METHOD AND DEVICE FOR DATA MAPPING, AND METHOD AND DEVICE FOR DATA DEMAPPING

摘要

The present invention discloses a method and device for data mapping. The method includes: encoding Fiber Channel (FC) data into valid data packets, and outputting the encoded valid data packets, wherein the 0th bit of the 0th byte of each valid data packet is 1; receiving and buffering the valid data packets, and outputting the buffered valid data packets as Optical channel Payload Unit-k (OPUk) data when the number of all the buffered valid data packets is not less than a predetermined threshold. The present invention also discloses a method and device for data demapping. Application of the present invention can avoid a Generic Framing Procedure (GFP) encapsulation process, thereby reducing complexity of the implementation of an FC system.
