10. A high-speed communication method in a high-speed communication system performed via a plurality of nodes on a communication path including a start point node, an end point node, and a relay node disposed between the start point node and the end point node, the method comprising:
-
transmitting to the end point node a control start signal announcing that communication is to be performed, by the start point node; calculating performance model information of the end point node based on detection of the control start signal, by the end point node that has detected the control start signal; calculating performance model information of the relay node based on the detection of the control start signal, by the relay node; transmitting a performance model notice signal storing the performance model information to the end point node, by the start point node; comparing the performance model information stored in the performance model notice signal with performance model information calculated by the relay node and transferring the performance model notice signal storing only the performance model information representing a smaller value when the relay node transfers the performance model communication signal to the end point node; storing the performance model information stored in the received performance model notice signal and transmitting a performance model decision signal storing the performance model information to the start point node, by the end point node; storing the performance model information stored in the performance model decision signal, in the relay node that has relayed the performance model decision signal to the start point node and in the start point node; and performing TCP control based on the performance model information stored in the performance model decision signal, by the start point node and the relay node.
