A network (100), advantageously a home network, comprises a number of user devices (110), for example personal computers, game consoles and smartphones, each having an estimator application (111), preferably voluntarily installed by the user. The network (100) further comprises a network device (120) that acts as an interface between the network (100) and an external network. The estimator applications (111) measure (210) the network traffic for its user device (110), while the network device (120) in parallel generates (220) an independent measurement of the network consumption. The measurements are then compared (230). If the difference between the sum of the measurements from the estimator applications and the measurement of the network device is below a fixed threshold, it is assumed that the measurements are valid for the considered measurement time interval. Otherwise, the difference is an indication that at least one estimation was incorrect. |
