Bandwidth estimation of a network connection
Aspects of the present disclosure describe an end-to-end communication protocol for interactive applications that ensure high throughput and low delay. A sender device and a receiver device are in communication with each other through a network. As multimedia content is captured by the sender device, the sender device packetizes each frame of the multimedia content into a plurality of packets thereby creating a packet train of packets that are sent to the receiver the device. The receiver device models the behavior of the network based on a continuous distribution. Based on the model of the network, the receiver device generates a forecast that describes the amount of data that the sender device can send to the receiver device. The receiver device sends the forecast to the sender device which subsequently sends data to the receiver device according to the forecast.
