<p>A disclosed method executed by a first physical computer includes: measuring a transmission rate of data to be transmitted to a second physical computer, for a group to which virtual machines executed on the first physical computer belong; transmitting a request packet including the measured transmission rate to the second physical computer; receiving, from the second physical computer, a response packet including a ratio for the group and first data used in determining whether congestion has occurred; and upon determining based on the first data, that the congestion has occurred, lowering an output rate of data that the virtual machines belonging to the group output to the second physical server so as to be equal to or greater than a lower limit value determined by a product of the ratio for the group and a transmission rate that is preset for the group.</p> |
