user of the Internet. As well, the discussions at the workshop are intended to suggest new research collaboration for the network, systems and human computer interaction communities.

该奖项将支持两个关于跟踪互联网体验质量（QoE）的预期研讨会中的第一个。研讨会将汇集学术界和工业界的顶级研究人员以及政府代表，讨论正在进行的有关该主题的工作，以及不同学科之间合作的机会和潜在框架。预期的结果是一个研究议程，导致更好的方法来测量和分析当前互联网中的QoE状态，并识别和定位QoE损害的原因。考虑到要考虑的主题的多样性，组织者将通过在一系列场所发布公告和有针对性的电子邮件来确保不同的研究领域和观点得到充分的代表。术语“体验质量（QoE）”描述了用户对他或她使用某些应用程序的体验的主观评估。网络工程师过去一直关注服务质量：性能指标，如吞吐量、延迟和抖动、数据包丢失等。但是，由QoS参数衡量的不同性能只有在影响用户的后续体验时才有意义，因为他们试图通过网络使用一个或另一个应用程序。QoE损害（可能包括流视频的重新缓冲或真实的语音的过度往返延迟）对用户来说是真正重要的。研讨会的目标是了解关于QoE的研究状况，特别是考虑将正在进行的QoE研究线程整合到协作中的社区议程，以测量和分析当前互联网中的QoE状态，并识别和定位QoE损害的原因。这些会议将汇集不同领域的研究人员，这些领域对理解互联网中的QoE至关重要-从网络测量到实验设计和人为因素-并为跨领域研究和合作提供机会。讲习班的成果将开始界定宽带质量的相关衡量标准，并帮助网络供应商更好地了解全球互联网中出现缺陷的地方。这些结果反过来又会为互联网的典型用户带来更好的互联网体验。此外，研讨会的讨论旨在为网络，系统和人机交互社区提出新的研究合作。
