1. A relay device used in an in-vehicle network including a plurality of function structures, the relay device comprising:
a relayer configured to perform a relay process for a frame transmitted and received between the function structures; and
a relay management processor, wherein
the relayer
receives, from a function structure, a target frame which is transmitted and received according to a predetermined communication protocol and includes information with which a request source of a service is identifiable and information with which a content of the requested service is identifiable, and
outputs the received target frame to the relay management processor, and the relay management processor
performs determination regarding setting change in the relay process of the relayer, on the basis of the information included in the target frame received from the relayer,
and
outputs the target frame to the relayer or discards the target frame, according to a result of the determination,
wherein upon determining that the setting change in the relay process is necessary, the relayer performs the setting change in the relay process according to determined content notified from the relay management processor, and
wherein on the basis of the information included in the target frame, the relay management processor specifies a communication band that is required in the relayer for preforming the relay process.
