Abstract
An integrated circuit has a hardware decoder that parses a frame to identify a type of encapsulation. The integrated circuit also has a number of hardware parsers, each parser being coupled to the decoder by an enable line. During packet processing, one of the parsers is enabled by the decoder, based on the value which identifies the encapsulation type. The enabled parser retrieves one or more attributes from the frame, depending on the encapsulation. The integrated circuit also has a register, coupled to each parser, to hold the attributes. The integrated circuit also has a key generation hardware which creates a key, by concatenating from the attributes register, certain attributes that are pre-selected by a user for forming the key. The integrated circuit uses the key to look up in memory a set of user-specified actions that are then performed on data in the frame.
