A Protocol Driving Communication Technology

Currently when computers communicate with peripherals which have various application-layer protocols, we have to write particular communication interfaces to talk with those peripherals. This always causes complexity and redundance. Although these application-layer protocols are different from each other, they do have one same structure. Such as some bytes represent the command type, some bytes represent the data type, still some bytes represent the data value. So what we can do is formalize these protocols according this characteristic. Just like what we do to all those computer languages!Lexical analysis is the first step in analyzing computer language. A particular lexical analyzer can analyze one type of computer language no matter how programmers write it. While a lexical analyzer generator can generate various lexical analyzers. In this paper an effective and efficient solution to the problem will be introduced according to the lexical analyzer generator theory.
