各种趋势正在重塑互联网上的内容交付：视频流量的爆炸性增长，用户对更高体验质量(QOE)的期望日益提高，以及来自各种来源(例如，云计算、内容提供商拥有的数据中心和运营商拥有的CDN)的服务器容量激增。为了满足用户提出的规模和质量要求，内容提供商已经开始使用中介将需求分散到各种CDN上。经纪人打破了许多传统的CDN假设(例如，意外的流量偏差、短时间内需求的显著差异等)。通过对一家领先的经纪商和一家领先的CDN的数据的分析，我们展示了经纪商在内容交付方面带来的潜在挑战和机遇。我们通过重新设计的Broker-CDN接口迈出了改进的第一步。
Various trends are reshaping content delivery on the Internet: the explosive growth of traffic due to video, users' increasing expectations for higher quality of experience (QoE), and the proliferation of server capacity from a variety of sources (e.g., cloud computing, content provider-owned datacenters, and ISP-owned CDNs). In order to meet the scale and quality demands imposed by users, content providers have started to spread demand across a variety of CDNs using a broker. Brokers break many traditional CDN assumptions (e.g., unexpected traffic skew, significant variance in demand over short timescales, etc.). Through an analysis of data from a leading broker and a leading CDN, we show the potential challenges and opportunities that brokers impart on content delivery. We take the first steps towards improvement through a redesigned broker-CDN interface.
