Abstract
Embodiments of the disclosure provide a method and apparatus for estimating a bandwidth. A transmitter receives an estimated bandwidth and a packet loss ratio estimation parameter; calculates a packet loss ratio as a function of the packet loss ratio estimation parameter; and determines whether the packet loss ratio is less than a preset packet loss ratio, and determines whether the estimated bandwidth is more than a preset bandwidth and more than a current transmit bandwidth; and if so, then the transmitter determines a bandwidth in a bandwidth interval as a new current transmit bandwidth, where the bandwidth interval is more than a preset multiple of the current transmit bandwidth but no more than the estimated bandwidth, where the preset multiple is more than or equal to 1.08 times.
