Virtual BNG

Virtual Broadband Network Gateway
Subscriber Management for the Software-Defined Era

New: Download our free white paper, Carrier Networks Evolve: vBNGs Provide Scale, Reduce Costs

Annual global IP traffic is exploding. Subscriber bandwidth demand is being fueled by more connected devices, cloud computing, and video streaming. These increasing traffic volumes are creating challenges since legacy BNGs are difficult to scale, expensive, and inflexible.

vBNG was developed to scale rapidly and efficiently with data plane optimizations that deliver near line-rate performance. Patented optimizations include packet processing techniques combined with our best-in-class implementation of DPDK and PCI pass-through on Intel NICs.

netElastic vBNG supports more subscribers and more capacity per node, with up to 128,000 subscribers and 80Gbps throughput on a single node. netElastic also supports incremental data plane scale-out for larger, multi-node deployments up to 300Gbps and beyond.

vBNG supports carriers’ network architectures and protocols, including IPv4, IPv6, MPLS, OSPF, CGNAT, L2/L3/VPN, VxLAN, IPoE, and PPPoE.
The advanced subscriber management capabilities with vBNG help service providers deliver differentiated service offerings (and better user experiences) for residential, MDU, and small business customers. Advanced subscriber management also lowers operational costs and speeds time to market for new services by providing flexibility for access, authentication, and QoS offerings.

vBNG supports popular CLI emulations to leverage your teams’ existing experience and knowledge. Integrated support for NETCONF and YANG models enables orchestration and management automation for additional operational savings.

Running on x86-based commodity hardware, vBNG delivers flexibility and cost savings, while also supporting growing carrier virtualization initiatives, such as CORD.

netElastic vBNG delivers market-leading performance and scalability in a virtualized subscriber management platform. vBNG provides advanced subscriber value while delivering CAPEX and OPEX savings.
