Claim:
1. A method of communication through an optical communication network, executed by processor included in a communication apparatus that performs transmission by selecting a transmission mode, the method comprising: measuring an amount of data traffic of the optical communication network for each unit time when transmitting data; determining whether the measured amount of traffic data is equal to or more than a threshold value; transmitting the data using first optical signals having different levels in light intensity that indicate different numerical values when it is determined that the measured amount of traffic data is equal to or more than the threshold value; and transmitting the data using second optical signals having different levels in light intensity that indicate different numerical values, a number of types of the first optical signals being fewer than a number of types of the second optical signals, when it is determined that the measured amount of traffic data is not equal to or more than the threshold value.
