Title: Joseph Dempsey: Innovator in Packet Classification Technology
Introduction
Joseph Dempsey is a notable inventor based in Austin, TX (US). He has made significant contributions to the field of network processing, particularly in the area of packet classification. His innovative approach has led to the development of a unique system that enhances the efficiency of network data handling.
Latest Patents
Joseph Dempsey holds a patent for a "System and method for dynamically constructing packet classification rules." This invention involves a system and method that classifies packets using a programmably fixed network processor program and dynamically updated data structures. The network processor program selects predetermined packet field values of the packets transmitted across the network and classifies the packets by matching one or more packet field values with a data structure. New packet classifications are dynamically created by updating the data structure to associate one or more predetermined packet field values with the new packet classification. For instance, a parse tree program extracts packet header information and matches it to the data structure. A pattern tree data structure provides longest prefix matches, while an ordered tree data structure allows for combination matches, enabling the classification of arbitrary Boolean combinations of extracted header fields.
