Abstract:
1. A method comprising: generating node utilization data for each of a plurality of aggregation nodes; generating a node utilization list responsive to the node utilization data; activating a first aggregation node from the plurality of aggregation nodes responsive to the node utilization list; accepting a subscriber session in the first aggregation node after activating the first aggregation node; deactivating the first aggregation node after accepting a predetermined number of other subscriber sessions in the first aggregation node responsive to the node utilization list so that the first aggregation node will not accept new subscriber sessions; generating node utilization data of the first aggregation node after deactivating the first aggregation node; activating a second aggregation node from the plurality of aggregation nodes responsive to the node utilization list; deactivating the second aggregation node after accepting a predetermined number of other sessions in the second aggregation node responsive to the utilization list so that the second aggregation node will not accept new subscriber sessions; generating node utilization data of the second aggregation node after deactivating the second aggregation node; and creating a new node utilization list when the second aggregation node is a last node listed in the node utilization list.
