Patent ID: 8711726

Claim:
A method of estimating traffic consumption during a period of time of a first network comprising an interface device connecting the first network to an external network and at least one user device having an application configured to measure traffic consumption of the at least one user device during the period of time, wherein the measured traffic involves a device in the external network, the method comprising the steps, in the device, of: obtaining a sum of the measurements of the traffic consumption during the period of time for the at least one user device; obtaining a global measurement of traffic consumption during the period of time; and determining that the estimations are correct in case a difference between the sum and the global measurement is below a threshold value; wherein the measurements of traffic consumption are of at least one of: traffic delivered to the at least one user device and traffic delivered to the first network, respectively, and traffic sent from the at least one user device and traffic sent from the first network, respectively.
