METHOD AND APPARATUS FOR INSPECTION OF COMPRESSED DATA PACKAGES

Michael Stübert Berger (Inventor), Brian Bach Mortensen (Inventor)

Research output: Patent

Abstract

A method for inspection of compressed data packages, which are transported over a data network, is provided. The data packages comprise a data package header containing control data for securing the correct delivery and interpretation of the package and a payload part containing data to be transferred over the data network. The method comprises the steps of: a) extracting payload data from the payload part of the package, b) appending the extracted payload data to a stream of data, c) probing the data package header so as to determine the compression scheme that is applied to the payload data, d) applying the determined compression scheme to at least one search pattern, which has previously been stored in a search key register, and e) comparing the compressed search pattern to the stream of data. The method can be carried out by dedicated hardware.
