Abstract: A multi-protocol, multi-stage, real-time frame classifier is disclosed. A preliminary multi-protocol frame composition analyzer is provided for performing preliminary multi-protocol frame classification for incoming frames. A parsing instruction generator is provided for processing at least the incoming frame and the preliminary multi-protocol frame classification to provide parsing instructions. A multi-stage parsing engine provides multi-stage parsing of the incoming frame according to the parsing instructions to generate search results presenting information about the incoming frame. An advanced level of data extraction is provided across various frame protocols without imposing a performance penalty. Longest prefix match searches and/or direct lookup searches are supported. Moreover, conditional extractions, instruction branching, multi-stage processing are all performed in real time.

Abstract: A system and method for facilitating packet transformation of multi-protocol, multi-flow, streaming data. Packet portions subject to change are temporarily stored, and acted upon through processing of protocol-dependent instructions, resulting in a protocol-dependent modification of the temporarily stored packet information. Validity tags are associated with different segments of the temporarily-stored packet, where the state of each tag determines whether its corresponding packet segment will form part of the resulting modified packet. Only those packet segments identified as being part of the resulting modified packet are reassembled prior to dispatch of the packet.

Abstract: An accelerated processing system includes one or more conventional processors, one or more coprocessors, and high speed data links between the processors, coprocessors and memory. In an embodiment, an application program is compiled and linked to a library of macros, the macros are invoked at run time by the application program, the application program marks data to be processed by the one or more coprocessors. A service and control coprocessor streams the marked data to the one or more coprocessors for processing. In an embodiment, a coprocessor is configured to analyze software code and data, to schedule processing of the software code and data in another coprocessor, and to manipulate the data based on the type of data that the other coprocessor is configured to process.
