Abstract
The technology in this application determines the throughput over a data communication substantially as experienced by a user receiving the data. The determined throughput is substantially independent of the total amount of data transferred over the connection. This “active” throughput measure is divided into two parts to provide two performance measures: transfer throughput and latency. Latency corresponds to a time period needed to accomplish one or more functions associated with the data connection, like setting up and taking down the connection, during which payload type data to be transferred to an end user is not transferred. By identifying and removing the initial latency from the throughput determination for the data connection, the determined transfer throughput provides a more accurate measure of the throughput actually experienced by the end user.
