In two previous articles, we discussed why interest in BNG and RADIUS-based provisioning is growing and what makes COS’s solution unique. In this article, we will take a deeper look at the key factors to consider when selecting a RADIUS solution.

When implementing a BNG in your network, you will need to decide on a RADIUS solution and how to set up the database. This decision is far from straightforward and can be complex, which is why we want to provide guidance here.

At COS, we have encountered several different methods for implementing RADIUS provisioning. Since this solution plays a crucial role in network reliability, it is well worth investing time in making an informed decision. Naturally, your specific circumstances will determine which solution best fits your network, but below are our general recommendations.

The following solutions are based on FreeRADIUS and PostgreSQL but are similar for MariaDB/MySQL.

Three RADIUS Authentication & Authorization Solutions with FreeRADIUS

Option 1: The Simplest Setup – No Redundancy

  • 1 VM (Virtual Machine) with FreeRADIUS
  • 1 VM with the database, with automatic backup/export

Since virtual servers are used, it is easy to perform backup/restore/replication, create snapshots before updates, and similar tasks. In this scenario, the underlying virtualization platform (e.g., VMware) minimizes downtime compared to physical machines. This setup is straightforward and works well for less critical implementations and lab environments.

Option 2: Redundancy via Replication

  • 2 VMs with FreeRADIUS
  • 2 VMs for the database (1 primary, 1 secondary/standby)

FreeRADIUS must be configured to recognize both databases (primary and secondary) so that it automatically switches to the secondary if the primary stops responding. To promote the secondary database to primary automatically, additional configuration and usually an extra VM (quorum) are required. Otherwise, this must be done manually. This setup is a good balance between complexity and reliability.

Option 3: Redundancy via Clustering

  • 2 VMs with FreeRADIUS
  • 2 VMs with the database in cluster mode, either active-passive (the passive takes over if the active fails) or active-active (both share the load)

The clustering setup is significantly more advanced than the replication approach in Option 2 but enables even higher uptime. The two RADIUS servers connect to an IP address representing the cluster. In active-active mode, both database VMs are operational simultaneously, sharing the load. Failover occurs automatically without manual intervention. However, this is the most complex setup and requires advanced database expertise for monitoring and maintenance. It is best suited for large operators with the highest availability requirements and in-house expertise to manage this setup.

RADIUS Accounting

Collecting RADIUS Accounting data—detailed statistics and usage information—can be demanding and should be handled by a separate RADIUS server with its own database. The redundancy options described above focus on managing Authentication and Authorization functions.

In our previous article, which you can read here, we discussed how Active Ethernet networks can be modernized with BNG (Broadband Network Gateway) and RADIUS provisioning, simplifying operations and increasing scalability. However, not all BNG and RADIUS implementations are the same—and this is where COS Systems stands out. Our solution is designed to provide higher operational reliability, easier management, and better control while being flexible enough to fit different network models.

What Makes COS Systems’ Solution Unique?

COS Systems has developed a flexible and automated RADIUS integration to manage BNGs, eliminating many of the challenges faced by previous implementations. Here are some of the key advantages:

  • Simplified Configuration and Management – Our solution requires minimal manual configuration, making network deployment and maintenance quick and easy.

  • All Data in One Place – Provisioning parameters and customer information are centrally managed within COS Business Engine instead of being scattered across different systems. This means there’s no need to log into the RADIUS database directly to view and manage provisioning attributes.

  • Robust Backup and Recovery – Since all data is stored in the COS platform, an up-to-date copy of the network’s provisioning information is always available. If anything happens, the system can be easily resynchronized and restored! Additionally, since COS Business Engine itself is backed up, this provides multiple layers of security.

  • Monitoring – Our solution not only monitors RADIUS itself but also the underlying database, providing better visibility and insight for operators.

  • Seamless Migration from Legacy Solutions – If you already have information on where customers are connected (e.g., switch ports), we can build a RADIUS database to facilitate an easier transition to BNG provisioning.

Support for Different BNG Provisioning Models

Our solution is flexible and supports multiple established BNG provisioning models, including:

  • Centralized BNG – A single BNG handling all traffic and provisioning from a central location.

  • Distributed BNG – Multiple BNG units sharing the load and creating redundancy.

  • Virtual BNG (vBNG) – Software-based BNG that can run virtually or on dedicated hardware, such as solutions from our partner netElastic.

Technical Enhancements in Our Implementation

We have also made key technical improvements compared to older BNG and RADIUS implementations:

  • Support for provisioning via RADIUS using a combination of users, groups, and user profiles.

  • Pre-built integrations for MariaDB/MySQL and PostgreSQL.

  • Support for both modern WireGuard and traditional IPSec-based VPNs.

  • Management of RADIUS attributes, operators, and values directly in COS Business Engine’s web interface.

  • Support for various VLAN schemes, including those using pseudo-wires.

  • Ability to resynchronize RADIUS data in case of catastrophic failure.

  • Full compliance with the FreeRADIUS standard schema, making FreeRADIUS updates simpler and less risky.

