Abstract
A computer-based method and system for performing header filtering of data is presented The method comprises compressing the header of a data packet to obtain a header signature and determining if the header signature matches a known header signature. If the header signature is determined to have a match, then the header signature is identified as a known header signature. A header signature may be generated using a multidimensional data compression algorithm. A compression algorithm comprises obtaining the data bits contained in each field of a typical header. Then, a header-field group that corresponds uniquely to each field is determined. Each field is replaced with the header-field group of the corresponding data bits of the field and concatenated to create a header signature.
