Methods and apparatus for estimating bandwidth of a data network
WO 2006058212 A3
Abstract
An inter-departure time of a pair of TCP segments, or a mean inter-departure time of a block of TCP segments, is determined and an inter-arrival time of a pair of non-duplicate acknowledgments is determined. The bandwidth of a data network may be estimated based at least in part on the inter-arrival time if the inter-arrival time is not less than the inter-departure time or the mean inter-departure time.
