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.

Network for an aircraft or spacecraft, and an aircraft or spacecraft including such network

A network for an aircraft including a master device and slave devices connected in daisy-chain arrangement series. Each slave device has a unique identifier. The master transmits polling data packets along the slave devices, each including only one identifier. Polling data packets are transmitted in successive sequences, each including for each slave device only one polling data packet and including the polling data packets in a predetermined order. Each slave device includes a first data interface for connection in an upstream direction, a second data interface for connection in the downstream direction, and a processing unit to compare for each received polling data packet the identifier thereof with the identifier of the respective slave device, and output a response data packet to the master device if the two identifiers match, and forward the polling data packet to the second interface at least if the two identifiers do not match.
