Abstract:
1. A non-transitory computer-readable recording medium recording a program for measuring a band available for transmitting data to a measurement target device connected via a network, wherein the program causes a computer to execute: transmitting a first request having a first data size and requesting the measurement target device to return a first response having a fixed size from the measurement target device via the network to the band measuring device as well as for starting a first time measurement; terminating the first time measurement upon receipt of the first response from the measurement target device, and for determining a first time from when the first request is transmitted to when the first response is received; transmitting a second request having a second data size and requesting the measurement target device to return a second response having the fixed size, to the measurement target device via the network as well as for starting a second time measurement, wherein a processing time for the first request by the measurement target device is substantially the same as a processing time for the second request by the measurement target device; terminating the second time measurement upon receipt of the second response from the measurement target device, and for determining a second time from when the second request is transmitted to when the second response is received; and calculating a first communication band available for transmitting data to the measurement target device by dividing the difference between the first data size and the second data size by the difference between the first time and the second time.
