As the need increases for fast transfers of large amounts of data over the Internet, it is increasingly important to have an accurate estimation of throughput between two sources. This is the primary goal of the Bandwidth Estimation Project, which is part of the US Department of Energy's Scientific Discovery through Advanced Computing program. It is developing new algorithms and techniques to allow for the fastest communication possible. The project proposal given on this Web site gives a detailed overview of the research being done. Some papers and presentations can be downloaded, including several from a June 2002 meeting at the San Diego Supercomputing Center.
