Abstract

An apparatus includes a processor that monitors a first operational status of processors, activates one of unactivated processors of the processors, and based on a second operational status of the activated processor, determines an activation timing of a next processor to activate next, and activates the next processor at the activation timing.

Claims

1. A transmission apparatus comprising:

a processor that

monitors a first operational status of processors,

activates one of unactivated processors of the processors, and based on a second operational status of the activated processor, determines an activation timing of a next processor to activate next, and

activates the next processor at the activation timing.

2. The transmission apparatus according to claim 1, wherein

the activated processor receives a transmission signal, and executes received data processing, and

the processor determines the activation timing of the next processor based on a third operational status of the received data processing in the activated processor.

3. The transmission apparatus according to claim 2, wherein

the processor determines the activation timing of the next processor based on a completion of the data processing for chromatic dispersion compensation in the activated processor.

4. The transmission apparatus according to claim 3, wherein

the processor activates the next processor after a certain standby time elapses from the completion of the data processing for chromatic dispersion compensation in the activated processor.

5. The transmission apparatus according to claim 2, wherein

the activated processor executes data processing for adaptive equalization of the received data as the received data processing, and

the processor activates the next processor based on a completion of the data processing for adaptive equalization in the activated processor.

6. The transmission apparatus according to claim 2, wherein

the activated processor executes data processing for error correction of the received data as the received data processing, and

the processor activates the next processor based on a completion of the data processing for error correction in the activated processor.

7. The transmission apparatus according to claim 2, wherein

when the third operational status of the monitored activated processor after activation is a certain prescribed value or greater, the processor outputs an alarm regarding the data processing in the activated processor as a notification.

8. The transmission apparatus according to claim 1, further comprising:

a power consumption monitor that monitors a total power consumption of the processors as a whole, wherein

when the total power consumption is inside the certain prescribed range, the processor determines an activation timing of another processor to activate next, and activates the another processor at the activation timing.

9. The transmission apparatus according to claim 8, wherein

when a count of a number of times that the total power consumption is not contained inside a certain prescribed range exceeds a certain prescribed count, the processor outputs an alarm for indicating that the total power consumption of the processors as a whole is not contained inside a prescribed range as a notification.

10. The transmission apparatus according to claim 1, wherein

the transmission apparatus is expandable with multiple freely insertable and removable blades that additionally include one of the processors and an optical signal transceiver, and

the processor acquires information about the operational status of the data processing from each installed blade, determines the activation timing of each installed blade, and outputs a signal to each blade.

11. The transmission apparatus according to claim 1, wherein

the activated processor outputs information about state transitions include activating, processing, and processing complete to the processor as the operational status.

12. An electronic device comprising:

a processor that

monitors a first operational status of processors, provided inside the electronic device, that execute certain data processing,

activates one of unactivated processors of the processors, and based on a second operational status of the activated processor, determines an activation timing of a next processor to activate next, and

activates the next processor at the activation timing.

13. A method that executes processing repeatedly, comprising:

monitoring a first operational status of processors, provided inside an apparatus, that execute certain data processing with respect to a transmission signal,

activating one of unactivated processors of the processors, and based on a second operational status of the activated processor, determining an activation timing of a next processor to activate next, and

activating the next processor at the activation timing.
