EDGE NODE AND BAND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To keep high throughput while efficiently utilizing a guaranteed band even when a target flow of band control is multiplexed in data transfer in a band guaranteed network.

SOLUTION: A band information storing section stores a guaranteed band allocated to a service target flow in the band guaranteed network. A propagation delay time calculating section measures the propagation delay time of the service target flow. A window size calculating section calculates a window size in which the data of the service target flow is a band within the guaranteed band from the guaranteed band of the service target flow and the propagation delay time of the service target flow. An ACK scheduling section schedules the timing of transmitting an ACK packet of the service target flow to be transmitted to a data transmission terminal on the basis of the propagation delay time and the window size. An advertisement window size writing section writes the window size into the ACK packet.
