PROBLEM TO BE SOLVED: To provide an information transmission system that allows even an on-vehicle device with low transmission processing performance to avoid missing out packets by applying general purpose techniques such as an Ethernet hub in order to avoid the occurrence of missing out packets in the on-vehicle device with low transmission processing performance due to increase in the number of packets to be processed per unit time if the number of communication partner on-vehicle devices is large or data with a short transmission period is large.SOLUTION: An information transmission device is connected to a relay device, receives data relayed by the relay device, combines and consolidates the received multiple pieces of special data into one piece or smaller pieces of data than the number of pieces of the received special data, and adds destination information to the consolidated data and transmits the result to the relay device. The relay device relays the consolidated data on the basis of the added destination information. |
