Control device, storage medium, and optical communication system

A control device configured to instruct to switch a connection mode of an ONU in an optical communication system that includes a combination of PtP connection through which PtP communication is performed between the ONU and an optical terminal device of a communication partner and PtMP connection through which PtMP communication is performed with a plurality of the ONUs accommodated in an OSU,

• wherein the optical communication system includes an optical wavelength multiplexing/demultiplexing device between a core network and an ODN including the ONU,
• a predetermined number of first ports among a plurality of demultiplexing-side ports of the optical wavelength multiplexing/demultiplexing device are connected to the core network,
• a remaining second port among the plurality of demultiplexing-side ports is connected to a subscriber-side port of the OSU connected to the core network, and
• the control device instructs the optical terminal device in the optical communication system to switch a connection mode and a wavelength to be used by the ONU in response to change in use situation of a communication service.

A non-transitory computer readable storage medium having a control program recorded thereon, the control program being a control program of a control device configured to instruct to switch a connection mode of an ONU in an optical communication system including a combination of PtP connection through which PtP communication is performed between the ONU and an optical terminal device of a communication partner and PtMP connection through which PtMP communication is performed with a plurality of the ONUs accommodated in a OSU,

• wherein the optical communication system includes an optical wavelength multiplexing/demultiplexing device between a core network and an ODN including the ONU,
• a predetermined number of first ports among a plurality of demultiplexing-side ports of the optical wavelength multiplexing/demultiplexing device are connected to the core network,
• a remaining second port among the plurality of demultiplexing-side ports is connected to a subscriber-side port of the OSU connected to the core network, and
• the control program causes a computer to function as a switching instruction section configured to instruct the optical terminal device in the optical communication system to switch a connection mode and a wavelength to be used by the ONU in response to change in communication traffic of a communication service.
