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.

說明書

Example 24

The edge router of any combination of examples 22-23, wherein each vBNG instance of the one or more vBNG instances is further configured to: periodically advertise subscriber information to the BNG controller; and receive load balancing credit information from the BNG controller, wherein each vBNG instance of the one or more vBNG instances is configured to determine whether to receive the request to access service provider services based on the load balancing credit information.

Example 25

The edge router of any combination of examples 22-24, wherein each vBNG instance of the one or more vBNG instances is further configured to: periodically output network health information to the BNG controller.

Example 26

The edge router of any combination of examples 22-25, wherein each vBNG instance of the one or more vBNG instances is further configured to: receive configuration updates from a network instance and configuration manager (NICM) of the BNG controller; exchange security related information with the NICM of the BNG controller; receive updates from a unified network security management (UNSM) of the BNG controller; receive load balancing credit information from the BNG controller; or synchronize a local database with a network subscriber database (NSDB) of the BNG controller.

Example 27

The edge router of any combination of examples 22-25, wherein, to generate the vBNG instance, the BNG virtual machine manager is configured to generate the vBNG instance to recreate replayed subscriber information by a network subscriber database (NSDB) of the BNG controller.
