Abstract:
1. A method for operating a transport interface for at least one local Fibre Channel port, said transport interface providing a mechanism to adapt Fibre Channel frames for transport over a SONET/SDH network, said method comprising: receiving a plurality of Fibre Channel frames from said at least one local Fibre Channel port at a data rate greater than a data rate of said SONET/SDH network, for transmission to at least one remote Fibre Channel port; and encapsulating said plurality of said Fibre Channel frames directly into a frame-mode Generic Framing Protocol (GFP) frame for transport over said SONET/SDH network from said at least one local Fibre Channel port to said at least one remote Fibre Channel port, further comprising inserting a payload header into said frame-mode GFP frame, said payload header having a User Payload Identifier (UPI) including a bit pattern selected from the range, “1111 0000” through “1111 1110”, for eight bits UPI[7:0], said selected bit pattern indicative of Fibre Channel data with a Distributed Delimiter in a payload information field of said frame-mode GFP frame.
