Method and device for estimating a bandwidth

An electronic device, comprising:

• at least one processor;
• and
• a memory communicably connected with the at least one processor for storing instructions executable by the at least one processor, wherein execution of the instructions by the at least one processor causes the at least one processor to:
• receive a packet loss ratio estimation parameter transmitted by a receiver;
• calculate a packet loss ratio as a function of the packet loss ratio estimation parameter;
• determine whether the packet loss ratio is less than a preset packet loss ratio, and determine whether an estimated bandwidth obtained in advance from the receiver is more than a preset bandwidth and more than a current transmit bandwidth;
• and
• if the packet loss ratio is less than the preset packet loss ratio, and the estimated bandwidth is more than the preset bandwidth and more than the current transmit bandwidth, then determine a bandwidth in a bandwidth interval as a new current transmit bandwidth, wherein the bandwidth interval is more than a preset multiple of the current transmit bandwidth but no more than the estimated bandwidth, wherein the preset multiple is more than or equal to 1.08 times.

A non-transitory computer-readable storage medium storing executable instructions that, when executed by an electronic device with a touch-sensitive display, cause the electronic device to:

• receive a packet loss ratio estimation parameter transmitted by a receiver;
• calculate a packet loss ratio as a function of the packet loss ratio estimation parameter;
• determine whether the packet loss ratio is less than a preset packet loss ratio, and determine whether an estimated bandwidth obtained in advance from the receiver is more than a preset bandwidth and more than a current transmit bandwidth;
• and
• if the packet loss ratio is less than the preset packet loss ratio, and the estimated bandwidth is more than the preset bandwidth and more than the current transmit bandwidth, then determine a bandwidth in a bandwidth interval as a new current transmit bandwidth, wherein the bandwidth interval is more than a preset multiple of the current transmit bandwidth but no more than the estimated bandwidth, wherein the preset multiple is more than or equal to 1.08 times.
