Abstract

A method for allocation of network resources in an operations network for a selected environment includes, among other things, a plurality of applications communicating over a network having a bandwidth capacity and a plurality of modes including at least a first mode and a second mode.

Claims

1. A method for allocation of network resources in a deterministic operations network comprising data transmitting and receiving devices, at least one computer processor, and a plurality of applications communicating data over the deterministic operations network in an aircraft, the deterministic operations network having a bandwidth capacity in at least a first mode or a second mode, the method comprising the steps of:

determining in the at least one computer processor a set of first preferred applications of the plurality of applications for communicating over the deterministic operations network in the first mode and a set of second preferred applications of the plurality of applications for communicating over the deterministic operations network in the second mode;

allocating in the at least one computer processor a first portion of the bandwidth capacity to the set of first preferred applications in the first mode and a second portion of the bandwidth capacity to the set of second preferred applications in the second mode;

selecting the first mode or the second mode for operation of the deterministic operations network; and

operating the deterministic operations network via the at least one computer processor according to the allocation wherein the first set of preferred applications uses the first portion of the bandwidth capacity when the deterministic operations network is operating in the first mode and the second set of preferred applications uses the second portion of the bandwidth capacity when deterministic operations network is operating in the second mode of operation.

2. The method of claim 1 wherein the first set of preferred applications has at least one application different than the second set of preferred applications.

3. The method of claim 1 wherein the first set of preferred applications is the same as the second set of preferred applications, but the allocations of the bandwidth capacity differ for at least one of the preferred applications in the first mode and the second mode.

4. The method of claim 1 wherein the first portion of the bandwidth capacity allocated to the set of first preferred applications in the first mode is different than the second portion of the bandwidth capacity allocated to the set of second preferred applications in the second mode.

5. The method of claim 1 and further comprising at least one additional mode that is different from the first mode and the second mode.

6. The method of claim 1 wherein the first portion of the bandwidth capacity allocated to the set of first preferred applications in the first mode and the second portion of the bandwidth capacity allocated to the set of second preferred applications in the second mode exceeds the bandwidth capacity of the deterministic operations network.

7. The method of claim 1 and further comprising providing at least one of a hardware interlock and a logical interlock to enforce operating the deterministic operations network according to the allocation.

8. The method of claim 1 wherein the first portion of the bandwidth capacity allocated to the set of first preferred applications in the first mode and the second portion of the bandwidth capacity allocated to the set of second preferred applications in the second mode is measured by a percentage of network link capacity utilized by a corresponding application on the deterministic operations network.

9. The method of claim 1 wherein the set of first preferred applications of the plurality of applications communicating over the deterministic operations network in the first mode comprises applications necessary to maintain safety-critical operations of the selected environment.

10. The method of claim 1 and further comprising maximizing network traffic for safety-critical operations when the deterministic operations network is operated in the first mode.

11. The method of claim 1 and further comprising maximizing network traffic for maintenance operations when the deterministic operations network is operated in the second mode.

12. The method of claim 1 further comprising transmitting at least one of maintenance data, flight data, engine condition monitoring data, recorder logs, and passenger manifest data when the deterministic operations network is operated in the second mode.

13. The method of claim 1 and further comprising manually switching between the first mode and the second mode when the operating conditions of the selected environment either change or are expected to change.

14. The method of claim 1 and further comprising automatically switching via the at least one computer processor between the first mode and the second mode based upon at least one preselected criterion.

15. The method of claim 1 wherein each of the plurality of applications comprises a computer-implemented process including at least one of an application, a service, a process, a batch, and an executable.

16. The method of claim 1 wherein the deterministic operations network comprises at least one of a LAN, a WAN, an Ethernet, a wired computer network, and a wireless network.

17. The method of claim 1 where the first set of preferred applications and the second set of preferred applications each includes a subset of safety critical applications necessary for basic operation of the selected environment.

18. The method of claim 1 and further comprising analyzing in the at least one computer processor the first and second sets of preferred applications to ensure that each set of preferred applications meets operational requirements specified for each mode of the selected environment.

19. The method of claim 1 wherein the first mode comprises an flight mode and the second mode comprises a maintenance mode.
