Realizing method and its device for communication protocol described by abstract grammar rule

Abstract

The present invention discloses abstract syntax rule descriptive communication protocol implementation method and device, to realize abstract syntax rule descriptive communication protocol and high efficiency to realize protocol coding decoding; furthermore also supporting user configuring data structure, supporting protocol specification adjusting, supporting error detection and process, and supporting user configuring operation processing. The present invention generates relevant specially realizing code and data structure to each kind communication protocol abstract syntax rule description, capable of directly compiling or explaining operation in communication entity; according to depth-first principle traversing syntax tree, parallel processing user configuring information, to generate node logical relationship fit data structure and realizing code; in advance establishing elementary data type process code library, directly taking for generating simple joint realizing code.

Description

technical field [0001] The invention relates to the realization technology of the communication protocol, in particular to the realization method and device of the communication protocol described by the abstract syntax rules. Background technique [0002] In a communication system, communication between different entities must be carried out according to a certain communication protocol. The interaction of messages of different communication devices is also carried out in accordance with the message format stipulated in the protocol. The realization of the communication protocol is the key step of the communication system. Each interface in the communication system has a dedicated communication protocol, including its message encoding method. At the same time, considering the transmission efficiency and other issues, most interface messages define their own encoding method. The sender encodes the message into a code stream according to the pre-agreed encoding rule, and th...

Problems solved by technology

[0023] In practical applications, the above solutions have the following problems: the general processing method adopted by the existing technical solutions seriously affects the encoding and decoding efficiency in the actual communication process; it does not support user-customized data structures, which affects the user's development efficiency and leads to a decrease in encoding and decoding performance ;Unable to flexibly adjust protocol specifications to meet actual needs; Unable to complete the detection and processing of codec errors; Unable to implement user-customized additional operation processing

[0024] The main reason for this situation is that the existing technical solutions use a general main program to query the data structure and call the function library to complete the encoding and decoding, which adds a query and calling step that consumes processing resources to the encoding and decoding process, which seriously affects Improved codec efficiency;

[0025] The existing technical solutions use fixed converters to generate data structures, which cannot establish data structures according to user-customized requirements, do not support user-customized data structures, and cannot flexibly adjust protocol specifications such as data scale, and the mismatch between user needs and data structures will Cause assignment errors, which in turn affect the efficiency of encoding and decoding;

[0026] The existing technical solutions use a fixed general-purpose main program for encoding and decoding, and it is impossible to add additional codes to complete user-customized operation processing, or to perform error detection and processing, etc.
