SOLUTIONS FOR BROADBAND PROVIDERS

BNGSOFT broadband providers are driving the deployment of higher internet speeds and the adoption of broadband services in rural communities. Rural providers deliver essential, high-speed broadband services to residents and virtually all major institutions in their communities, including schools, hospitals, and public libraries. In addition, they are rapidly replacing old copper networks with fiber. BNGSOFT is built to help rural providers easily and economically build high-speed networks, whether it’s a fiber buildout or increasing network scalability with minimal infrastructure investments.

Automate Subscriber Provisioning and Management

• Broadband Access Service routers and Broadband Network Gateway routers (BRAS or BNG) are the critical routing infrastructure carriers and service providers use to enable network and subscriber management automation. Using a BNG in the network eliminates manual subscriber provisioning, adding automation and integration into Service Provider billing and other operational systems.
• BNGSOFT includes DHCP, PPPoE services, and IP Address management while interfacing with your billing system via RADIUS to authenticate subscribers, set their appropriate rate and services profile, and provide the accounting records back to RADIUS for your billing system.
• This automation reduces theft of service, service and rate plan inconsistencies, and manual provisioning errors that can lead to poor customer experience.

Software Flexibility

• BNG is a full featured broadband access services router (sometimes called a BRAS) that runs on x86 commercial off-the-shelf (COTS) hardware. This approach allows network operators to select the scale and deployment design that best fits their network, whether it’s a large centralized platform or a set of smaller decentralized BNGs deployed close to the customer edge. And since it runs on standard COTS hardware and works with all OLT and DSLAM equipment, there is no hardware vendor lock-in.

Performance and Scalability

• One 1RU server forwards 50 Mpps with PPPoE, CGNAT, hierarchical QoS and ACLs all enabled — about 110 Gbit/s at 256-byte frames, or 33.6 Gbit/s at 64-byte worst case. Packet rate is the limit, so the bandwidth you get depends on your average frame size. Port capacity reaches 400 Gbit/s with two dual-port E810 cards. For smaller sites the same software starts at 2 × 10 Gbit/s and scales up as demand (and revenue) grows.

Build-in CGNAT 

• Service providers in many countries can’t get sufficient IPv4 address space and are forced to add expensive extra CGNAT cards or appliances. BNGSOFT BNG includes built-in CGNAT with no additional licensing fees.BNGSOFT CGNAT supports detailed session logging, which is compatible with many government regulations.

The Advanced Features You Need

•  BNGSOFT provides all of the features required to operate the network and manage subscriber access without paying for unnecessary features. IPoE/DHCP and PPPoE services, ACL, QoS, rate profiles, and IP address management are all included. RADIUS AAA (with COA) allows integration with billing and automation, and BGP, OSPF, and ISIS routing protocols support core network requirements. MPLS features, including subscriber to VRF mapping, support business broadband for enterprise clients.

PPPoE subscriber session

• The PPP-over-Ethernet (PPPoE) subscriber session is established using the point-to-point (PPP) protocol that runs between the customer-premises equipment (CPE) and the broadband network gateway (BNG). It is designed for managing how data is transmitted over Ethernet, and it allows a single server connection to be divided between multiple clients.

IPoE subscriber session

• The IP-over-Ethernet (IPoE) subscriber session is established using the IP connection that runs between the CPE and the BNG; IP addressing is done using the DHCP protocol. IPoE is essentially DHCP triggered subscriber interfaces. Users are “authenticated” through the combination of incoming interface and MAC address. This identifies the physical location of the user based on the queue they are connected to.
• To control subscribers’ sessions and to collect statistics, AAA (authentication, authorization and accounting) is necessary. With RADIUS integration, all information will always be in synchronization with your billing database, which allows providing refined operational services with identity authentication of broadband users, package and service authorization, and calculation of charges.
