Problems solved by technology

Wireshark is a widely used data packet analysis tool. In order to analyze custom communication protocols in Wireshark, it is often necessary to write corresponding LUA scripts. However, this requires a certain programming foundation. For non-programmers or those who are not familiar with Lua scripts There is a relatively high threshold for personnel, and for complex protocols, writing and debugging scripts is also very time-consuming

Embodiment Construction

[0051] The present invention will be further described below in conjunction with accompanying drawing.

[0052] In the field of network communication, the definition of data protocol generally follows the format definition of TLV, as shown in Table 1 below:

[0053] type Length value

[0054] Table 1

[0055] "T" stands for type (type), "L" stands for length (length), and "V" stands for data (value). This is the most common and basic data packet format definition, and all the following introductions will use this basic communication data definition as an example.

[0056] Predefined XML protocol engine:

[0057] XML tag design:

[0058] xs:element, used to represent the element in the data message means to represent the element in the data message.

[0059] xs:complexType, used to define multiple xs:element, custom complex types.

[0060] xs:simpleType, can be used to define enumerated types, custom simple types.

[0061] xs:sequence, which means that th...

Abstract

The invention discloses an XML (Extensive Markup Language)-based protocol analysis method for Wireshark, which comprises the following steps of describing the content of a data message protocol by using an XML tree structure according to the requirements of the data message protocol described in an ICD (Integrated Circuit Device) to form an XML document; enabling the XML protocol engine to automatically analyze the XML document, generate a corresponding protocol analysis tree and store the protocol analysis tree in a memory; and when the Wireshark processes the data message, automatically calling the protocol analysis tree in the memory to generate a corresponding analysis result. The Wireshark protocol analysis can be rapidly and conveniently realized.

Description

technical field [0001] The invention relates to a protocol analysis method for Wireshark based on XML. Background technique [0002] In the current software system, network-based communication is very common, and problems caused by communication errors are endless. Therefore, for developers and operators, protocol analysis tools in the communication process are very important. Wireshark is a widely used data packet analysis tool. In order to analyze custom communication protocols in Wireshark, it is often necessary to write corresponding LUA scripts. However, this requires a certain programming foundation. For non-programmers or those who are not familiar with Lua scripts There is a relatively high threshold for personnel, and for complex protocols, writing and debugging scripts is also very time-consuming. In actual work, test engineers and field engineers often need to view data packets between subsystems. How to implement Wireshark protocol analysis more conveniently an...
