Prediction apparatus, communication control apparatus and prediction method

A communication control apparatus comprising:

• a memory;
• and
• a processor connected to the memory, the processor being configured to perform:
• classify communication traffic input during a predetermined period into a plurality of flows on a basis of a characteristic of the communication traffic;
• calculate a parallel-processable number that is a maximum number of pieces of prediction processing completable before a second period is reached in a case where the pieces of prediction processing of predicting a traffic amount in the second period after a first period are performed in parallel for the respective flows on a basis of the traffic amount for each of the flows in the first period and a predetermined condition;
• perform the prediction processing for a number of the flows within the parallel-processable number in a case where the number of flows classified is larger than the parallel-processable number;
• calculate a total of the traffic amounts in the second period on the basis of a result of the prediction processing;
• predict presence or absence of occurrence of congestion in the second period on a basis of a total value of the traffic amounts, and determine necessity of switching of a communication path on a basis of a prediction result;
• and
• issue a switching instruction to a switching apparatus that executes the switching of a communication path in a case where it is determined that the switching of a communication path is necessary.

A prediction method executed by a computer, the prediction method comprising:

• classifying communication traffic input during a predetermined period into a plurality of flows on a basis of a characteristic of the communication traffic;
• calculating a parallel-processable number that is a maximum number of pieces of prediction processing completable before a second period is reached in a case where the pieces of prediction processing of predicting a traffic amount in the second period after a first period are performed in parallel for the respective flows on a basis of the traffic amount for each of the flows in the first period and a predetermined condition;
• performing the prediction processing for a number of the flows within the parallel-processable number in a case where the number of flows classified is larger than the parallel-processable number;
• and
• calculating a total of the traffic amounts in the second period on the basis of a result of the prediction processing.
