PROBLEM TO BE SOLVED: To provide a relay device and a message relay method, capable of suppressing the reduction of a message arrival factor and the increase of a message transmission delay if communication network traffic increases.SOLUTION: On receiving a message that includes a message element of which priority is given in advance, the relay device compares a necessary bandwidth which is necessary for transferring the message with an idle bandwidth of a communication channel to be a transfer destination of the message. If the necessary bandwidth is larger than the idle bandwidth, the relay device successively deletes from a message element having the lowest priority to the largest, until the necessary bandwidth becomes smaller than the idle bandwidth or until there is no message element that can be deleted in the message. The message after the processing is transmitted to the communication channel to be the transfer destination. |
