ABSTRACT:
A network device for processing data on a data network including a plurality of ports, configured to receive data packets and to send out processed data packets, a modification engine configured to parse, evaluate and modify the data packets to produce the processed data packets and a series of search engine pipeline stages configured to perform lookup searches through a plurality of search engines. The series of search engine pipeline stages perform search requests in sequential processing steps and any stage of the series of search engine pipeline stages may submit a particular search request to the plurality of search engines and receive search results particular to a particular data packet at a respective processing step.
