Japanese Patent JP6680214
Kind Code:
B2
Abstract:
[Problem] To provide an available bandwidth measuring method capable of appropriately changing a search range of available bandwidths and improving the accuracy of available bandwidths. [Solution] The present invention is characterized by setting a first search range provided with a first determination section that determines whether or not the first search range for searching available bandwidths is to be changed to a second search range, generating a packet train containing a plurality of measurement packets having packet sizes that increase sequentially on the basis of the first search range, transmitting the plurality of measurement packets at a predetermined transmission interval, receiving the packet train and measuring a reception interval of the plurality of measurement packets, calculating and outputting estimated values of available bandwidths on the basis of the result of measuring the reception interval and packet sizes of the plurality of measurement packets, determining whether or not to change from the first search range to the second search range on the basis of the first determination section and the estimated values, and on the basis of the determination result, setting a change to the second search range and continuing the search for available bandwidths, or determining available bandwidths using the estimated values as available bandwidths.
