Evaluation device, evaluation method and recording medium
First Claim
1. An evaluation device, comprising:
- a communication interface configured to communicate with a control device which is connected to a network that includes at least one transfer device and to receive, from the control device, records used for transmission control of data currently circulating in the network; and
processing circuitry configured to implementa first evaluator configured, for each of the records, to evaluate extent of variation of an amount of the data, based on a history of the amounts of the data matching a condition of the record;
a second evaluator configured, for each of the records, to evaluate a size of a space represented by the record, based on the condition of the record; and
a calculator configured, for each of the records, to calculate an index value representing a possibility that the respective record corresponds to a future spike flow at a future time when a predetermined or a greater amount of the data matches the condition of the record within a fixed period of time, based on an evaluation result by the first evaluator, and an evaluation result by the second evaluator,wherein the processing circuitry is configured to control an output of an indication of a possibility that one of the records corresponds to a future spike flow based on the calculated index values for each of the records.

Abstract
An evaluation device includes a first evaluator configured, for each record used for transmission control of data circulating in a network, to evaluate extent of variation of an amount of the data, based on a history of the amounts of the data matching a condition of the record; a second evaluator configured, for each of the records, to evaluate a size of a space represented by the record, based on the condition of the record; and a calculator configured, for each of the records, to calculate an index value representing a possibility that a predetermined or a greater amount of the data matches the condition of the record within a fixed period of time, based on an evaluation result by the first evaluator, and an evaluation result by the second evaluator. Therefore, it is possible to evaluate a possibility of a sudden occurrence of a flow whose traffic volume is large.

6. An evaluation method executed by a computer, the method comprising:
-
communicating with a control device which is connected to a network that includes at least one transfer device and receiving, from the control device, records used for transmission control of data currently circulating in the network; a first evaluation step, for each of the records, evaluating extent of variation of an amount of the data, based on a history of the amounts of the data matching a condition of the record; a second evaluation step, for each of the records, evaluating a size of a space represented by the record, based on the condition of the record; and a calculation step, for each of the records, calculating an index value representing a possibility that the respective record corresponds to a future spike flow at a future time when a predetermined or a greater amount of the data matches the condition of the record within a fixed period of time, based on an evaluation result by the first evaluation step, and an evaluation result by the second evaluation step; and controlling an output of an indication of a possibility that one of the records corresponds to a future spike flow based on the calculated index values for each of the records.
