Dynamically selecting an optimal path to a remote node
In a multi-cell system, a dynamic adjustment of a workload of a data path between multiple cells of the system may be preferred to eliminate system latencies during operation of the system. The dynamic adjustment may include monitoring a workload, or an amount of data traffic, of a data path and determining if the monitored workload of the data path exceeds a predetermined workload threshold. If the workload threshold is exceeded, the dynamic adjustment of the workload of the data path may include transferring a portion of data from the monitored data path to another data path that is also connected to the same cells as the monitored data path. The transfer of data may be to a previously-existing data path that has capacity for the data, to a newly-created data path, or to both a previously-existing data path and a new data path.

an information retrieval component for receiving monitored workload information between a first cell and a second cell;
a determination component for deciding to dynamically readjust the monitored workload between the first cell and the second cell; and
a dynamic readjustment component for dynamically readjusting the monitored workload between the first cell and the second cell and for creating at least a new path.
17 . The workload management controller of claim 16 , wherein the information retrieval component receives the monitored workload information between the first cell and the second cell from one of a first workload monitor of the first cell and a second workload monitor of the second cell.
