Replace expensive hardware BNG with Kynex vBNG — a software-defined Broadband Network Gateway delivering carrier-grade session management on standard x86 servers.
Full support for PPPoE and IPoE (DHCP-based) subscriber session termination on commodity x86 hardware — no proprietary ASICs required.
DPDK-accelerated packet forwarding delivering multi-hundred-Gbps throughput per node with line-rate QoS enforcement.
Granular upload and download policing per subscriber session based on RADIUS-delivered speed attributes. Dynamic rate changes via CoA with zero session drop.
Stateful session replication between primary and standby nodes. Sub-second failover with no subscriber reconnection required.
Integrated DHCP server with RADIUS-driven IP pool assignment, static IP binding, and CGNAT for IPv4 address conservation.
Application-aware traffic classification for analytics, QoS prioritization (VoIP, gaming, streaming), and fair-use policy enforcement.
Native MPLS PE functionality for seamless Layer 3 VPN handoff to enterprise customers and MPLS backbone connectivity.
Real-time and historical session dashboards showing subscriber counts, throughput, protocol distribution, and top talkers.
End-user device initiates PPPoE or DHCP session to the access switch/OLT which forwards to vBNG.
vBNG creates a session context and sends RADIUS Access-Request to ISP CRM AAA server.
ISP CRM validates credentials, returns Access-Accept with speed attributes (upload/download limits, IP pool).
vBNG applies QoS policies, assigns IP address, begins RADIUS Accounting. Subscriber is online.
RADIUS Interim-Update accounting packets sent every 5 minutes. CoA messages allow real-time speed or plan changes.
