Abstract
An optical line terminal includes a communication unit configured to communicate with a plurality of optical network units, and a control unit configured to dynamically change at least one of a time width of a specific period and a cycle of the specific period, the specific period being a period in which an authentication request signal is received from the new optical network unit via the communication unit.
Claims7
An optical line terminal comprising:
- a communicator configured to communicate with a plurality of optical network units;
- and
- a controller configured to dynamically change at least one of a time width of a specific period and a cycle of the specific period, the specific period being a period in which an authentication request signal is received from a new optical network unit via the communicator,
- wherein the controller changes at least one of a time width of the specific period and a cycle of the specific period based on authentication statuses of the plurality of optical network units,
- wherein the controller changes the time width so that a probability of the optical network unit that is expected to be authenticated in one specific period becomes equal to or greater than a preset threshold with respect to an unauthenticated number that is the number of unauthenticated optical network units.

A registration method in which an optical line terminal registers a new optical network unit, the method comprising:
- dynamically changing at least one of a time width of a specific period for receiving an authentication request signal from the new optical network unit and a cycle of the specific period;
- and
- registering the optical network unit that has transmitted the received authentication request signal in a case where the authentication request signal is received from the new optical network unit within the specific period changed,
- changing at least one of a time width of the specific period and a cycle of the specific period based on authentication statuses of a plurality of optical network units,
- changing the time width so that a probability of the optical network unit that is expected to be authenticated in one specific period becomes equal to or greater than a preset threshold with respect to an unauthenticated number that is the number of unauthenticated optical network units.
