<p>A relay device constituting an information processing system. An external information reception unit receives first external information transmitted from outside. An external information acquisition unit acquires second external information. According to the first and the second external information, an optical output control unit sets the optical output in the optical output unit to one of three or more output states. In the relay device, the external information reception unit receives a transmission origin identifier for identifying the transmission origin of the external information and external information. A transmission management information storage unit stores at least one set of a transmission destination identifier and transmission management information. A transmission destination identifier acquisition unit acquires a transmission destination identifier from the transmission management information storage unit. The external information transmission unit transmits external information to the transmission destination identified by the transmission destination identifier.</p> |
