We have developed iPlane, an Internet-wide information plane that provides real-time predictions of approximate paths and path properties between arbitrary end-hosts. iPlane continually performs measurements from several hundred geographically distributed vantage points to build a map of the Internet's structure and to annotate links in this map with performance metrics such as latency, loss rate, and bandwidth capacity. We have evaluated the utility of iPlane by applying it to several popular distributed services in use today: content distribution, swarming peer-to-peer file-sharing, and voice-over-IP. In each case, using iPlane's predictions leads to improved application performance.
