Virtual BRAS and CG-NAT solutions

Software-based BRAS

The virtual BRAS is a flexible and scalable solution for carriers. It is implemented in the ISP network with the use of any available hardware and is connected with the billing system via RADIUS protocol in the L3 (IPoE) or L2 (DHCP, ARP, PPPoE) modes with VLAN and Q-in-Q support.

The software-based BRAS makes it possible to improve the Quality of Service (QoS) and get additional statistics from the QoE analytics module.


BRAS solution can be combined with the CG-NAT when using the same server. CG-NAT significantly expands existing networks’ capacities, prolongs usage of IPv4 addresses, and simplifies the migration to IPv6 addresses by supporting the v4/v6 Dual-Stack. The solution supports Full-Cone and Symmetric NAT, NAT44/NAT444, ALG, Hairpinning technologies.



Affordable and future-proofing network

Deployment flexibility

Simplified management with GUI

IPv6-ready solution

Real-time subscriber statistics

NAT-logs for the regulatory compliance

What do you get?

Reliable working infrastructure

Get rid of the vendor-lock and obsolete equipment. The virtual BNG will replace the disparate system of Mikrotik/Cisco/Huawei/etc servers.


The network core is easy to manage: several devices are combined into one, performing BRAS, CG-NAT, DPI, QoS, QoE, and others.

Affordable solution

We suggest you pay only for the number of real subscribers and scale up easily when you need to!

Customers Reviews

We used to have SCE, CGN. Now we have two “boxes” that can reduce all processes to a minimum set of actions. Thanks to VAS Experts engineers for providing fast and dynamic work.
"After understanding how the solution works, implementation was easy. Thanks to the VAS Experts engineers and developers for the patient and thorough explanation of the BNG principles and tips on how best to configure the functionality."
The cost of Stingray solution is lower than the new devices and the deployment was very fast. We didn’t face any problems while configuring. We are planning to expand the network next year, whereas the positive results of the VAS Experts software implementation leave no doubt that the DPI, BNG and CG-NAT manufacturer replacement is not needed.
