Abstract
A trunk line topology network is configured with an electronic control units being communication apparatuses transmitting and receiving data, and gateway apparatuses and a distribution apparatus being a specific gateway apparatus that are connected to a communication line being a trunk line, for relaying, through the gateway apparatuses, data transmitted among the electronic control units. The distribution apparatus includes a storage region utilized for a database. The data transmitted from the electronic control units are relayed by the gateway apparatuses and then aggregated by the distribution apparatus. The relayed data are stored once on the database. When transmitting data to the electronic control units, the distribution apparatus reads out data from the database and transmits the data at the adjusted transmission timing. The gateway apparatuses relay the transmitted data.
