Abstract: Provided is a communication control method of controlling communication between a first electrical switch and a second electrical switch each connected via an optical network and via an electrical network and each responsible for one or more devices to enable a data transfer with high reliability and low latency. The communication control method includes processes of (A) determining the presence or absence of blocking in relation to a first setup request of an optical circuit from the first electrical switch to the second electrical switch and (B) performing, if the blocking is present, at least one process of a first process of transmitting, from the first electrical switch, a second setup request of the optical circuit from the first electrical switch to the second electrical switch and a second process of transmitting a packet or a packet flow related to the first setup request from the first electrical switch via the electrical network.
