速度估计方法、速度估计设备、速度估计系统以及速度估计设备的控制程序的记录介质
Abstract:
为了能够判断传输速率的测量结果的有效性，一种速度估计方法向作为传输速率测量目标的被测区间发送数据包和在该数据包之前和之后的探测包，基于作为紧接着数据包之前和之后通过被测区间发送的探测包之间的接收时间间隔的第一接收时间间隔和数据包的数据量，估计该被测区间的传输速率，并通过将作为在被测区间中在探测包之间不存在数据包的状态下连续通过了该被测区间的探测包之间的接收时间间隔的第二接收时间间隔与第一接收时间间隔进行比较，来判断传输速率的有效性。
Abstract(English):

In order to enable the determination of the validity of measurement results of transmission speed, the disclosed speed estimation method: transmits a data packet and a probe packet therebefore and thereafter in an interval for measurement that is the subject of transmission speed measurement; estimates the transmission speed of the interval for measurement on the basis of the amount of data of the data packet and a first reception gap, which is the gap between the reception of the probe packets transmitted through the interval for measurement immediately before and immediately after the data packet; and determines the validity of the transmission speed by comparing the first reception gap and a second reception gap which is the gap between the reception of probe packets successively passed through the interval for measurement in the state of no data packet being present therebetween in the interval for measurement.
