Abstract

A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a structured application layer message and identifies, in message classification requirements at the network device, a reference to a classification portion of the structured application layer message and an operation portion of the structured application layer message. The system extracts, based on one or more expressions, a portion of the message for classifying the structured application layer message and classifies the message using the extracted portion and according to the message classification requirements. At least in part by accessing information indicated by one or more location identifiers, at least one operation is performed on the classified structured application layer message.
