Abrégé
(EN)
A network interface device is provided. The network interface device comprises an input configured to receive a data frame from a network. The network interface device also comprises a timing component configured to store, for the data frame, first timing information and compensation information. The compensation information is specific to the frame. The first timing information and said compensation information representing a time when the data frame was received.
