The invention relates to a protocol data analysis, device and system. The method includes the steps: receiving protocol data to be matched, and pressing a terminal symbol of a protocol into a symbol stack; acquiring a current stack top state of a state stack and a current stack top symbol of a symbol stack; inputting the current stack top symbol into a lexical analyzer corresponding to the current stack top state; receiving a return result of the lexical analyzer; determining generation of a protocol event or a shift-in event according to the current stack top state and a terminal symbol with a predicate when the result is the terminal symbol with the predicate; pressing next state determined according to the current stack top state and the terminal symbol with the predicate in the state stack, and pressing the terminal symbol with the predicate into the symbol stack when the shift-in event is generated. By the aid of the technical field, number of pattern strings in the lexical analyzer can be decreased, lex
