1. A communication control apparatus configured to relay communication between a plurality of satellites and other equipment, the communication control apparatus comprising:
a plurality of optical communication units that are capable of performing optical communication in parallel with the plurality of satellites;
an equipment communication unit configured to communicate with the other equipment; and
a processor that is configured to:
set a first data rate that is a sum of data communication rates per unit time between the plurality of satellites and the plurality of optical communication units, and to set a second data rate that is a limit value of a data communication rate per unit time between the communication control apparatus and the other equipment;
control the plurality of optical communication units and the equipment communication unit such that data received by the plurality of optical communication units from the plurality of satellites at the first data rate is relay transferred in parallel to the other equipment at not greater than the second data rate;
set a maximum number Nop of the optical communication units able to perform optical communication in parallel with the plurality of satellites,
wherein the maximum number Nop being a greatest integer that does not exceed a quotient obtained by dividing a limit value RG of the second data rate by a limit value RU of a data rate between one of the satellites and one of the optical communication units,
the limit value RG being not less than the limit value RU; and
control the optical communication units such that Nop of the optical communication units are employed at a maximum to perform optical communication in parallel with the plurality of satellites.
