Problems solved by technology

The application layer protocol is a customized protocol, the communication content between different transceivers is quite different, the syntax and semantics of different application layer protocols are completely different, it is difficult to use a unified parser to analyze it, so there is a lack of universal The method of application layer protocol analysis

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0026] see figure 1 , the embodiment of the present invention includes:

[0027] A general network protocol analysis method mainly includes the following steps:

[0028] 1. The user first establishes the application layer network protocol model of the system based on the network protocol meta-model based on the application layer protocol of the actual system, and defines the parameters of each message model;

[0029] 2. After the entry is complete, click Save to store the entered model in the memory and file in the form of a multi-level tree structure;

[0030] 3. Input a certain network message to this method;

[0031] 4. After the method obt...

Abstract

The invention discloses a universal network protocol analysis method. The method aims at the specifications and characteristics of application layer protocols under different digital network channels, and the method comprises the following steps: 1) defining a semantic meta model for describing the application layer protocols; 2) defining modeling standards and specifications of a network application protocol; 3) describing a digital network application layer protocol model of a combat system based on a "tree" structure; and 4) designing an automatic protocol analysis method based on the semantic meta model. Verification shows that the method disclosed by the invention can satisfy the mainstream application layer protocols, and can provide guidance for the development of universal joint debugging apparatuses, test devices and simulators by means of protocol analysis requirements.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a general network protocol analysis method. Background technique [0002] A network protocol is a collection of rules, standards, or conventions established for data exchange in a computer network, and is a term used to describe the rules for exchanging information between processes. In a computer network, two entities that communicate with each other are located in different geographical locations, and the two processes on them communicate with each other. They need to coordinate their actions and achieve synchronization by exchanging information, and the exchange of information must be agreed in advance. process is carried out. A network protocol usually includes two parts. One is a standard protocol, which is usually defined by an organization or institution in the industry and is a specification that all communications must follow, such as: TCP / IP protocol, IPX / SPX proto...
