Abstract

A network for an aircraft including a data line and network access devices, a first interface and at least one second interface and connected to the data line via the first interface. Identifiers are assigned to the second interfaces in pairs. The access devices receive and/or transmit data in first data frames having a fixed format and first portion and second portions. The network access devices transmit second data frames and, for each second interface, a sequence of third data frames received on the second interfaces, the network access device including a first processing unit to insert the second data frames in the first portion of the first data frames, split each third data frame into fragment frames, including a part of the respective third data frame and reassembly information allowing regeneration of the third data frame from the fragment frames, and insert the fragment frames into the second portions.
