我们检查了用户网络性能的当前状态以及从全球内容提供商Facebook的有利位置改进它的机会。 Facebook使用流行音乐网络和互连网络为世界各地分发的20亿多个用户提供服务。在本文中，我们在全球所有Facebook的POPS上对TCP和HTTP层进行了一项大规模的，为期10天的测量研究，用于生产用户流量，收集了数百万亿个采样的HTTP Sessions的绩效测量。我们讨论了收集和分析测量结果的方法，包括一种新颖的方法来表征从服务器端可实现的征用的用户。我们发现大多数用户会议的MinRTT小于39ms，并且可以支持高清视频。我们调查是否可以通过将绩效信息纳入Facebook的路由决策来提高性能；我们发现Facebook默认路由在很大程度上是最佳的。据我们所知，我们的测量研究是从全球内容提供商的有利位置从当今互联网上用户性能的第一个表征。
We examine the current state of user network performance and opportunities to improve it from the vantage point of Facebook, a global content provider. Facebook serves over 2 billion users distributed around the world using a network of PoPs and interconnections spread across 6 continents. In this paper, we execute a large-scale, 10-day measurement study of metrics at the TCP and HTTP layers for production user traffic at all of Facebook's PoPs worldwide, collecting performance measurements for hundreds of trillions of sampled HTTP sessions. We discuss our approach to collecting and analyzing measurements, including a novel approach to characterizing user achievable goodput from the server side. We find that most user sessions have MinRTT less than 39ms and can support HD video. We investigate if it is possible to improve performance by incorporating performance information into Facebook's routing decisions; we find that default routing by Facebook is largely optimal. To our knowledge, our measurement study is the first characterization of user performance on today's Internet from the vantage point of a global content provider.
