Abstract

A monitoring device 1 includes an individual alarm reception unit 10 configured to receive individual alarms issued from a plurality of devices constituting an optical transmission network, a table 20 in which a search operator for searching for necessary information, that is information required for treating the individual alarms in the same manner when specifications of the individual alarms are different from each other, is associated with information included in the individual alarms, a search operator extraction unit 30 configured to extract the search operator using the information included in each of the individual alarms as a key, a rule 40 in which the search operator is associated with the necessary information; and a unified alarm information generation unit 50 configured to search the rule 40 using the search operator as a key, compare the information included in the individual alarms with the necessary information corresponding to the search operator, and add information, that is included in the necessary information but not included in the individual alarm, to the individual alarm to generate unified alarm information.

First claim

The invention claimed is:

1. A monitoring device comprising:
an individual alarm reception unit, including one or more processors, configured to receive individual alarms issued from a plurality of devices constituting an optical transmission network;
a table in which a search operator for searching for necessary information required for treating the individual alarms in a same manner when specifications of the individual alarms are different from each other, is associated with information included in the individual alarms;
a search operator extraction unit, including one or more processors, configured to extract the search operator using the information included in each of the individual alarms as a key;
a rule in which the search operator is associated with the necessary information; and
a unified alarm information generation unit, including one or more processors, configured to search the rule using the search operator as a key, compare the information included in the individual alarms with the necessary information described in the searched rule, and add information, that is included in the necessary information but not included in the individual alarms, to the individual alarms to generate unified alarm information.

2. The monitoring device according to claim 1 , wherein the table includes a condition for extracting the search operator, and
the search operator extraction unit extracts the search operator when a condition included in the individual alarms matches the condition included in the table.

3. The monitoring device according to claim 1 , further comprising:
an individual alarm suppression unit, including one or more processors, configured to transmit, when predetermined unified alarm information is issued, an individual alarm inhibition signal for inhibiting issuance of subsequent individual alarms to the plurality of devices constituting the optical transmission network.

4. A monitoring method executed by a monitoring device for monitoring an optical transmission network, the monitoring method comprising:
receiving individual alarms issued from a plurality of devices constituting the optical transmission network;
searching, using information included in each of the individual alarms as a key, a table in which a search operator for searching for necessary information required for treating the individual alarms in a same manner when specifications of the individual alarms are different from each other, is associated with the information included in the individual alarms, thereby extracting the search operator;
searching, using the search operator as a key, a rule in which the search operator is associated with the necessary information; and
comparing the information included in the individual alarms with the necessary information described in the searched rule, and adding information, that is included in the necessary information but not included in the individual alarms, to the individual alarms to generate unified alarm information.

5. The monitoring method according to claim 4 , wherein the table includes a condition for extracting the search operator, and
wherein extracting the search operator comprises extracting the search operator when a condition included in the individual alarms matches the condition included in the table.

6. The monitoring method according to claim 4 , further comprising:
when predetermined unified alarm information is issued, transmitting an individual alarm inhibition signal for inhibiting issuance of subsequent individual alarms to the plurality of devices constituting the optical transmission network.
