Abstract
A communication apparatus capable of easily grasping a communication quality status includes: an acquisition unit configured to acquire measured values of a predetermined number or more measured for communication quality information in an optical communication path; an estimation unit configured to calculate an average value of the acquired measured values, generate a first cumulative distribution function of the communication quality information based on the acquired measured values, and estimate a second cumulative distribution function of the communication quality information based on measured values when the measured values more than a number of the acquired measured values are acquired based on the average value and the first cumulative distribution function; and a determination unit configured to determine a value of the communication quality information as a reference quality value, a cumulative probability in the second cumulative distribution function becoming a predetermined value at the value of the communication quality information.
