Quick User Datagram Protocol (UDP) Internet Connections (QUIC) is an experimental and low‐latency transport protocol proposed by Google, which is still being improved and specified in the Internet Engineering Task Force (IETF). The viewer's quality of experience (QoE) in HTTP adaptive streaming (HAS) applications may be improved with the help of QUIC's low‐latency, improved congestion control, and multiplexing features. We measured the streaming performance of QUIC on wireless and cellular networks in order to understand whether the problems that occur when running HTTP over TCP can be reduced by using HTTP over QUIC. The performance of QUIC was tested in the presence of network interface changes caused by the mobility of the viewer. We observed that QUIC resulted in quicker start of media streams, better streaming, and seeking experience, especially during the higher levels of congestion in the network and had a better performance than TCP when the viewer was mobile and switched between the wireless networks. Furthermore, we measured QUIC's performance in an emulated network that had a various amount of losses and delays to evaluate how QUIC's multiplexing feature would be beneficial for HAS applications. We compared the performance of HAS applications using multiplexing video streams with HTTP/1.1 over multiple TCP connections to HTTP/2 over one TCP connection and to QUIC over one UDP connection. To that effect, we observed that QUIC provided better performance than TCP on a network that had large delays. However, QUIC did not provide a significant improvement when the loss rate was large. Finally, we analyzed the performance of the congestion control mechanisms implemented by QUIC and TCP, and tested their ability to provide fairness among streaming clients. We found that QUIC always provided fairness among QUIC flows, but was not always fair to TCP.

协议游戏：QUIC准备好进行黄金时间流媒体播放了吗？
快速用户数据报协议（UDP）Internet连接（QUIC）是Google提出的实验性和低延迟传输协议，Internet工程任务组（IETF）仍在对其进行改进和指定。借助QUIC的低延迟，改进的拥塞控制和多路复用功能，可以改善HTTP自适应流（HAS）应用程序中查看者的体验质量（QoE）。我们测量了无线和蜂窝网络上QUIC的流传输性能，以了解通过使用HTTP over QUIC是否可以减少在TCP上运行HTTP时出现的问题。QUIC的性能已在由查看器的移动性引起的网络接口更改的存在下进行了测试。我们发现，QUIC可以更快地启动媒体流，更好地进行流传输并寻求体验，特别是在网络拥塞程度较高的情况下，并且当查看器处于移动状态并在无线网络之间切换时，其性能比TCP更好。此外，我们在具有各种损耗和延迟的仿真网络中测量了QUIC的性能，以评估QUIC的多路复用功能如何对HAS应用有利。我们比较了通过多个TCP连接上的HTTP / 1.1复用视频流，通过一个TCP连接的HTTP / 2和通过一个UDP连接的QUIC对HAS应用程序的性能进行比较。为此，我们观察到在具有较大延迟的网络上，QUIC提供的性能优于TCP。但是，当丢失率很大时，QUIC并没有提供明显的改进。最后，我们分析了QUIC和TCP实施的拥塞控制机制的性能，并测试了它们在流客户端之间提供公平性的能力。我们发现QUIC始终在QUIC流中提供公平性，但对TCP并不总是公平的。
