Abstract

A supervisor entity comprises an entity status module for maintaining status of its subordinate entities and updating the supervisor entity with status updates for itself and the subordinate entities. The entity status module comprises an entity status controller for receiving a status message from a first subordinate entity, a subordinate determination module for determining a second subordinate entity that is subordinate to the first subordinate entity, a status update module for updating the status of the second subordinate entity based on the received status message from the first subordinate entity, a status reporting module for reporting the updated status of the second subordinate entity to a supervisor entity and a status storage for storing the status of the second subordinate entity.

Claims

1. A computer-implemented method comprising:

determining, by an entity status controller in a first entity, an appropriate time for transmitting a status message reporting a status of the first entity to a second entity, wherein the first entity is a device subordinate to the second entity in a hierarchical network, the status of the first entity reflecting whether or not the first entity is active; and

transmitting, by an entity status reporting module in the first entity, the status message reporting the status of the first entity to the second entity, the status message including a list of identifications for active entities and a list of identifications for inactive entities, such that the second entity receives the status of the first entity and entities subordinate to the first entity in the hierarchical network,

wherein the appropriate time for transmitting the status message is a predetermined time after the first entity is initialized or a time after the status of the first entity has stabilized.

2. The method of claim 1 wherein the hierarchical network comprises at least four hierarchical levels of entities, and there is at least one hierarchical level, comprising one or more entities, subordinate to the first entity.

3. The method of claim 1 wherein the appropriate time is a configurable duration after the first entity is initialized.

4. The method of claim 1, wherein the hierarchical network comprises at least four hierarchical levels of entities, and there are at least two hierarchical levels, each comprising one or more entities, subordinate to the first entity.

5. The method of claim 1, further comprising:

receiving a signal from the second entity, the signal requesting the first entity to update the second entity with any status updates for entities subordinate to the first entity.

6. The method of claim 1, further comprising:

receiving, by the entity status controller, a first set of alive messages from an entity subordinate to the first entity;

determining, by the entity status controller, that the entity status controller is no longer receiving the first set of alive messages from the entity subordinate to the first entity; and

in response to the determining, transmitting, by the entity status reporting module, a second status message to the second entity indicating the entity subordinate to the first entity as inactive.

7. The method of claim 6, further comprising;

receiving, by the entity status controller, a second set of alive messages from the entity subordinate to the first entity;

in response to receiving the second set of alive messages from the entity subordinate to the first entity, determining, by the entity status controller, that the entity subordinate to the first entity is active; and

in response to determining that the entity subordinate to the first entity is active, transmitting, by the entity status reporting module, a third status message to the second entity indicating the entity subordinate to the first entity as active.

8. The method of claim 1, further comprising:

determining, by the entity status controller, a change in the status of the first entity; and

upon determining the change, transmitting, by the entity status reporting module, a status message reporting a subsequent status of the first entity to the second entity.

9. The method of claim 8, further comprising:

receiving, by the entity status controller, a signal from the second entity, the signal requesting a status update to the second entity.

10. The method of claim 8, further comprising:

determining, by the entity status controller, that the status of the first entity has stabilized; and

in response to determining that the status of the first entity has stabilized, transmitting, by the entity status reporting module, the status message reporting the status of the first entity to the second entity.

11. An entity status reporting apparatus in a first entity for reporting a status of the first entity to a second entity, the apparatus comprising:

an entity status controller in the first entity configured to determine an appropriate time for transmitting a status message reporting the status of the first entity to the second entity, wherein the first entity is a device subordinate to the second entity in a hierarchical network, the status of the first entity reflecting whether or not the first entity is active; and

an entity status reporting module in the first entity, communicatively coupled to the entity status controller, configured to transmit the status message reporting the status of the first entity to the second entity, the status message including a list of identifications for active entities and a list of identifications of inactive entities, such that the second entity receives the status of the first entity and all entities subordinate to the first entity,

wherein the entity status controller determines the appropriate time for transmitting the status message is a predetermined time after the first entity is initialized or a time after the status of the first entity has stabilized.

12. The entity status reporting apparatus of claim 11 wherein the hierarchical network comprises at least four hierarchical levels of entities in the hierarchical network each comprising one or more entities subordinate to the first entity.

13. The entity status reporting apparatus of claim 11 wherein the first entity has stabilized after a pre-configured amount of resources are available for executing system functions.

14. The entity status reporting apparatus of claim 11, wherein the hierarchical network comprises at least two hierarchical levels subordinate to the first entity, each level comprising one or more entities.

15. The entity status reporting apparatus of claim 11 wherein:

the entity status controller is further configured to receive a first set of alive messages from an entity subordinate to the first entity and determine that the entity status controller is no longer receiving the first set of alive messages from the entity subordinate to the first entity; and

the entity status reporting module is further configured to transmit a second status message to the second entity indicating the entity subordinate to the first entity as inactive in response to the entity status controller determining that the entity status controller is no longer receiving the first set of alive messages from the entity subordinate to the first entity.

16. The entity status reporting apparatus of claim 15 wherein:

the entity status controller is further configured to receive a second set of alive messages from the entity subordinate to the first entity and determine that the entity subordinate to the first entity is active in response to receiving the second set of alive messages from the entity subordinate to the first entity; and

the entity status reporting module is further configured to transmit a third status message to the second entity indicating the entity subordinate to the first entity as active in response to the entity status controller determining that the entity subordinate to the first entity is active.

17. The entity status reporting apparatus of claim 11 wherein:

the entity status controller is further configured to determine a change in the status of the first entity; and

the entity status reporting module is further configured to transmit a status message reporting a subsequent status of the first entity to the second entity upon the entity status controller determining the change.
