  • Communication control device for selecting a path under different loads—high, middle, or low loads—based on whether a prohibition period has passed
    Patent number: 8914560
    Abstract: An IOP 14 includes a path-state determining unit 54 and a path selecting unit 55. The path-state determining unit 54 determines whether there is any path which is neither in process of data transmission nor in a prohibition period in which data transmission is prohibited for a predetermined time since the last data transmission has been completed out of multiple paths connecting a device to a communication partner device. When the path-state determining unit 54 determines that there is no path which is neither in process of data transmission nor in the prohibition period, the path selecting unit 55 selects a path which completes data transmission but does not pass through the prohibition period as a path for data transmission.
