Communication device, communication control method, and non-transitory computer-readable medium

A communication control method comprising:

• acquiring a plurality of measurement values related to communication quality information in an optical communication network;
• calculating an average value of measurement values for each first time section based on the plurality of measurement values, determining a variance of the measurement values for each first time section, and determining a reference quality value based on the average value and the variance, the reference quality value being an index value indicating communication quality in the optical communication network,
• determining whether the communication quality satisfies a required quality value based on the reference quality value;
• and
• changing a communication setting in the optical communication network so that the communication quality satisfies the required quality value.

A non-transitory computer-readable medium storing a program for causing a communication device to execute a communication control method, the communication control method comprising:

• acquiring a plurality of measurement values related to communication quality information in an optical communication network;
• calculating an average value of measurement values for each first time section based on the plurality of measurement values, determining a variance of the measurement values for each first time section, and determining a reference quality value based on the average value and the variance, the reference quality value being an index value indicating communication quality in the optical communication network;
• and
• determining whether the communication quality satisfies a required quality value based on the reference quality value,
• hanging a communication setting in the optical communication network so that the communication quality satisfies the required quality value.
