Identification of data stored in memory

A non-transitory computer readable medium having embodied thereon a program, the program being executable by a processor for performing a method for generating a retrieval instruction based on matched data, the method comprising:

• receiving a first data packet;
• comparing a first packet byte within the first data packet to a first memory byte within a memory, the memory comprising a first persistent memory and a second faster memory, at least the second faster memory residing in a network memory appliance;
• determining a mismatch between the first packet byte and the first memory byte;
• jumping to a memory location containing a second memory byte that is non-consecutive with the first memory byte;
• jumping to a packet location containing a second packet byte that is non-consecutive with the first packet byte;
• comparing the second packet byte to the second memory byte;
• receiving a second data packet associated with the same Internet Protocol flow as the first data packet;
• comparing a packet byte of the second data packet to a packet byte of the memory;
• generating a retrieval instruction configured to transform one or more bytes in memory based at least in part on a result of the comparison between the second packet byte and the second memory byte;
• pre-scanning the data packet to generate a sample fingerprint;
• identifying stored fingerprints identical to the sample fingerprint;
• and
• copying the first memory byte from the first persistent memory to the second faster memory based on the identification of matches with the identified stored fingerprints.
