Abstract:
1. A policing device for transferring packets received from an input line to an output line, the device comprising: a monitoring unit that monitors a bandwidth of an input packet received from the input line for each of a plurality of packet flows; and a decision unit that performs a judgment of whether each input packet was received within a predetermined monitoring bandwidth assigned to the packet flow of the input packet, determines each input packet received within the monitoring bandwidth for the packet flow of the input packet as a conformance packet and each input packet received over the monitoring bandwidth for the packet flow of the input packet as a non-conformance packet, receives a command indicating allocation weights of a plurality of classes predefined for each packet flow from an external management terminal, stores the allocation weights in association with the classes for each packet flow, and judges whether each received input packet was received within a divisional bandwidth weighted with the allocation weight associated with a specific class of the packet flow to which the input packet belongs.
