1. A communication system comprising:
a plurality of computing machines connected to an optical network,
wherein the optical network comprises a main signal communication path that is a lower layer of a communication scheme and a control communication path for transferring a control signal, and
wherein each computing machine comprises
a control unit that sets a remote direct memory access (RDMA) communication path, wherein to set the RDMA communication path, the control unit secures a memory area for RDMA communication,
a communication unit that transmits a setting request including setting information of the RDMA communication path set by the control unit and setting information for setting the main signal communication path to a computing machine of an access destination via the control communication path, and
a main signal transmitting/receiving unit that establishes the main signal communication path based on the setting information of the main signal communication path,
wherein communication unit further establishes the RDMA communication path on the established main signal communication path, wherein the RDMA communication path is an upper layer of the communication scheme.
