1. An optical line terminal comprising:
one or more optical line termination circuits to each of which one or more optical network units of an optical communication system is connected, the one or more optical line termination circuits acquiring an allocation requested bandwidth from the one or more optical network units connected;
a slice management circuit to manage slice configuration information indicating which slice each of the optical network units connected to the optical line termination circuit is included in, and manage a limitation on allocation of bandwidth for the one or more optical network units as a parameter for allocating bandwidth; and
a bandwidth allocation circuit to determine, for each of the slice, an allocated bandwidth for each of the optical network units connected to the optical line termination circuit on the basis of the allocation requested bandwidth, the slice configuration information, and the parameter for allocating bandwidth.
