论文摘要
服务质量（QoS）指标涉及网络数量，例如延迟和损失，而经验质量（QOE）为最终用户体验提供了代理指标。文献中的许多论文提出了各种QoS指标和QoE之间的映射。本文进一步提供了QoE与带宽成本的分析。我们使用广泛接受的平均意见评分（MOS）等级来测量QoE。我们的结果自然表明，增加带宽会增加MOS。但是，我们通过使用TCP为Internet访问方案提供分析来扩展这种理解，并改变将TCP源的数量多路复用。对于这些目标方案，我们的分析表明，通过在带宽方面的进一步支出，您获得了什么MOS增加。我们预计这对于负责带宽购买和分配的商业组织将具有很大的价值。
Quality of Service (QoS) metrics deal with network quantities, e.g. latency and loss, whereas Quality of Experience (QoE) provides a proxy metric for end-user experience. Many papers in the literature have proposed mappings between various QoS metrics and QoE. This paper goes further in providing analysis for QoE versus bandwidth cost. We measure QoE using the widely accepted Mean Opinion Score (MOS) rating. Our results naturally show that increasing bandwidth increases MOS. However, we extend this understanding by providing analysis for internet access scenarios, using TCP, and varying the number of TCP sources multiplexed together. For these target scenarios our analysis indicates what MOS increase you get by further expenditure on bandwidth. We anticipate that this will be of considerable value to commercial organizations responsible for bandwidth purchase and allocation.
