Broadband network gateway software for controlled subscriber access
Turn subscriber policy into network action.
X-BNG connects subscriber sessions, AAA policy, address assignment and service control at the broadband edge. Combined with XIMS, commercial events and network enforcement operate from one accountable workflow.
The subscriber edge between access and service delivery
X-BNG is designed to establish and control broadband subscriber sessions while keeping policy decisions synchronized with XIMS. It gives network teams visibility into who is connected, how the session was authorized, which service policy applies and what operational action was performed.
Support the access model your network uses
One policy chain from plan to session
- XIMS subscriber and billing state — the commercial source of truth for what the session is entitled to.
- RADIUS authorization — authentication, authorization and service attributes issued against that state.
- X-BNG session enforcement — the session carries the authorized policy at the network edge.
- Accounting and operational feedback — usage and session events flow back for billing, FUP and investigation.
Change-of-Authorization, disconnect, speed-profile changes, expiry and reconnection, and FUP policy operate along this chain. See the dedicated RADIUS billing software page for AAA detail.
Govern addressing and traffic at the subscriber edge
- IPv4 address and pool assignment
- IPv6 readiness and prefix workflows where verified
- VLAN/QinQ subscriber context
- Upload/download policies
- QoS and service profiles
- CGNAT integration and logging boundaries
- Route and service-policy controls
Deploy for the scale and failure model you actually have
Deployment modes, redundant nodes, session-state considerations, upstream and downstream integration, observability, maintenance windows and capacity planning are designed around each network’s architecture. Rather than publishing unsupported throughput figures, Xonware provides a sizing exercise against your subscriber count, session profile and traffic model — request a sizing discussion.
Network operations without command-line guesswork
Operations teams work through governed screens: session search, subscriber context, node health, address pools, policy application, task history and controlled service operations. Every GUI action exposes its validation, authorization and audit status.
Billing, subscriber state and network enforcement stay aligned
Verified payment can drive automated service activation. Policy conditions can drive suspension. Plan changes can drive speed changes. Support teams can investigate a live session directly from Subscriber 360. Every commercial and network action lands in one audit history.
Frequently asked questions
What is a Broadband Network Gateway?
A BNG is the network function that establishes, authorizes and controls broadband subscriber sessions at the edge between the access network and service delivery, applying policy such as speed, addressing and access state.
Does X-BNG support PPPoE and IPoE?
X-BNG supports PPPoE session workflows through RADIUS, and verified DHCP-based IPoE subscriber-identification workflows appropriate to the deployment design.
How does X-BNG integrate with RADIUS?
X-BNG consumes RADIUS authentication, authorization and accounting, including Change-of-Authorization and disconnect workflows, so session policy follows subscriber state.
Can X-BNG work with XIMS billing and subscriber management?
Yes. XIMS subscriber and billing state drives RADIUS policy, and X-BNG enforces it at the session, with accounting and audit context flowing back.
Is X-BNG available for high-availability deployment?
X-BNG is designed for redundant-node deployment; the specific high-availability architecture is scoped with your team during a sizing and design discussion.
