Abstract

A network of nodes and connections is provided, each connection connecting two nodes. Operating a first node in the network includes detecting a change in a node connected to the first node, identifying that the number of nodes connected to the first node with the detected change is above a predetermined threshold, and executing the detected change at the first node and/or propagating the detected change to one or more nodes connected to the first node that do not have the detected change.

Claims

1. A first node in a network of nodes and connections, each connection connecting two nodes, the first node comprising a processing device arranged to:

detect, in response to a configuration change, a different configuration in a node connected to the first node;

identify a number of nodes, from a plurality of nodes connected to the first node, that include the different configuration;

determine that the identified number of nodes exceeds a predetermined threshold; and

instruct each of the plurality of nodes to implement the different configuration in response to the determination.

2. The node according to claim 1 wherein the processing device is further arranged to:

propagate the different configuration to one or more nodes connected to the first node that do not have the detected change.

3. The node according to claim 2, wherein the processing device is further arranged to designate the first node as a gateway node and the processing device is arranged, when propagating the different configuration to one or more nodes connected to the first node that do not have the different configuration, to propagate the different configuration to one or more other gateway nodes.

4. The node according to claim 2, and further comprising a storage device arranged to store a node group membership list defining a group of nodes comprising one or more nodes, and wherein the processing device is arranged, when propagating the different configuration to one or more nodes connected to the first node that do not have the different configuration, to propagate the different configuration to the nodes defined in the node group membership list.

5. The node according to claim 2, and further comprising a storage device arranged to store one or more rules, and wherein the processing device is further arranged to ascertain whether the different configuration conflicts with the one or more rules and only propagating the different configuration if the different configuration does not conflict with the one or more rules.

6. The node according to claim 1, and further comprising a storage device arranged to store one or more rules, and wherein the processing device is further arranged to ascertain whether the different configuration conflicts with the one or more rules and only executing the different configuration if the different configuration does not conflict with the one or more rules.

7. The node according to claim 1, wherein the processing device is arranged, when detecting the configuration change in the node connected to the first node comprise instructions for receiving a notification from the node detailing the different configuration.

8. A computer program product stored on a computer readable storage device for operating a first node in a network of nodes and connections, each connection connecting two nodes, wherein the product comprises instructions for:

detecting, in response to a configuration change, a different configuration in a node connected to the first node;

identifying a number of nodes, from a plurality of nodes connected to the first node, that include the different configuration;

determining that the identified number of nodes exceeds a predetermined threshold; and

instructing each of the plurality of nodes to implement the different configuration in response to the determination.

9. The computer program product according to claim 8, wherein the product further comprises instructions for:

propagating the different configuration to one or more nodes connected to the first node that do not have the detected change.

10. The computer program product according to claim 9, and further comprising instructions for storing a node group membership list defining a group of nodes comprising one or more nodes, and wherein the instructions for propagating the different configuration to one or more nodes connected to the first node that do not have the different configuration comprise instructions for propagating the different configuration to the nodes defined in the node group membership list.

11. The computer program product according to claim 9, and further comprising instructions for designating the first node as a gateway node and wherein the instructions for propagating the different configuration to one or more nodes connected to the first node that do not have the different configuration comprise instructions for propagating the different configuration to one or more other gateway nodes.

12. The computer program product according to claim 9, and further comprising instructions for storing one or more rules, ascertaining whether the different configuration conflicts with the one or more rules and only propagating the different configuration if it does not conflict with the one or more rules.

13. The computer program product according to claim 8, and further comprising instructions for storing one or more rules, ascertaining whether the different configuration conflicts with the one or more rules and only executing the different configuration if the different configuration does not conflict with the one or more rules.

14. The computer program product according to claim 8, wherein the instructions for detecting the configuration change in the node connected to the first node comprise instructions for receiving a notification from the node detailing the different configuration.
