Simplify subscriber management with the flexible, highly scalable vBNG Evo™ Platform
Competition for broadband subscribers is fierce. As leading-edge technologies like ultra-broadband and Fixed Wireless Access (FWA) open the way to new markets—and pave the way for new, premium broadband services—the race to win new subscribers and keep the ones you have will intensify. That’s why today, more than ever, it’s essential for broadband providers to move quickly and nimbly to grow market share.
CommScope’s innovative virtual Broadband Network Gateway, the vBNG Evo™ platform, can help you easily and economically stay ahead of the competition. Featuring highly scalable user planes that you can add when and where you need them and control planes that support up to two million subscriber sessions each, the vBNG Evo platform’s disaggregated, software-based design supports more and varied features than chassis-based BNG, providing a competitive advantage in today’s fast-moving broadband environment .
With full support for today’s leading-edge broadband technologies—including GPON/XGS-PON, WiFi®, and Non-3GPP/3GPP FWA—the agile, flexible, and highly scalable vBNG Evo platform is an ideal choice for a variety of network designs. A single software solution that supports multiple deployment options, the vBNG Evo platform enables you to start “small” with a standalone, single-site cluster and scale to a nationwide, Kubernetes-based management solution in the cloud. It’s the ideal choice for virtualized subscriber management no matter what size network you operate.
Grow Revenue and Reduce Costs
Chassis-based BNGs limit your ability to add services and/or subscribers for a variety of reasons. Typically, a chassis-based BNG has limited scaling options per chassis, which hinders your ability to maximize your investment as you add subscribers. On the other hand, in some scenarios a chassis-based BNG may be underutilized due to its location and the number of subscribers it manages, which is also an inefficient use of funds. Moreover, chassis-based BNGs are limited to centralized deployments, which can increase the risk of service disruptions throughout the network and limit your network design and deployment options. Coupled with the fact that chassis-based BNGs provide no path to edge computing or cloud deployments—instead, they require costly hardware and software customization—and don’t support rapid rollouts of new services and features, it’s easy to see how chassis-based BNGs can limit revenue opportunities and inflate operating expenses.
Typical Chassis-based BNG Network Architecture
The vBNG Evo platform’s software-based approach, on the other hand, enables you to pay as you grow by adding user planes—used to manage subscribers—when and where you need them. This flexibility supports easily executable roadmaps for new service rollouts and subscriber growth. Combined with the platform’s ability to run off commercial off-the-shelf (COTS) servers—thereby eliminating the need for customized hardware—you can now have better control over capital and operational expenditures. And, at the same time, you’ll find new opportunities for increasing ARPU without being hindered by operational roadblocks you could encounter with chassis-based BNG technology.

Simplified, Flexible, and Agile Network Management
Simplicity plus flexibility plus agility equals speed: speedier new service deployment and integration, speedier network upgrade integration, and speedier scaling of new subscribers. With a vBNG platform deployment, you can accelerate business growth without cumbersome, disruptive, and costly hardware upgrades.
A vBGN Evo deployment can help you win the fight to obtain and keep high-speed data customers, with support for for 500 Gbps, scalable to Tbps, per server. This formula also means you can now retire legacy broadband equipment, including your Broadband Remote Access Servers (BRASs) and, of course, your hardware-based BNG chassis. Unlike hardware-based broadband network equipment, vBGN Evo technology scales data planes automatically according to the number of subscribers and throughput traffic. What’s more, the vBNG Evo platform features easily scalable user planes which you can add when and where you need them. This means you can both manage your current subscriber base more efficiently and more easily scale the network as you add new subscribers and services.
The vBNG Evo platform supports a best-in-class, NFV and disaggregated architecture based on the CUPS (Control Plane User Plane Separation) model, with a centralized control plane and distributed user planes. This design, which aligns Broadband Forum and Open Networking Foundation standards, mitigates the risk of service outages and costs less to deploy and manage than a chassis-based BNG. The highly flexible vBNG Evo platform supports a variety of network architectures, including cloud-native, Kubernetes container cloud-based networks. You can deploy the vBNG Evo platform in both centralized and distributed broadband networks according to your preferred network design.
Another advantage? The vBNG Evo platform has far greater service agility than chassis-based BNGs. vBNG Evo user planes, for example, have superior and more robust N:M (many to many) redundancy capabilities, including geo redundancy, to ensure seamless operational continuity across multiple locations in the event of a user plane failure. Unlike chassis-based BNGs, the vBNG Evo platform’s software-based architecture is also more agile when it comes time for you to initiate upgrades, deploy new services in your network, and scale to accommodate new subscribers.
The vBNG Evo platform is also significantly more flexible than previous generation hardware. For example, the platform’s disaggregated design enables you to choose where you distribute data planes—including the option to move data planes closer to subscribers--while retaining centralized control over control planes. Since the two planes operate independently of each other, you can also scale each plane based on your network requirements while retaining independent control over both. This flexibility supports a variety of deployment scenarios supported by the vBNG Evo platform’s Application Programming Interface (API), including:
- A centralized, same-server control architecture located in an office or data center
- A multiple server architecture
- A multiple location architecture, with centralized control and/or data plane(s) deployed closer to subscriber locations in remote central offices
Enhanced, Optimized Network Performance
|
The vBNG Evo platform’s feature-rich control and user planes can enhance quality of service (QoS) and the overall user experience. Its elastic scaling—which leads to better time to service for subscribers—supports per-subscriber QoS, enabling you to tailor network policies and service configurations on an individual basis. Now, instead of being locked into global policies that may satisfy one group of subscribers at the expense of another, you can customize your network resources to support different subscribers’ needs and expectations. Additionally, the vBNG Evo platform supports captive portals, which enable you to create custom login/splash pages for specific content and further personalize the user experience. Other features can also enhance and optimize the overall performance of your broadband network. The vBNG Evo platform supports policy-based routing, for example, which enables you to route network traffic based on specific conditions that are defined by your network administrator. You can also use the policy-based routing feature to route information packets to and from different networks and establish advanced security protocols to maintain greater control over network operation. The vBNG Evo platform utilizes DHCP relay, which can help to simplify network administration and eliminate the need for a DHCP server on every segment. Additionally, the vBNG Evo platform supports Carrier Grade Network Address Translation (CGNAT), enabling you to aggregate multiple private IPv4 addresses into fewer public ones. Featuring more flexibility than hardware-based CGNAT operation, the vBNG Evo platform CGNAT function supports 64 million sessions per user plane. The vBNG Evo platform also features a Wireless Access Gateway (WAG), which virtualizes access and services for your wireless customers. The vBNG Evo WAG can assume the functions performed by a chassis-based Wireless Access Gateway (WAG) in traditional broadband networks. |
