Communication network device, communication network system, and method of communication network device

摘要

A traffic controller (8) receives, from a traffic monitor (7), a first control message generated in response to an increase in a total transmission rate of a plurality of packet flows sent from a plurality of wireless terminals (1) to a specific external network. The controller (8) determines, based on an evaluation criterion received from a criteria manager (6), one or more packet flows on which traffic shaping is to be imposed. In response to the first control message, the controller (8) controls a base station within a RAN (2) or a packet transfer node within a mobile backhaul (30) to execute the traffic shaping. This, for example, contribute to adjusting traffic that passes through a cellular communication network based on a monitoring result of a total transmission rate of traffic sent from the cellular communication network to the external network.
