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(shuō)明書(shū)

FIG. 1 is a block diagram illustrating an example network system 10 in accordance with techniques described herein. As shown in the example of FIG. 1, network system 10 includes a service provider network 20 coupled to a public network 22. Service provider network 20 operates as a private network that provides packet-based network services to subscriber devices 18A, 18B, 18C (collectively, “subscriber devices 18”).

The elements of network system 10 may support any one or more of a variety of protocols, such as Internet Protocol (IP), Frame Relay, Asynchronous Transfer Mode (ATM), Ethernet, Point-to-Point Protocol (PPP), Point-to-Point Protocol over Ethernet (PPPoE), GPRS tunneling protocol (GTP), Dynamic Host Configuration Protocol (DHCP), Layer 2 Tunneling Protocol (L2TP), and virtual local area network (VLAN)-related protocols, among others. Using any one or more of these protocols, any of subscriber devices 18 may present authentication credentials to edge routers 30-32 to request access to a service provider network 20 service. For example, subscriber device 18A may broadcast credentials, such as a username and password, to edge router 30 to request access to a service provided by service provider network 20. Subscriber devices 18 may broadcast credentials using, for instance, a PPPoE Active Discovery Initiation (PADI) packet to edge routers 30-32.
