BNG/BRAS — a solution for broadband providers
BNG/BRAS for broadband access providers
Control subscribers' connection to the Internet via IPv4/IPv6 protocols
Apply polysynching
Improve quality of service (QoS)
Improve the quality of user experience (QoE)
When combining different types of networks and changing access technology, there is a need to provide services for all types of subscriber device authorization on the same BNG
- PPPoE
- DHCP
- VMware SDDC Manager for Cloud Foundation
- IPoE
- Static
- Vmware vRealize Network Insight
Benefits of BNG/BRAS from VAS Experts
Support for virtual environments
Scalability
Two control options
High fault tolerance
Reduce costs
You can choose any equipment you want - no manufacturer-specific requirements
The solution cannot become obsolete and require replacement - software licenses do not have an EoL
Pricing is based on bandwidth with no limit on number of subscribers
We provide direct contact with our developers - the system can be modified to solve a non-standard problem
Easy to deploy
BRAS/BNG software can be installed on any server hardware that meets the minimum requirements. Also, the hardware and software platform can be purchased from our partners.
Usually system deployment takes about 2 weeks when the server, network architecture and other preparatory works are ready. VAS Experts engineers help to implement the software and integrate it with the billing system. The operator’s engineers are provided with standardized methods for managing all functions, training and an accessible graphical interface.
Provider problems that BNG solves
As an ISP’s network grows, its performance and bandwidth resources are exhausted, making administration more complex, increasing energy bills and requiring more space to install equipment
All hardware eventually becomes unusable. The problem may be an expired support period or if the developer is unable to help repair the equipment
Large and mid-sized providers typically require more features to grow the company:
- more analytics capabilities;
- the ability to combine different types of user authorization;
- the ability to change technologies, for example, when switching from ADSL to OLT;
- development of new services, e.g. moving from multicast TV to OTT.
