Abstract: In systems with high reliability requirements for network communication, dual redundancy backup for network cards is necessary. When the active network card or line fails, it can automatically switch to the backup network card. This article details the implementation of a dual network card redundancy backup technology in the real-time operating system VxWorks. Keywords: … Read more
