Abstract
Presented are methods and systems for providing bandwidth estimation and correction in a communications network. Bandwidth estimation and correction can include calculating a round trip time (RTT) value and a packet loss rate (PLR) value for each packet of a set of packets transmitted at different points in time from a server to a client terminal over the communications network; determining a bandwidth estimate based on the RTT and PLR values for the set of packets transmitted; determining a bandwidth measurement based on the RTT and PLR values for the set of packets; and determining a corrected bandwidth estimate based on the bandwidth estimate and the bandwidth measurement.
