There is provided a communication status measurement device wirelessly connected to a public network and communicating with a server connected to the public network through a communication channel determined in advance. A measurement unit repeatedly measures a time since a dummy packet is transmitted to the server until an acknowledgement packet corresponding to the dummy packet is received. A pattern calculation unit calculates a pattern obtained by removing a component at frequencies more than a first frequency from a pattern of variations in a measured value. An RTT acquisition unit that acquires a round trip time, which is used to calculate an actual bandwidth of the communication channel, on a basis of the calculated pattern. An implementation unit implements a virtual private network in the communication status measurement device itself.

An information terminalB receives plural UDP packets each having a predetermined data size and sequentially transmitted at a predetermined time interval in a predetermined order; extracts pairs of the UDP packets, in which each of a transmission order and a reception order is continuous and the transmission order and the reception order match with each other, from among the received UDP packets; calculates an evaluation value for evaluation of a delay state of a communication path between an information terminalA and the information terminalB based on comparison between a reception time interval of the packets in each of the extracted pairs of the UDP packets and the predetermined time interval; and judges whether a bit rate of the UDP packets is available or unavailable based on comparison between the calculated evaluation value and a threshold.

An information terminal sequentially transmits one or more packets to an information distribution server, receives acknowledgments for the transmitted packets from the information distribution server, and records a round trip time and occurrence of packet loss for each of the transmitted packets. Among one or more packet sequences, the information terminal counts the number of packet sequences which are such that the number of packet losses included in each of the packet sequences and an increase state of the round trip time for packets included in the packet sequence satisfy respective predetermined conditions. Each of the one or more packet sequences has multiple continuous packets including one or more packets, for which packet loss is recorded among the transmitted packets, at the top. The information terminal calculates a packet loss ratio on the basis of the counted number and the number of transmitted packets.

A mobile terminal obtains a measurement value of a round-trip time in a communication channel used for communication with a server and a measurement value of a packet loss ratio in the communication channel (Sand S). Then, the mobile terminal determines whether or not a retransmission timeout is occurring in the server (S, S, and S). If a retransmission timeout is occurring in the server, the mobile terminal calculates an estimate value of the bandwidth in the communication channel by using a special throughput equation including a timeout time (S). On the other hand, if a retransmission timeout is not occurring in the server, the mobile terminal calculates an estimate value of the bandwidth by using a normal throughput equation which does not include a timeout time.
