Abstract

Embodiments of the apparatus for handling large protocol layers relate to an implementation that optimizes a field selection circuit. This implementation provides software like flexibility to a hardware parser engine in parsing packets. The implementation limits a size of each layer and splits any layer that exceeds that size into smaller layers. The parser engine extracts data from the split layers just as it would from a non-split layer and, then, concatenates the extracted data in a final result.
