PARSER ENGINE PROGRAMMING TOOL FOR PROGRAMMABLE NETWORK DEVICES

摘要

A parser engine programming tool configured to receive an input file representing a directly connected cyclical graph or tree of decision points for parsing a range of incoming packet headers, automatically generate all possible paths within the graph and thereby the associated possible headers, and convert the determined paths/headers into a proper format for programming memory of a parser engine to parse the determined headers (represented by the paths).

主权项

1. A processing network comprising:
a processing circuit having a programmable parser including one or more parsing engines that parse data packets received by the processing circuit; and a parser compiler stored on a non-transitory computer-readable memory and communicatively coupled with each of the parsing engines, wherein the parser compiler is configured to generate values based on a parser configuration file that when programmed into a memory associated with each of the parsing engines enables the parsing engines to identify each of a set of different combinations of packet headers represented by the parser configuration file.
