论文摘要
在过去的几年中，我们目睹了对行业和学术界的多路径用例中的利益越来越多。例如，阿里巴巴（Alibaba）在TAOBAO简短视频中部署了Qoe驱动的多路径Quic解决方案Xlink，并显示出减少尾巴潜伏期和视频重新阻碍的好处。目前，多路径QUIC协议正在IETF Quic工作组的标准化过程中，该草案最近已更新为版本02。该草案的重点是为实施提供基本指导，以便我们鼓励更多的探索，测试，最后是加速采用这项技术。但是，Draft-02提出了一个公开问题，即是否应使用单数据包号空间（SPN）或多个数据包号空间（MPN）（如当前的草稿）共存。知道没有实验就无法得出一个可靠的结论，我们在阿里巴巴实施了SPN和MPN，并测量了他们的绩效。目的是帮助社区更好地理解这种含义，我们希望该报告对有兴趣部署多路的工程师和研究人员可以成为有用的资源。
Over the past few of years, we have witnessed increasing interests in the use cases of multi-path QUIC from both industry and academia. For example, Alibaba deployed XLINK, a QoE-driven multi-path QUIC solution, in Taobao short video and showed benefits in both reduced tail latency and video re-buffering. For the time being, the multi-path QUIC protocol is in the process of standardization at the IETF QUIC working group, with the draft recently updated to version 02. The focus of the draft is to provide basic guidance on the implementation so that we can encourage more exploration, testing, and finally, an accelerated adoption of this technology. However, draft-02 has brought up an open issue on whether the multi-path QUIC should be implemented using single packet number space (SPNS) or multiple packet number space (MPNS), as in the current draft, both options co-exist. Knowing that one cannot draw a solid conclusion without experiments, we implement both SPNS and MPNS at Alibaba and measured their performance. The goal is to help the community better understand the implication, and we hope this report can be a useful resource for engineers and researchers who are interested in deploying multi-path QUIC.
