Abstract
A communication network on board a vehicle is a deterministic switched Ethernet network using virtual links, including a set of subscriber devices and a set of switches in which communications are performed redundantly. To manage redundancy, each data frame transmitted on a virtual link includes a frame number in a numbering field of the frame. The transmitter and/or receiver subscriber devices on the virtual link take into account a length of the numbering field equal to a first predetermined length when the BAG value associated with the virtual link is greater than or equal to a predetermined BAG value, otherwise equal to a second predetermined length greater than the first length.
