ABSTRACT:
Proxy FC ports in an FC network are connected between first and second FC (Fibre Channel) devices having reception buffers and first and second FC transfer apparatuses connected to each other through a WAN (Wide Area Network). The proxy FC ports transfer signals to be exchanged between the first and second FC devices. The proxy FC ports include Frame FIFOs and transmission control sections. The Frame FIFOs have larger capacities than the reception buffers. The transmission control section performs flow control on the first and second FC devices on the basis of the remaining capacities of the Frame FIFOs. An FC network system and FC transfer method are also dislosed.
