Abstract

A source communication device comprises a cluster manager to group destination device connections into a plurality of performance clusters. The cluster manager then causes a synchronization mechanism to be generated for each performance cluster. Each synchronization cluster can then allow data to be optimally shared between the source device and destination devices within a given cluster.

Claims

1. A device, comprising:

a processor;

a memory unit; and

a cluster manager configured to;

insert one or more removed destination devices, which have been removed from one or more corresponding performance clusters, back into the one or more corresponding performance clusters based on the one or more removed destination devices responding to an update request before an expiration of a timeout threshold and a recent average latency of the one or more removed destination devices reaching a threshold value for insertion back into the one or more corresponding performance clusters;

determine subsets of connections from a set of connections, wherein each connection in each subset has similar performance capabilities with the other connections in the same subset; and

detect a change in performance capabilities for one of the plurality of connections and to assign a connection for the one of the plurality of connections to another performance cluster based on the change in performance capabilities.

2. The device of claim 1, wherein each of a plurality of synchronization mechanisms is configured to determine at least one of client service and resource priorities, determine performance similarities for a plurality of connections made via a plurality of connection interfaces, and group the plurality of connections into performance clusters based on the determined performance similarities and the determined client service and resource priorities.

3. The device of claim 2 wherein the plurality of synchronization mechanisms is coupled with the plurality of connection interfaces, and wherein the cluster manager is configured to assign a synchronization mechanism to each of the performance clusters.

4. The device of claim 3, wherein each of the plurality of synchronization mechanisms is configured to provide computations and protocols needed to communicate data over the plurality of connections.

5. The device of claim 4, further comprising a source data buffer configured to store data, and wherein the source device is configured to share the data stored in the source data buffer with the plurality of destination devices interfaced with the source device via the plurality of connection interfaces.

6. The device of claim 2 wherein the cluster manager is configured to assign a synchronization mechanism to each of the performance clusters.

7. The device of claim 6, wherein each of the plurality of synchronization mechanisms is configured to provide computations and protocols needed to communicate data over the set of connections.

8. The device of claim 1, wherein the cluster manager is configured to create at least one of:

fewer performance clusters when it is determined that resource priorities are a priority; and

more performance clusters, when it is determined that client service is a priority.

9. The device of claim 1, wherein the cluster manager is configured to remove the one or more destination devices, that do not respond within the timeout threshold, from their performance clusters.

10. The device of claim 1, wherein the cluster manager is further configured to detect a new connection, determine a performance of the new connection, and add the new connection to a performance cluster based on the performance of the new connection.

11. The device of claim 1 wherein each of the subsets are grouped in a distinct performance cluster.

12. A system, comprising:

a processor and a memory unit; and

a cluster manager configured to;

insert one or more removed destination devices, which have been removed from one or more corresponding performance clusters, back into the one or more corresponding performance clusters based on the one or more removed destination devices responding to an update request before an expiration of a timeout threshold and a recent average latency of the one or more removed destination devices reaching a threshold value for insertion back into the one or more corresponding performance clusters, and

determine subsets of connections from a set of connections, wherein each connection in each subset has similar performance capabilities with the other connections in the same subset,

wherein the cluster manager is further configured to;

assign the connection to another performance cluster based on the change in performance capabilities.

13. The system of claim 12, further comprising a plurality of synchronization mechanisms, wherein the cluster manager is configured to assign a synchronization mechanism to each of the performance clusters.

14. The system of claim 13 wherein each of the plurality of synchronization mechanisms is configured to provide computations and protocols needed to communicate data over the set of connections.

15. The system of claim 12 wherein each of the subsets are grouped in a distinct performance cluster.

16. The system of claim 15, further comprising an intermediate source device and an intermediate source data buffer configured to store data, and wherein the intermediate source device is configured to share the data stored in the source data buffer with the plurality of destination devices.

17. The system of claim 12, wherein the performance clusters include at least one of:

a high performance cluster;

an intermediate performance cluster; and

a low performance cluster.

18. The system of claim 12, wherein similarity in the performance capabilities for each subset of connections is determined by at least one of:

similarity in connection bandwidth;

similarity in connection security; and

similarity in connection error rate.

19. The system of claim 12, wherein the cluster manager is further configured to detect a change in performance capabilities for a connection in one performance cluster.

20. A method, comprising:

inserting one or more removed destination devices, which have been removed from one or more corresponding performance clusters, back into the one or more corresponding performance clusters based on the one or more removed destination devices responding to an update request before an expiration of a timeout threshold and a recent average latency of the one or more removed destination devices reaching a threshold value for insertion back into the one or more corresponding performance clusters;

determining, by a cluster manager, subsets of connections from a set of connections, wherein each connection in each subset has similar performance capabilities with the other connections in the same subset; and

assigning, by the cluster manager, the connection to another performance cluster based on the change in performance capabilities.
