Method and device for ANBF string pattern matching and parsing

摘要

A method and an apparatus for string pattern matching and parsing based on ABNF syntax. The method includes: defining an instruction set suitable for describing a string pattern rule; designing a compiler capable of translating the protocol rule described in ABNF syntax into a protocol rule described with the instruction set and an object code; designing a hardware parser according to the characteristics of the instruction set, the parser comprising a module implemented by a special hardware for supporting the corresponding instruction, thereby realizing string pattern matching and parsing.
