ABSTRACT:
A networking apparatus has its switching unit set a path for a data transfer from a processing apparatus on the data origination side to a processing apparatus on the data termination side. In case of a stop in the processing apparatus on the data origination side during the data transfer, the networking apparatus has its offline status detecting unit detect the stop by the presence or absence of an online status indication signal from the processing apparatus on the data origination side and generate an offline status indication signal. The networking apparatus has its controlling unit receive the offline status indication signal, and generate a simulated end-of-data signal, indicating a consummation of a data transfer, for transmission to a switching unit. The networking apparatus has its switching unit detect an end of data by receiving the simulated end-of-data signal, and cancel the path for the data transfer from the processing apparatus on the data origination side to the processing apparatus on the data termination side.
