Abstract

A closed loop system is described for enhanced adaptive network capabilities in support of workflow missions. Multiple workflow-locked loops with different sampling rates are employed. A faster, lower loop is employed to gather data from the field and deal with network level exceptions such as faults, fades, and changing conditions. A slower, upper loop is employed to handle mission level exceptions. The result is a system capable of integrating management of multiple workflow missions, including reallocation of resources in response to changes in mission goal statements and network resource availability.

Claims

1. An apparatus for facilitating adaptation of at least one software-controllable communications network comprising:

a translation module, the translation module operative to translate at least one mission goal statement to a policy statement;

a controller, the controller operative in response to the policy statement to configure the software-controllable network;

a first workflow-locked loop between the translation module and the controller, the first workflow-locked loop processing mission level exceptions based on information from the controller, the first workflow-locked loop responsive to the mission level exceptions to change at least one policy statement; and

a second workflow-locked loop between the controller and the software-controllable network, the second workflow-locked loop gathering data from the field and processing network level exceptions based on the data gathered from the field, the second workflow-locked loop responsive to the network level exceptions to cause the controller to reconfigure the software-controllable network.

2. The apparatus of claim 1 wherein the first workflow-locked loop has a response time which differs from that of the second workflow-locked loop.

3. The apparatus of claim 2 wherein the first workflow-locked loop has a response time which is slower than that of the second workflow-locked loop.

4. The apparatus of claim 1 wherein there are a plurality of missions, and for each mission there is a controller that configures the software-controllable network to support a workflow defined for that mission.

5. The apparatus of claim 4 wherein each controller is operative to prompt its software-controllable network to provide information regarding network level exceptions.

6. The apparatus of claim 5 wherein each controller is operative to filter from the information those exceptions which will be adequately remedied by the software-controllable network.

7. The apparatus of claim 6 wherein an indication of the remaining information is provided to other controllers.

8. The apparatus of claim 6 wherein an indication of the remaining information is provided to the translation module.

9. A method for facilitating adaptation of at least one software-controllable communications network, the method comprising the steps of:

translating, with a translation module, at least one mission goal statement to a policy statement;

in response to the policy statement, configuring the software-controllable network with a controller;

processing mission level exceptions via a first workflow-locked loop between the translation module and the controller to change at least one policy statement; and

processing network level exceptions and gathering data from the field via a second workflow-locked loop between the controller and the software-controllable network, the network level exceptions to cause the controller to reconfigure the software-controllable network.

10. The method of claim 9 including the further step of configuring the first workflow-locked loop with a response time which differs from that of the second workflow-locked loop.

11. The method of claim 9 including the further step of configuring the first workflow-locked loop with a response time which is slower than that of the second workflow-locked loop.

12. The method of claim 9 wherein there are a plurality of missions, and including the further step of assigning a controller to each mission to configure the software-controllable network to support a workflow defined for that mission.

13. The method of claim 12 including the further step of prompting, with each controller, its respective software-controllable network to provide information regarding network level exceptions.

14. The method of claim 13 including the further step of each controller filtering from the information those exceptions which will be adequately remedied by the software-controllable network.

15. The method of claim 14 including the further step of providing an indication of the remaining information to other controllers.

16. The method of claim 14 including the further step of providing an indication of the remaining information to the translation module.
