Although FIG. 2 described BNG controller 35 in operation with virtual vBNG instances, in some examples, BNG controller 35 may operate with physical BNGs or a combination of physical BNGs and virtual vBNG instances. For example, NRM 41 may actively monitor resources across physical BNGs. In some examples, NLB 47 may load balance physical BNGs. In some examples, NRM 41 may be aware of subscriber related resource utilization of physical BNGs. In some examples, NRM 41 may monitor the health of each physical BNG. In some examples, SA 51 may collect subscriber data and information for physical BNGs. For example, UNSM 53 may manage network wide distributed denial-of-service (DDoS) detection and protection for physical BNGs.
