摘要

A broadband network gateway (BNG) controller is described that includes a network subscriber database (NSDB) and one or more core applications. The NSDB is configured to store vBNG instance information for one or more subscriber devices. The vBNG instance information specifies vBNG instances operable by one or more edge routers. The vBNG instances are configured to receive requests to access service provider services from the one or more subscriber devices and to selectively authenticate the one or more subscriber devices for network services based on authentication information included in the requests to access services provider services. The one or more core applications include a network instance and configuration manager (NICM). The NICM is configured to modify the vBNG instance information at the NSDB to include an additional vBNG instance and to output, to an edge router, an instruction to generate the additional vBNG instance at the edge router.

NRM 441 outputs, to NICM 445, a request to clean up vBNG 1 457 (416). Said differently, when health data for vBNG 1 457 is not received within the threshold time, NRM 441 outputs, to NICM 445, an instruction to destroy vBNG 1 457. NICM 445 outputs, to vBNG 1 457, an instruction to destroy vBNG 1 457 (418). Said differently, NICM 445 outputs an instruction, to an edge router that provisioned vBNG 1 457, to delete vBNG 1 457 in response to receiving the instruction to destroy vBNG 1 457 from NRM 441. In this example, vBNG 1 457 and/or a BNG virtual machine manager for vBNG 1 457 receives the instruction to destroy vBNG 1 457 and destroys the particular vBNG instance.

NRM 441 notifies NLB 447 to recompute the load (420). Said differently, NRM 441 outputs, to NLB 447, an instruction to recompute load balancing for vBNG N+1 461N. In this example, NLB 447 outputs a load balancer credit to vBNG N+1 461N in response to the instruction to recompute load balancing for vBNG N+1 461N. As shown in FIG. 5, when vBNG 1 457 does send a heartbeat message in last ‘n’ seconds, NRM 441 increments a heartbeat fail count.

FIG. 6 is a flowchart illustrating an example mode of operation of a BNG controller in accordance with techniques described herein. FIG. 6 is discussed with respect to FIGS. 1-2 for exemplary purposes only.
