Communication management apparatus and communication management method

A communication management method, wherein a computer executes:

• acquiring quantities of traffic of communications performed by one or more communication units operating in each of a plurality of computers constituting a cluster;
• predicting future quantities of traffic of the communications;
• calculating, for each of the computers, a total of the future quantities of traffic of the communication units operating in the computer and identifying a first computer for which the total exceeds a threshold;
• controlling, for a communication unit operating in the first computer, move to a second computer;
• predicting future quantities of traffic for the computers;
• selecting, among the communication units operating in the first computer, such a communication unit that the future quantity of traffic of the first computer is the closest to an average of the future quantities of traffic of the computers if the communication unit is moved from the first computer, as a target to be moved to the second computer;
• and
• selecting such a computer that the future quantity of traffic of the computer is the closest to an average of the future quantities of traffic of the computers if the communication unit targeted for the move moves to the computer, as the second computer.

A non-transitory computer readable medium storing a communication management program for enabling a computer to execute:

• acquiring quantities of traffic of communications performed by one or more communication units operating in each of a plurality of computers constituting a cluster;
• predicting future quantities of traffic of the communications;
• calculating, for each of the computers, a total of the future quantities of traffic of the communication units operating in the computer and identifying a first computer for which the total exceeds a threshold;
• controlling, for a communication unit operating in the first computer, move to a second computers;
• predicting future quantities of traffic for the computers;
• selecting, among the communication units operating in the first computer, such a communication unit that the future quantity of traffic of the first computer is the closest to an average of the future quantities of traffic of the computers if the communication unit is moved from the first computer, as a target to be moved to the second computer;
• and
• selecting such a computer that the future quantity of traffic of the computer is the closest to an average of the future quantities of traffic of the computers if the communication unit targeted for the move moves to the computer, as the second computer.
