摘要： A scale-out of a gateway server is realized according to a rapid increase in communication volume, without incurring system down. A high-quality communication is provided to priority users even during scaling out the gateway server. A high-quality communication is continuously provided to priority users without incurring the system down even if the scale-out/in of the gateway server is repeated. A bandwidth control apparatus transmits packets to plural virtual nodes equipped in a server device, reads the packets from any high priority queue and any low priority queue which are associated with the subject apparatus, and limits the packets to an upper limit bandwidth determined for each of the virtual nodes, and changes association of the high priority queues and the low priority queues with the virtual node bandwidth limiters according to an instruction from the control server for determining the scale-out/in of the virtual node.

摘要： A congestion control target call is selected so as to be capable of reducing inequality or the like between services or users in consideration of characteristics such as the urgency of the service or the user. A communication system includes a server device, a terminal device which transmits and receives a packet to and from the server device, and a communication device which relays communication of a packet with the terminal device and a control method thereof. The communication device selects a call which is a congestion control target on the basis of a value indicating a priority selected as a congestion control target and/or a bandwidth or a packet communication traffic volume occupied by a service or user when congestion occurs in consideration of characteristics such as the urgency of the service or the user when the congestion of the communication system is detected or foreseen.
