Carrier Grade NAT (CGNAT)

CGNAT – Feature Rich, Highly Secure, Elastic Scalability

Benu Networks CGNAT solution enables a smooth transition to IPv6 while allowing service providers to extend the breadth and life of their IPv4 networks. It is highly secure, has an extensive feature set and delivers an unprecedented level of scalability and performance.

Able to manage millions of concurrent sessions it enables carriers to manage both IPv4 and IPv6 infrastructure and content with ease.

As the network transitions to the future many service providers are turning to software-based solutions like Benu Networks’ CGNAT  which  provides more flexibility, lower cost, and higher scalability than a proprietary hardware-based approach.

Cloud-Native, Disaggregated, Software-Based

The solution is delivered from our SD-Edge Platform, a cloud-native, software-defined edge capable of delivering multiple network functions through software including CGNAT. It runs on x86-based commercial off the shelf (COTS) servers providing an unprecedented level of scalability and an unmatched economic model.

Adhering to the Broadband Forum’s TR-459 our architecture separates the control plane from the user plane (CUPS) with each running independently on high-performing commercial servers.

This enables our CGNAT gateways (user planes) to be geographically deployed throughout the network while the control plane can remain centralized for ease of management. This architecture delivers the following benefits:

• Frees service providers from being locked-in to vendor-proprietary hardware (and forced to replace when it is end of life)
• Distribute CGNAT user planes closer to the customer, enabling better scaling and faster break-out to the Internet.
• User planes and control planes are independently resilient and highly reliable.
• Centralized control plane simplifies management of IP address pools.
• Elastically scales control and user planes independently to match system sizing to service demands.
• Running on COTS x-86 server systems provides diversity in hardware supply chain, more competitive pricing, and better risk management in the event of a supply chain disruption when compared to proprietary hardware from a single vendor.

Deploy as a Standalone Gateway or Integrated with our BNG

As previously mentioned, our SD-Edge Platform is a cloud-native, software-defined edge capable of delivering multiple network functions through software. This means that in addition to delivering CGNAT it can also operate as a Broadband Network Gateway (BNG), Provider Edge Router (PE), (Trusted) Wireless Access Gateway, (T)WAG, Wireless Access Gateway (WAG), 5G Access Gateway Function (AGF), and Secure Access Service Edge (SASE).

This flexibility enables our CGNAT solution to be deployed as as standalone gateway or combined with BNG functionality thereby delivering a consolidated architecture for Internet access, further reducing the carrier’s total cost of ownership and providing tremendous operational efficiencies.
