Abstract
A storage medium having a program that executes a process including acquiring a packet formed by dividing data to be transmitted to receiving apparatus by transmitting apparatus and a packet that includes an ACK number to identify an amount of the data about which reception of packets transmitted from the transmitting apparatus to the receiving apparatus by the receiving apparatus has been confirmed; when the acquired packet is a retransmission packet and a lost packet corresponding to the retransmission packet has not been acquired, classifying a position of the lost packet as any of a last packet, an intermediate packet, and a leading packet by comparing the ACK number included in the retransmission packet and the ACK number included in each of packets previous and subsequent to the lost packet; and calculating a retransmission time by a calculation method identified based on the classified position of the lost packet.
