Network control method, path control apparatus, network control system and path control program

A non-transitory computer-readable medium storing instructions executable by at least one processor to control a telecommunication network according to a method, the method comprising:

• calculating a total electric energy available for use by each communication apparatus of one or more communication apparatuses in a period, wherein the one or more communication apparatuses each comprises a network node in the telecommunication network;
• calculating electric energy available for use by each communication apparatus of the one or more communication apparatuses in a specified time zone based on the calculated total electric energy and on a distribution function that defines an amount of electric energy of the total electric energy available for use in one or more time zones in the period;
• determining, for each of the one or more communication apparatuses located on a communication path, based on a request to accommodate traffic in the specified time zone whether an expected power consumption to accommodate the traffic in the specified time zone exceeds the electric energy available for use in the specified time zone;
• and
• searching for communication paths through a subset of the one or more communication apparatuses;
• determining whether an expected power consumption of each apparatus in the subset to accommodate the traffic exceeds the calculated total electric energy;
• based on a determination that the expected power consumption for each apparatus in the subset to accommodate the traffic exceeds the calculated total electric energy, calculating an empty communication band for which an expected power consumption increase of a link along a path is less than expected power consumption increases for other links;
• and
• dividing a communication band of the paths based on the calculated empty band.

A telecommunication network control apparatus for controlling one or more communication apparatus, each comprising a network node in a telecommunication network, the apparatus comprising:

• at least one memory device storing computer-executable instructions;
• and
• a path control processor configured to execute the stored instructions to:
• calculate a total electric energy available for use by each communication apparatus of the one or more communication apparatuses in a period;
• calculate electric energy available for use by each communication apparatus of the one or more communication apparatuses in a specified time zone based on the calculated total electric energy available and on a distribution function that defines an amount of electric energy of the total electric energy available for use in one or more time zones in the period;
• determine, for each of the one or more communication apparatuses located on a communication path, based on a request to accommodate traffic in the specified time zone, whether an expected power consumption to accommodate the traffic in the specified time zone exceeds the electric energy available for use in the specified time zone;
• and
• search for communication paths through a subset of the one or more communication apparatuses;
• determine whether an expected power consumption of each apparatus in the subset to accommodate the traffic exceeds the calculated total electric energy;
• based on a determination that the expected power consumption for each apparatus in the subset to accommodate the traffic exceeds the calculated total electric energy, calculate an empty communication band for which an expected power consumption increase of a link along a path is less than expected power consumption increases for other links;
• and
• divide a communication band of the paths based on the calculated empty band.
