Abstract
There is provided an information processing system capable of suppressing arising of unprocessed data and depreciation of data with the lapse of time. The information processing system (1) includes a buffer unit (5), a processing unit (6), and a control unit (9). The buffer unit (5) sequentially receives data acquired by an observation terminal (2) from the observation terminal (2). The processing unit (6) sequentially processes the data received by the buffer unit (5). The control unit (9) controls an index value indicating information freshness by adjusting a resource of processing of the processing unit (6). The index value indicating the information freshness is calculated based on elapsed time from the time when the data is acquired by the observation terminal (2).
Claims8
An information processing system comprising:
- circuitry
- to sequentially receive data acquired by an observation terminal from the observation terminal;
- to sequentially process the received data;
- and
- to control an index value indicating information freshness by adjusting a resource for processing the received data, the index value being calculated based on elapsed time from a time when the data is acquired by the observation terminal, wherein
- the circuitry calculates an acquisition rate of the data by the observation terminal and a service rate of the processing, and
- the circuitry controls the service rate by adjusting the resource for the processing the received data so that, when a relation between a utilization rate for which the acquisition rate is divided by the service rate and the index value is predetermined by a queueing model, the utilization rate obtained from the acquisition rate and the calculated service rate becomes a utilization rate corresponding to a target value of the index value predetermined based on the acquisition rate and the queueing model.
An information processing method comprising:
- sequentially receiving data acquired by an observation terminal from the observation terminal;
- sequentially processing the received data;
- calculating an index value indicating information freshness, the calculating being performed based on relapsed time from a time when the data is acquired by the observation terminal;
- controlling the index value by adjusting a resource for processing the received data;
- calculating an acquisition rate of the data by the observation terminal and a service rate of the processing;
- and
- controlling the service rate by adjusting the resource for processing the received data so that, when a relation between a utilization rate for which the acquisition rate is divided by the service rate and the index value is predetermined by a queueing model, the utilization rate obtained from the acquisition rate and the calculated service rate becomes a utilization rate corresponding to a target value of the index value predetermined based on the acquisition rate and the queueing model.
