Latest Patents
Kusaba's latest patents include a "Station-side apparatus and frame transfer apparatus" and an "OLT and frame transfer control method." The first patent focuses on the registration of identifier information (LLID) of an ONU and transfer instruction information that indicates a transmission system as the output destination of a downstream frame. This information is organized in a table corresponding to the destination IDs of the ONUs or user apparatuses connected to them. Upon receiving a downstream frame from a host apparatus, a frame transfer processing unit acquires the LLID and transfer instruction information from the table.
The second patent involves a control frame processing unit that counts the number of control frames from a frame demultiplexing unit for each LLID assigned to the control frames. If the number of frames during a predetermined count period is equal to or smaller than a preset threshold, some or all of the control frames are written in a storage device as processing data. When the number of frames exceeds the threshold, writing data of the control frames with the LLID in the storage device is halted. This innovation ensures that software processing can be executed properly, even when the number of control frames from ONUs increases.
