1. A packet processing method performed by a packet processing device that receives packets sequentially from a transmission side device and transmits the packets to a receiving side device, comprising:

  • a response receiving step of receiving an acknowledgement that is transmitted from the receiving side device corresponding to the packets transmitted to the receiving side device;

    a round-trip delay time estimation step of estimating a time, which is taken until the acknowledgement corresponding to the packets is received from the receiving side device after the packets are transmitted to the receiving side device, as a round-trip delay time of the packets;

    a size determination step of determining a size of data that is divided into the packets and is continuously transmitted to the receiving side device even if the transmission side does not receive an acknowledgement;

    a transmission rate update step of updating a transmission rate of packets transmitted to the receiving side device according to the size of the data determined in the size determination step and the round-trip delay time estimated in the round-trip delay time estimation step; and

    a transmission step of transmitting the packets to the receiving side device at uniform time intervals and at the transmission rate updated in the transmission rate update step.
