Abstract
It is possible to reduce the memory capacity of a buffer of relay connection unit and reduce the time required for deciding a message to be transmitted. A relay connection unit is arranged between bushes to which electronic control units are connected and relays a message transmitted and received between the electronic control units belonging to different bushes. The relay connection unit includes: a buffer which temporarily stores message in the order to receptions; a storage unit which stores the priority set for each of the message; and a processing unit which extracts N message in the order of the receptions from the buffer, reads the priorities of the respective messages extracted from the storage unit, compares the priorities of the N messages, and transmits the message having the highest priority.
