Abstract: A computer-implemented method for compressing a first stream of data, the first stream of data comprising a plurality of input words. The computer-implemented method includes receiving the plurality input words, and adaptively compressing the plurality of input words into a plurality of compression codes. The computer-implemented method further includes outputting the plurality of compression codes upon encountering an end-of-file signal in the first stream of data, wherein the plurality of compression codes are fewer in number than the number of unique bit patterns requiring unique compression codes under LZW (Lempel Ziv & Welch) compression.

Abstract: Adaptive compression and decompression techniques are described. In at least some embodiments, compression techniques include adaptively compressing a plurality of input words into a plurality of compression codes and outputting the compression codes upon encountering an end-of-file signal. In at least some embodiments, the compression codes are fewer in number than the number of unique bit patterns requiring unique compression codes under LZW (Lempel Ziv & Welch) compression. In at least some other embodiments, decompression techniques include adaptively decompressing a plurality of compressed code words into a plurality of decompressed words and outputting the decompressed words upon encountering an end-of-file signal.

Abstract: A data optimization engine disposed inline with a first communication channel and a second communication channel. The data optimization engine comprises a transmit interface circuit configured to receive a first data stream from the first communication channel and to obtain a first data file from the first data stream. The data optimization engine further includes an optimization processor coupled to the transmit interface circuit for receiving a second data file from the transmit interface circuit.

The optimization processor performs one of a compression and an encryption on the second data file, thereby obtaining all optimized data file. In one embodiment, the first data file is a Fiber Channel data frame.
