Abstract

The invention discloses a processing method of application layer protocol messages between a single-network-card VxWorks system and multiple hosts. An effect that received data cannot be lost is guaranteed according to task priority provided by the VxWorks system; data classification is carried out according to IP address difference, and the data are decomposed into multiple different sub-data blocks; and semaphore is used to ensure parallel processing of the data, and a data processing range is reduced. According to the method of the invention, data structures and processing logic are clear,corresponding communication objects and data of VxWorks task abnormalities can be conveniently and quickly distinguished and located, problem tracking and locating are facilitated, help is provided for problem solving, and thus product research and development progress is accelerated. The method achieves a better result 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...
