Abstract
A relay device includes a plurality of physical ports (-to-N) that receive frames, and a layer-protocol processing unit () that transfers the frame received by one of the physical ports (-to-N) from at least one of the physical ports (-to-N). The layer-protocol processing unit () has a filtering function for blocking frames other than a clock-time synchronization frame during transfer involving a port selected from the plurality of physical ports (-to-N) as a port that relays only the clock-time synchronization frame used for synchronizing clock time.
