Method for describing protocol by using XML and protocol resolving system built by same

Abstract

The invention discloses a method for describing a protocol by using an XML and a protocol resolving system built by the same, namely the method for describing the protocol by using the XML and a system which is built based on the method and is used for resolving an industrial Ethernet protocol. The method for describing the protocol by using the XML comprises two aspects, wherein one is the method for describing an Ethernet protocol format by using the XML and the other one is the method for describing a protocol suite relationship by using the XML. The system for resolving the industrial Ethernet protocol comprises two parts, namely a hardware system and a software system, wherein the hardware system comprises a network adapter and a host machine; and the software system comprises five units, namely a protocol load unit, a protocol library unit, a data capture unit, a protocol match unit and a data resolving unit. The method and the system can conveniently realize the modification and expansion of protocol contents, realize the screening, match and resolving of a multi-layer protocol, and have wide practical value and application prospect in the technical field of Ethernet.

Description

(1) Technical field: [0001] The present invention belongs to the technical field of industrial Ethernet, and specifically relates to a method for describing a protocol using an extensible markup language (eXtensible Markup Language, XML for short), and a method for analyzing industrial Ethernet protocols established based on this method. system. (2) Technical background [0002] Industrial Ethernet technology is a new product of the development of Ethernet. There is no targeted dedicated protocol analysis system, and only the existing general Ethernet protocol analysis system can be used. The functions implemented by these analysis systems are very rich, but they all use the program codes of their own specific formats to describe the protocol format and protocol cluster relationship. Such protocol description methods are generally not very open, which will cause the types and numbers of protocols supported by the analysis system to be relatively large. fixed. Some resoluti...

AI Technical Summary

Problems solved by technology

[0004] 1. Some protocol analysis systems do not support protocol modification and expansion;

[0005] 2. The protocol description method of the protocol analysis system is complex, the development of the protocol interface is difficult, the technical level of the developer is high, and the development cycle is long;

[0006] 3. The protocol description method of the protocol analysis system is complicated, and it is impossible to intuitively judge whether the protocol interface program is correct, so the modified or added protocol interface will make the system unreliable;

[0007] 4. Protocol description methods vary greatly between different protocol analysis systems, and it is basically impossible to implement universal protocol interfaces
