Abstract

The present invention relates to a network for an aircraft (1), comprising a data line (3), and at least two network access devices (4), comprising a first interface (9) and at least one second interface (10) and being connected to the data line (3) via the first interface (9). Identifiers are assigned to the second interfaces (10) in pairs. The network access devices (4) are adapted to receive and/or transmit data via the first interface (9) in first data frames (5) having a fixed format and comprising a first portion (17) and second portions (18) following the first portion (17), the first and second portions (17, 18) having predefined lengths and locations within the first data frame (5). The network access devices (4) are to transmit in the first data frames (5) a sequence of second data frames (12) and, for each second interface (10), a sequence of third data frames (13a, 13b) received on the second interfaces (10), wherein the network access device (4) includes a first processing unit (7) adapted to insert the second data frames (12) in the first portion (17) of the first data frames (5), split each third data frame (13a, 13b) into a plurality of fragment frames (20a, 20b), including a part (19a, 19b) of the respective third data frame (13a, 13b) and reassembly information allowing regeneration of the third data frame (13a, 13b) from the fragment frames (20a, 20b), and insert the fragment frames (20a, 20b) into the second portions (18). The network access devices (4) are also adapted to process received first data frames (5) by extracting the second data frame (12) and the fragment frames (20a, 20b), to regenerate the corresponding third data frames (13a, 13b), and to output the regenerated third data frames (13a, 13b) on corresponding second interface (10).
