摘要： The present invention provides for a method for reserving spare bandwidth for a link in a communication network including a plurality of links. The method provides for monitoring the volume of traffic routed through each link of the communication network. A single link failure for each link is then simulated and the volume of traffic which would be rerouted through each link for maintaining communication and the volume of traffic removed from each link are determined for each simulated single link failure. The difference between the volume of traffic which would need to be rerouted through each link and the corresponding volume of traffic removed from each link is then computed, and a maximum difference value is determined for each link for all simulated single link failures. An amount of spare bandwidth equivalent to the determined maximum difference is then reserved for each link.

摘要： An ring type optical LAN device includes a master node and a plurality of slave nodes that are interconnected by an optical fiber cable. A plurality of optical bypass transmission lines are provided in correspondence with each one of the slave nodes. Each of the optical bypass transmission lines bypasses the corresponding one of the slave nodes. Each slave node includes an E/O converter and an optical cutoff circuit. Each of the E/O converters is controlled to flash for generating an optical signal, which is transmitted to a network. When any one of the slave nodes fails such that the corresponding E/O converter is maintained in a turned on state, the associated optical cutoff circuit forcibly switches the E/O converter to a turned off state. This suppresses a network crash caused by the failure maintaining the E/O converter in the turned on state.

摘要： An optical communication network system is disclosed, which includes an optical switching apparatus. The optical switching apparatus includes an optical switch for switching and setting routes of an optical signal without being converted, a control unit for instructing the optical switch to execute a route switching operation, and a performance monitor for detecting performance of the optical signal having a route set by the optical switch. The performance monitor issues an alarm when the performance detected is deteriorated from predetermined performance. The control unit includes an alarm masking unit for masking the alarm issued from the performance monitor at least for a predetermined masking period from a starting time of a switching operation by the optical switch, and thus preventing the alarm from being issued.

摘要： An optical transmission network includes a first dispersion compensator arranged in a maximum dispersion span having a maximum dispersion value and searched out from within a maximum dispersion route having a maximum dispersion value from among routes of non-regeneration intervals within which a dispersion value before dispersion compensation does not satisfy an upper limit of a dispersion tolerance, and a second dispersion compensator arranged in a maximum dispersion span having a maximum dispersion value searched out from within a maximum dispersion route having a maximum dispersion value from among the routes when a dispersion compensator is successively arranged until a route of a non-regeneration interval within which a dispersion value of a certain channel does not satisfy the dispersion tolerance does not remain any more based on the dispersion value after the dispersion compensation with respect to the searched out maximum dispersion span. The dispersion compensation amounts of the first and second dispersion compensators are such that, when the dispersion compensation amount of the maximum dispersion span in which the first and second dispersion compensators are arranged is successively increased, the span has a residual dispersion value equal to or higher than a fixed range and the maximum dispersion route which relates to the spans has a residual dispersion value which satisfies the dispersion tolerance or the span has a residual dispersion value which is within the fixed range.

摘要： An optical transmission device improved in quality and reliability of OADM function and permitting configuration of highly-flexible, economical OADM networks. A wavelength tunable filter variably selects a wavelength according to a control frequency. A filter controller applies the control frequency to the filter while scanning wavelength over an entire signal bandwidth, to detect, from a reference wavelength monitor signal supplied thereto, a reference control frequency which permits the filter to select a reference wavelength and according to which wavelength is matched. On receiving a wavelength selection request, the controller obtains a target control frequency from the reference control frequency and the position of a target wavelength relative to the reference wavelength, and applies the obtained frequency to the filter. A reference wavelength filter transmits the reference wavelength therethrough. A light-receiving element monitors the transmitted reference wavelength to generate the monitor signal.
