Title:
NETWORK BAND MEASUREMENT DEVICE, SYSTEM, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/043691
Kind Code:
A1
Abstract:
In order to compute an available band accurately and in a simple configuration in a network environment in which delay is irregularly caused, a transmitting side device generates a plurality of measurement packets of which the packet size is successively increased or decreased by a fixed number each time, includes in each measurement packet at least a packet number, a packet size, and a transmission time, to create a packet train, and transmits the packet train at predetermined equal intervals. A receiving side device, on the basis of a reception time and the transmission time of the received measurement packet, measures the time of arrival of each of the measurement packets constituting the packet train, and extracts as a valid packet a series of measurement packets at a location where a change in the measured time of arrival matches an arrival time change model having a predetermined pattern. In the arrival time change model indicated by the valid packet, a network available band is computed using a measurement packet, among a series of measurement packets having equal arrival times, that has a maximum packet size.
