The path taken by a packet traveling across the Internet depends on a large number of factors, including routing protocols and per-network routing policies. The impact of these factors on the end-to-end performance experienced by users is poorly understood. In this paper, we conduct a measurement-based study comparing the performance seen using the(More)
Despite its obvious success, robustness, and scalability, the Internet suffers from a number of end-to-end performance and availability problems. In this paper, we attempt to quantify the Internet's inefficiencies and then we argue that Internet behavior can be improved by spreading intelligent routers at key access and interchange points to actively manage(More)
In spite of much research effort, there is no universally applicable software reliability growth model which can be trusted to give accurate predictions of reliability in all circumstances. Worse, we are not even in a position to be able to decide a priori which of the many models is most suitable in a particular context. Our own recent work has tried to(More)
By any metric, the Internet has scaled remarkably—from four nodes in 1969 to an estimated 40 million hosts today. This reflects a sustained growth rate over three decades of more than 80% per year, during continuous service. In system growth, the Internet has been matched only by the major infrastructure projects of the early 1900s: the electric power grid,(More)
