In the example of FIG. 3, all the vBNG instances are running at close to full capacity. That is, for example, the existing vBNG instances are running out of resources and/or the number of subscribers logged in are nearing the capacity of the vBNG instances. In such instances, an administrator may want to spawn a new instance of vBNG to take up the new subscribers. In the example of FIG. 3, instead of manually creating the guest instance and then adding configuration, BNG controller 35 may dynamically create a guest instance and then adding a configuration for the guest instance. That is, for example, NRM 241 may be configured to determine a capacity and action based on the percentage of usage and, if the configured action is to create guest instance, NRM 241 may trigger NICM 245 to create a new instance as described in the following.
Initially, client 258 outputs broadcasts packet and a client subscriber login (204). In the example of FIG. 3, vBNG N 257 has an “out of resources” condition. For example, vBNG N 257 may lack CPU availability, memory, bandwidth, control packet response times, inflight login/logouts (e.g., event rate analyzer), critical management queues, and other system resource aspects.
