Abstract:
1. A communication device connected to a network, said communication device comprising: a relay device information obtaining unit configured to communicate predetermined data with relay devices on a data transmission network path, and obtain, based on a result of the communication of the predetermined data, self-device transmission status information that is information indicating a transmission status of said communication device; a neighboring communication device determining unit configured to determine, from other communication devices connected to the network, neighboring communication devices from each of which another-device transmission status information that is information indicating a transmission status of a corresponding one of the other communication devices is to be obtained; a neighboring communication device information obtaining unit configured to obtain the another-device transmission status information from each of the neighboring communication devices; a transmission rate control information correcting unit configured to generate, as corrected transmission status information, (i) a corrected self-device round-trip time generated by using, as a round-trip time correction amount, an average of differences each between the self-device round-trip time and an another-device round-trip time to a self-device round-trip time and (ii) a corrected self-device frame loss rate generated by using, as a frame loss rate correction amount, an average of differences each between the self-device frame loss rate and an another-device frame loss rate to a self-device frame loss rate, the self-device round-trip time and the self-device frame loss rate each being an information item included in the self-device transmission status information, and the another-device round-trip time and the another-device frame loss rate each being an information item included in the another-device transmission status information; a transmission rate determining unit configured to determine a transmission rate of data to be transmitted, based on the corrected transmission status information; and a data transmission unit configured to transmit the data according to the determined transmission rate.
