Software BNG · vBNG · LNS · CGNAT · x86-64

Carrier-grade software BNG, LNS & CGNAT.

A software BNG — a virtual BNG (vBNG) — that terminates up to 100,000 subscribers (PPPoE, IPoE and L2TP LNS), with integrated CGNAT and a full BGP / IGP / MPLS L3VPN routing stack, on standard x86 servers.

One appliance, from the access hand-off to the core

Subscriber termination, carrier NAT and provider-edge routing on the same system — no separate boxes, no per-feature licences.

Subscriber termination

L2TP LNS for wholesale hand-offs, PPPoE access concentration, and IPoE with DHCP. A dual-stack subscriber is one session per access circuit.

RFC 2516 · RFC 2661 · TR-101 · Option 82

Explore termination

Routing on the box

BGP with VPNv4 and VPNv6, a selectable IGP (IS-IS, OSPF, or none), MPLS L3VPN and per-service VRFs. The BNG is a first-class provider edge in your core.

Carrier-grade NAT (CGNAT), included

NAT44 with sequence-numbered port-block logging, in every licence. Translating a subscriber does not make them a second billable unit.
