<p>There is provided a fibre channel fabric for interchanging frame by dividing a connectionless, variable length frame into fixed length cells wit houtcarrying out calling setup and/or releasing command between termination nodes, to thereby interchange cells, and further by reconstructing the thus interch anged cells into an original frame, the fibre channel fabric including (a) a fibre channel interface controller for communicating with a termination node or another fi bre channel fabric to control a fibre channel in protocol, (b) an input data buf fer for temporarily storing a frame received the termination node or the another fib re channel fabric, (c) a cell producer for dividing the frame received into fix ed length cells, (d) a cell switch for interchanging data at the unit of a fixed lengt h cell, (e) a frame constructor for reconstructing an original frame of the fixed length c ellstransmitted from the cell switch, (f) an output data buffer for temporarily storing a frame transmitted from the frame constructor, and (g) a congestion control ler for monitoring a load of the cell switch to thereby avoid congestion. The above- mentioned fibre channel fabric can be readily constructed as a hardware for enhancing interchangability, and provides a congestion controller having a simpler structure.</p> |
