A central management component deployed in a cluster of broadband network gateways (BNGs) balances load among subscribers through the cluster by monitoring subscriber states comprising usage of the BNGs based on load parameters to detect an overload condition on any BNG. In the event of an overload condition, the component performs a horizontal sharding operation to move at least some access load from the overloaded BNG to an underutilized BNG. Sharding separates a large group of BNGs into smaller and more numerous BNGs by reassigns one or more subscribers among the gateways. A load balancer applies rules to re-direct traffic based on a defined load balancing rule using one of: preference, present load, proximity, and operating characteristic.
