论文摘要
这封信分析了最佳富度链接的低延迟区域（LLR）（即没有流量差异，并且首先是首次服务时间表），均带有延迟敏感（DS）流媒体和非固定敏感（NDS）背景流量。此外，在LLR内部，我们表明它存在DS和NDS流量流的比例公平到达率分配。该最佳操作点是由考虑NDS流量负载以及DS数据包的平均延迟的简单吞吐量折衷而导致的。为了展示在现实情况下如何使用所提出的权衡来分配NDS流量，我们使用Google STADIA流量痕迹来生成DS流量。此用例的结果证实，无论数据包到达和数据包服务时间的分布如何，吞吐量 - 折衷的权衡也有效。
This letter analyzes the Low-latency Region (LLR) of a best-effort link (i.e., no traffic differentiation, and first come first serve scheduling) carrying both delay-sensitive (DS) streaming and non-delay-sensitive (NDS) background traffic. Moreover, inside the LLR, we show it exists a proportional fair arrival rate allocation for both the DS and NDS traffic streams. This optimal operating point results from maximizing a simple throughput-delay trade-off that considers the NDS traffic load, and the mean delay of the DS packets. To show how the presented trade-off could be used to allocate NDS traffic in a realistic scenario, we use Google Stadia traffic traces to generate the DS flow. Results from this use-case confirm that the throughput-delay trade-off also works regardless the distribution of the packet arrival and packet service times.
