OPTICAL COMMUNICATION CONTROL DEVICE, OPTICAL COMMUNICATION CONTROL METHOD, AND OPTICAL COMMUNICATION CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/113167
Kind Code:
A1
Abstract:
This optical communication control device performs energy-efficient control of a communication system in which a first communication device and a second communication device art redundantly connected by a first path, which is connected to an ONU and an OLT, and a second path, and comprises: a monitoring unit which monitors the amount of traffic between the ONU and the OLT, and a command unit which, if the amount of traffic is less than a predetermined sleep threshold, performs processing for transmitting to the first communication device and the second communication device an allocation command for allocating traffic from the first path to the second path, processing for transmitting a link hold command to the OLT, and processing for transmitting a sleep command to the ONU.