A Smooth, Robust, and Future-Proof Solution

With our BNG and RADIUS implementation, you get a reliable and flexible solution that makes network management easier. Our centralized management, automated provisioning, and monitoring give operators and network owners better control and lower operational costs. At COS, we’re ready to help you transition to BNG provisioning in a cost-effective way.

Network owners are facing an exciting transformation. Thanks to recent price reductions in Broadband Network Gateway (BNG) solutions, opportunities that were once reserved for larger operators are now within reach for small and mid-sized network owners. Today, these investments are not only justifiable for streamlining operations but also for enabling the rapid deployment of new services and technologies.

RADIUS and BNG – An Efficient Path Forward

Traditional provisioning of Active Ethernet networks often requires manual or semi-automated provisioning of network switches. Many networks consist of switches from multiple hardware vendors, demanding deep technical expertise to ensure secure and scalable operations. By implementing BNG solutions, provisioning can be simplified, automated, and centralized. This is achieved by configuring the access portion of the network statically, allowing all service changes to be managed centrally via the BNG—eliminating the need for local reconfiguration of switches.

Provisioning is controlled using RADIUS, a standardized and proven protocol for centralized authentication, authorization, and accounting (AAA). To fully automate this process, integration with a BSS/OSS system—such as COS Business Engine—is required.

Key Benefits of RADIUS and BNG Provisioning

  • Reduced Complexity – Enables the use of simpler and more cost-efficient access switches.
  • Improved Reliability and Easier Troubleshooting – The static access layer allows for quicker problem identification.
  • Enhanced Security and Policy Management – RADIUS centrally handles authentication, authorization, and accounting (AAA), while BNG supports Quality of Service (QoS) and policy-based traffic control.
  • Scalability and Future-Proofing – The solution works equally well for both small and large networks.
  • Flexible Service Delivery and Integration – Changes can be implemented without manual intervention.
  • Free Seating – Simplifies customer equipment setup and reduces support calls since the customer’s device can connect to any port without requiring predefined settings. A practical example is that a customer’s IP telephony service will work regardless of which port their device is connected to.

Understanding Demand Aggregation in Fiber Broadband and Its Role in COS Business Engine

The success of a fiber broadband network relies on more than just deploying infrastructure—it depends on ensuring that there is enough demand to make the investment viable. This is where demand aggregation comes into play. By gathering and analyzing interest from potential customers before building out the network, broadband providers can optimize deployment, reduce financial risk, and accelerate take-up rates.

What Is Demand Aggregation in Fiber Broadband?

Demand aggregation is the process of collecting and analyzing consumer interest in fiber broadband before network construction begins. This approach helps service providers:

  • Identify areas with the highest demand
  • Prioritize network rollout to maximize return on investment (ROI)
  • Reduce financial and operational risks by ensuring there are enough subscribers
  • Engage communities early, fostering awareness and commitment to fiber adoption

Instead of deploying fiber and hoping customers will sign up, demand aggregation ensures that ISPs and network operators invest in locations where there is a proven interest.

How Demand Aggregation Works in COS Business Engine

COS Business Engine provides an advanced and automated approach to demand aggregation, making it easier for fiber network operators to gauge interest, manage pre-signups, and strategically plan their network build. Here’s how it works:

1. Capturing Customer Interest

The process begins by enabling potential customers to express interest in fiber broadband through an online registration form in the customer portal. This portal allows residents and businesses to sign up and indicate their level of commitment, whether it’s simply interest or a pre-order.

2. Geographic Demand Mapping

COS Business Engine segments the network area into demand zones like neighborhoods or towns. The platform then tracks how many residents in each zone have registered their interest, providing real-time insight into the highest demand.

3. Setting Take-Rate Thresholds

Network operators can set a minimum take-rate threshold for each area to ensure a viable deployment. For example, if a provider requires a 40% commitment level before proceeding, COS Business Engine will track progress toward that goal and notify stakeholders when the target is met.

4. Automated Customer Engagement

Through the system’s built-in communication tools, potential customers receive automated updates, marketing materials, and calls to action, encouraging them to complete their sign-up. This engagement helps drive momentum and increase participation rates.

5. Decision-Making and Rollout Planning

Once a neighborhood or zone reaches the required take rate, COS Business Engine flags it as ready for deployment. The system can then automatically transition pre-signups into active orders, streamlining the next steps for network construction and service activation.

6. Post-Deployment Conversion and Service Activation

After installing fiber, COS Business Engine plays a crucial role in converting interested customers into paying subscribers. The system ensures a seamless transition from demand aggregation to order fulfillment and service provisioning.

The Benefits of Demand Aggregation with COS Business Engine

  • Optimized Network Investments: Focus resources on areas with proven demand, reducing financial risk.
  • Faster Market Entry: Prioritizing high-interest zones speeds up customer acquisition and revenue generation.
  • Higher Take Rates: Engaging communities early leads to more substantial adoption rates once the network goes live.
  • Automated and Efficient Process: COS Business Engine eliminates manual tracking, providing a seamless, data-driven approach.

Demand aggregation is a critical strategy for ensuring a fiber broadband network’s financial and operational success.
