An Information Plane for Internet Applications
University of Washington, 2008 - 127 pages
Over the last few years, several new applications have emerged on the Internet that are distributed at a scale previously unseen. Examples include peer-to-peer filesharing, content distribution networks, and voice-over-IP. This new class of distributed applications can make intelligent choices among the several paths available to them to optimize their performance. However, as a result of the best-effort packet forwarding interface exported by the Internet, applications need to explicitly measure the network to discover information about any path. Not only does measurement at the time of communication impose a significant overhead on most applications, but it is also redundant to have every application reimplement an Internet measurement component.
