Embodiment Construction

[0024] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Operating environment of the present invention is the target machine that VxWorks operating system is installed, and the network protocol stack diagram of VxWorks operating system is as figure 1 . Network cards of different brands (such as Intel, Broadcom) use different network card hardware drivers, and they will all go through the same Mux layer; different applications, using different transport layers (such as TCP, UDP), will also go through the same Mux layer . At the same time, in the network protocol stack of the VxWorks operating system, the Mux layer is on the dividing line related to the application software and the network card hardware. The network packets successfully received by the hardware will p...

Abstract

The invention discloses an Ethernet packet capturing method for a VxWorks operating system, and the method comprises the steps: storing an original function of a Mux layer, and constructing a packet capturing processing function mounting point; installing a message information storage function, and starting a packet capture function; capturing the message passing through the Mux layer, and writingthe message into persistent storage; and downloading the message information and reading in a visual form. According to the invention, the functions of capturing and storing the Ethernet network message information of the VxWorks operating system are realized. The receiving and sending time and network message information of all received and sent messages of the Ethernet in a period of time of atarget machine operating system can be stored in the persistent storage of the target machine, and then the network message of the target machine is acquired and read through a method downloaded by anupper computer. Debugging means under the VxWorks operating system can be enriched, and the development efficiency of application software based on the Ethernet is improved.

Description

technical field [0001] The invention belongs to the technical field of embedded software development, and relates to an Ethernet packet capture method for a VxWorks operating system. Background technique [0002] At present, Ethernet communication is an important high-speed communication method in embedded systems. Ethernet packet capture is a common technology in the development of Ethernet communication. It refers to the technology to capture all the Ethernet message information received by the hardware network card and display it in a human-readable form. Common general-purpose operating systems Windows and Linux have Ethernet packet capture software such as WireShark, Fiddler, etc., to assist the development of application software based on Ethernet communication. [0003] The VxWorks operating system commonly used in embedded development does not have the application software function of Ethernet packet capture, which makes it difficult to develop Ethernet-based applic...
