Document Type and Number:
WIPO Patent Application WO/2023/148985
Kind Code:
A1
Abstract:
Provided are a band control device, a band control method, a band control program, and a network system that improve the reliability of a VPN. A measurement result holding unit (101) acquires and holds, for each combination of a transmission source and a transmission destination that communicate with each other via a WAN (400), the measurement values of a traffic volume transmitted to the WAN (400) and a traffic volume received by the transmission destination. For each combination, if a difference obtained by subtracting the received traffic volume from the transmitted traffic volume is equal to or greater than a threshold value, a control determination unit (102) restricts the transmitted traffic volume such that the restricted transmitted traffic volume falls within a restriction value that is constituted by the measurement value of the received traffic volume.
