Abstract: Provided are a method and a system for transmitting multiple data, in which the method includes receiving a plurality of transmission files for transmission from a transmission device of the first network to a reception device of the second network, and temporarily storing the received files, generating flexible packets by dividing each of the plurality of transmission files by a flexible packet length determined according to size of the files, in which a transmission file in a size smaller than the flexible packet length among the plurality of transmission files is generated as one flexible packet without being divided, loading the flexible packets into a plurality of flexible frames based on a corresponding transmission file priority according to a maximum data transmission size, and transmitting the plurality of flexible frames to the second network.
