Abstract: An optical line terminal (OLT) (1) includes an interface (I/F) board (2) configured to communicate with an external apparatus, a graphics processing unit (GPU) (4) configured to perform a first process, and a central processing unit (CPU) (3) configured to control the I/F board (2) and the GPU (4). The CPU (3) includes a data processing execution unit configured to execute a second process, an external transfer control unit configured to perform a control process of transferring data received from the external apparatus from the I/F board (2) to the CPU (3) or the GPU (4) and a control process for transferring data to be transmitted to the external apparatus from the CPU (3) or the GPU (4) to the I/F board (2), a data processing control unit configured to perform control for executing the first process of the GPU (4) and the second process of the CPU (3) on the data received from the external apparatus or the data to be transmitted to the external apparatus; and a processing result copy unit configured to perform control for outputting a processing result of the first process to the CPU (3) and designating the processing result of the first process as a processing target of the second process and control for outputting a processing result of the second process to the GPU (4) and designating the processing result of the second process as a processing target of the first process.

Abstract: A service start method is a service start method executed by a communication system, and the service start method includes: a step of acquiring identification information or authentication information of a device, a customer, or a service; a step of making authentication of the device, the customer, or the service to succeed when the identification information or the authentication information has been acquired together with information that is associated with the customer or a customer's location in advance, or when the identification information or the authentication information has been acquired from a terminal or a line that is associated with the customer in advance; and a step of starting provision of the service for the device for which the authentication has succeeded.
