Abstract

The invention discloses a method for processing application layer protocol messages between a single network card VxWorks system and multiple hosts. According to the task priority provided by the VxWorks system, it is guaranteed that data reception will not be lost; data is classified according to different IP addresses, and the data is decomposed into multiple different sub-data blocks; use semaphores to ensure parallel processing of data, and reduce the scope of data processing; the data structure and processing logic of the method of the present invention are clear, and can conveniently and quickly distinguish and locate the corresponding communication objects and data of abnormal VxWorks tasks, which is convenient for problem tracking and positioning , to help solve problems, thus speeding up the progress of product development. This method has achieved good results in actual product development.

Description

technical field [0001] The invention relates to the technical field related to an embedded operating system, in particular to a method for processing application layer protocol messages between a VxWorks system with a single network card and multiple hosts. Background technique [0002] In the field of embedded technology, the VxWorks system is a real-time embedded operating system with good real-time performance and is widely used in the military industry. Tailorability is an important feature of embedded systems. The operating system generally runs on a specific hardware platform, and communicates with multiple hosts through the network to realize protocol message interaction between system devices, and finally completes behavior understanding between system devices. However, a hardware platform with multiple network cards is more expensive than a hardware platform with a single network card. Therefore, on the premise of meeting the requirements, it is a better and more e...
