A Content Security-Oriented Packet Parsing Architecture(CSOPPA) was proposed to achieve high-speed network protocol parses flexibly. First, the content extraction-trie (CE-trie) was defined to describe the parsing relationship of the protocol flexibly, then a parallel pipeline was designed to meet the wire-speed parsing, and a node balanced mapping algorithm (NBMA) was proposed to achieve the balance of the number of nodes among different pipeline stages. Finally, the feasibility of CSOPPA was verified on NetFPGA-10G platform. The simulation results showed that CSOPPA achieves the balance between the performance and resource consumption.
