论文摘要
无线网络变得越来越复杂，人满为患，在当今的互联网中对端到端网络流造成了最延迟，抖动和吞吐量损害。因此，我们主张基于精细的移动端点无线测量值，以通过明确定义的API到移动的无线物理层来告知精确的拥塞控制算法。我们提出的拥塞控制算法基于在端点（PBE-CC）进行的物理层带宽测量值，并捕获了最新的5G新无线电创新，这些创新增加了无线容量，但突然的无线容量却降低了无线功能，PBE-CC sender可以做出非常快速和非常快速的反应。我们在软件定义的无线电上实施了PBE测量模块的概念验证原型，以及PBE发件人和接收器在C中进行了广泛的绩效评估，将PBE-CC与领先的细胞感知和无线通讯和无线充血的控制协议相比，在研究社区中提出的，在移动和整体的移动场景中，在移动和忙碌的网络中，繁忙和安静。结果显示，平均吞吐量比BBR高出6.3％，同时将95％的延迟减少了1.8倍。
Wireless networks are becoming ever more sophisticated and overcrowded, imposing the most delay, jitter, and throughput damage to end-to-end network flows in today's internet. We therefore argue for fine-grained mobile endpoint-based wireless measurements to inform a precise congestion control algorithm through a well-defined API to the mobile's wireless physical layer. Our proposed congestion control algorithm is based on Physical-Layer Bandwidth measurements taken at the Endpoint (PBE-CC), and captures the latest 5G New Radio innovations that increase wireless capacity, yet create abrupt rises and falls in available wireless capacity that the PBE-CC sender can react to precisely and very rapidly. We implement a proof-of-concept prototype of the PBE measurement module on software-defined radios and the PBE sender and receiver in C. An extensive performance evaluation compares PBE-CC head to head against the leading cellular-aware and wireless-oblivious congestion control protocols proposed in the research community and in deployment, in mobile and static mobile scenarios, and over busy and quiet networks. Results show 6.3% higher average throughput than BBR, while simultaneously reducing 95th percentile delay by 1.8x.
