在线服务都寻求为客户提供尽可能最佳的体验质量(QOE)。几毫秒的延迟可能会导致用户放弃猫视频或转到不同的购物网站，这会导致收入损失。因此，最大限度地减少用户和内容之间的延迟至关重要。为了减少延迟，内容和云提供商建立了大规模的全球网络。然而，他们的网络必须通过BGP与客户互联网服务提供商交互，而BGP没有性能概念。BGP的缺点很多，而且有很好的文档，但在本文中，我们要求社区退一步，重新思考我们对BGP的了解。我们考察了使用大型内容和云提供商网络进行的三项单独的性能研究，发现性能感知的路由方案很少能实现比BGP更低的延迟。我们展示了一张研究地图，以进一步研究击败BGP可能比之前想象的更困难的想法。
Online services all seek to provide their customers with the best Quality of Experience (QoE) possible. Milliseconds of delay can cause users to abandon a cat video or move onto a different shopping site, which translates into lost revenue. Thus, minimizing latency between users and content is crucial. To reduce latency, content and cloud providers have built massive, global networks. However, their networks must interact with customer ISPs via BGP, which has no concept of performance. The shortcomings of BGP are many and well documented, but in this paper we ask the community to take a step back and rethink what we know about BGP. We examine three separate studies of performance using large content and cloud provider networks and find that performance-aware routing schemes rarely achieve lower latency than BGP. We lay out a map for research to further study the idea that beating BGP may be more difficult than previously thought.
