Abstract

A data transmission architecture, in particular for use in on-board avionics is disclosed. The data transmission architecture includes at least one main data transmission network with integrated functional nodes for connecting a plurality of peripheral data transmission networks to the main network, in order to provide data transmission between the networks. The data transmission architecture also includes a direct connection of peripheral networks to one another so as to allow the transmission of data directly between the peripheral networks without passing through the main network. The main network includes a plurality of associated sub-networks.

Claims

1. A data transmission architecture for use in on-board avionics, comprising:

at least one main data transmission network with integrated functional nodes for connecting a plurality of peripheral data transmission networks to the main network, in order to provide data transmission between the networks; and

a direct connection of peripheral networks to one another so as to allow the transmission of data directly between the peripheral networks without passing through the main network,

wherein the main network includes a plurality of associated sub-networks.

2. The data transmission architecture according to claim 1, wherein the main network and/or the peripheral data transmission networks include redundant data transmission supports.

3. The data transmission architecture according to claim 1, wherein the main network and/or the peripheral data transmission networks include switches.

4. The data transmission architecture according claim 1, wherein the main network and/or the peripheral data transmission networks are looped networks.

5. The data transmission architecture according to claim 1, wherein the main network and/or the peripheral data transmission networks are star networks.

6. The data transmission architecture according to claim 1, wherein at least one peripheral data transmission network assumes the form of a looped network for the unconditional transmission of messages from node to node, independently of those messages.

7. The data transmission architecture according to claim 1, wherein at least one peripheral data transmission network assumes the form of a looped network for the conditional transmission of messages from node to node, dependent on those messages.

8. The data transmission architecture according to claim 1, wherein at least some of the data transmission networks are unidirectional.

9. The data transmission architecture according to claim 1, wherein at least some of the data transmission networks are bidirectional.

10. The data transmission architecture according to claim 1, wherein the functional connecting nodes comprise an extraction/injection/monitoring capability for frames of and in the networks.

11. The data transmission architecture according to claim 1, wherein at least some of the functional nodes are programmable.

12. The data transmission architecture according to claim 10, wherein at least some of the functional nodes are programmable and wherein the frame extraction/injection/monitoring capability of the programmable node uses a programming database stored in a corresponding storage capability.

13. The data transmission architecture according to claim 2, wherein the main network and the peripheral data transmission networks include data transmission supports that are completely or partially redundant associated by redundancy plane.
