  • Communication Device, Storage Medium, Integrated Circuit, and Communication System
    Publication number: 20080008183
    Abstract: It is an object of the present invention to provide a QoS controllable communication device and communication system. A device 114 such as a first IP telephone comprising a QoS control unit 121 of the present invention transmits first transmission control data to a device 111 such as a PC performing lower priority communication. The first transmission control data includes data for changing the communication path of the lower priority communication, and the PC 111, having received the first transmission control data, performs subsequent lower priority communication through the first IP telephone or other device 114, enabling the first QoS control unit 121 to perform priority control. Because the present invention employs widely used protocols such as ARP and ICMP, the device 111 receiving the control data does not need protocols specific to the present invention.
