Control apparatus, communication system, control method and program
A control device includes an acquisition unit that acquires information from a distributed station that notifies the information related to one or more events occurred within a predetermined time period at a predetermined notification frequency, an information analysis unit that executes analysis processing on the information, a frequency derivation unit that derives an occurrence frequency of the information, a load derivation unit that derives a load of analysis processing of the information, and a frequency control unit that controls the predetermined notification frequency with a frequency lower than the occurrence frequency as an upper limit on the basis of at least one of an analysis result of the information, an occurrence frequency of the information, and a load of analysis processing of the information.
1 . A control device comprising:
an acquisitor configured to acquire information used for judging a wavelength switching to an optical path, from a distributed station that notifies the information related to one or more events occurred within a predetermined time period at a predetermined notification frequency;
an information analyser configured to execute analysis processing on the information;
a frequency derivator configured to derive an occurrence frequency of the information;
a load derivator configured to derive a load of analysis processing of the information;
a frequency controller configured to control the predetermined notification frequency with a frequency lower than the occurrence frequency as an upper limit on the basis of an occurrence frequency of the information;
a storage processor configured to record the information notified from the distributed station in a storage in association with the notification time, and discard the information from the storage when it is judged that the occurrence frequency of the information is less than a predetermined threshold value.
2 . A communication system comprising a distributed station and a control device, wherein
the distributed station comprises a notification processor that notifies information related to one or more events occurred within a predetermined time period at a predetermined notification frequency, and
