Latest Patents

Among his latest patents, Cathey has developed a programmable packet processor with flow resolution logic. This innovative packet switching controller features a packet buffer, a pattern match module, a programmable packet classification engine, and an application engine. The packet classification engine employs decision tree-based classification logic to effectively classify packets. Additionally, the application engine consists of several programmable sub-engines arranged in a pipelined architecture, including a source lookup engine, a destination lookup engine, and a disposition engine. These components work together to make disposition decisions for inbound packets within a processing pipeline.

Another significant patent by Cathey is also a programmable packet processor with flow resolution logic. This version includes a packet buffer that stores inbound packets and features a header data extractor. The header data extractor is responsible for extracting header data from the inbound packets and storing it in a header data cache. It also generates a header data cache index, which is provided to the packet classification engine for retrieving the extracted header data. The application engine in this patent similarly comprises programmable sub-engines that are organized in a pipelined architecture, enhancing the efficiency of packet processing.
