  • Transmission device, method, and recording medium
    Patent number: 11528230
    Abstract: According to the present invention, in order to allow enhancement in the transmitting efficiency of a transmission system using link aggregation, if the bandwidth usage rates of the physical links constituting the LAG are imbalanced, identification information of a factor packet that serves as a factor for the imbalance is estimated on the basis of a distribution rule and the second information about a data amount. In addition, the factor packet is distributed to physical links to which the factor packet is distributed, and a packet that is not the factor packet is distributed according to the distribution rule, which is based on, for each of the physical links constituting the LAG, a remaining bandwidth obtained by subtracting the usage bandwidth of the factor packet distributed to said physical link from the maximum available bandwidth of said physical link.
