Abstract: In a case where a failure occurs in a part of an optical fiber in an optical cable, when attempting to switch to a redundant configuration, the stable use of an optical transmission system is impaired, so that the wavelength band cannot be used effectively. Accordingly, the optical transmission system of the present invention includes a first optical device configured to change the transmission line of a wavelength band signal propagating through a first optical transmission line to a second optical transmission line that is the same path as the first optical transmission line, in the stage before a faulty part in the first optical transmission line, and a second optical device configured to change the transmission line of the wavelength band signal from the second optical transmission line to the first optical transmission line, in the stage after the faulty part.

Abstract: In a processing apparatus, a determination unit determines whether a jump destination address of a jump instruction in a process execution program being executed corresponds to a sensitive address region. When the determination unit determines that the jump destination address does not correspond to the sensitive address region, the security control unit executes control to allow the execution of the jump instruction and record a jump source address and the jump destination address of the jump instruction in jump history information as a jump execution record. When it is determined that the jump destination address corresponds to the sensitive address region, the security control unit searches for a “suspicious record” in the jump history information. The suspicious record is a jump execution record corresponding to an “unusual jump destination address”.
