Abstract
A data packet network comprises a policer module metering the flow and deciding whether arrived packets are to be transmitted or discarded. The flow of transmitted packets is metered by a sliding window procedure having a fixed window length. The sliding window is divided in a plurality of subwindows of equal length and the sliding window moves by steps corresponding to the length of the subwindows. For each subwindow and for the sliding window counts of transmitted and/or discarded bytes and/or packets are determined and stored. For an arrived packet the counts of the current subwindow are compared to a maximum value obtained from the counts of the sliding window and an absolute maximum value, and based on the result of the comparison, the policer module will transmit or discard the packet. The policer module can perform soft policing in the case where the packets belong to different traffic classes.
