Abstract
In this paper, we present the design, implementation, and evaluation
of iPlane, a scalable service providing accurate predictions of
Internet path performance for emerging overlay services. Unlike the
more common black box latency prediction techniques in use today,
iPlane adopts a structural approach and predicts end-to-end path
performance by composing the performance of measured segments of
Internet paths. For the paths we observed, this method allows us to
accurately and
efficiently predict latency, bandwidth, capacity and loss rates
between arbitrary Internet hosts. We demonstrate the feasibility and
utility of the iPlane service by applying it to several
representative overlay services in use today: content distribution,
swarming peer-to-peer filesharing, and voice-over-IP. In each case,
using iPlane's predictions leads to improved overlay
performance.
