Abstract
Systems and methods for compression of data to be transmitted are described. A data stream, such as a byte code sequence, is partitioned into one or more data chunks. The data chunks can be associated with an identifier, such as a signature that differentiates one data chunk from the other. Thus, different data chunks would be identifiable through different signatures. The data chunks associated with the signatures can be compared with a repository or a history buffer. The history buffer includes a collection of previously transmitted data chunks each associated with their respective signature.
