The software BNG/LNS that runs Netavo’s own network (subscriber termination, integrated CGNAT and full routing on standard x86 servers) is now available commercially, benchmarked at 200 Gbps from a single commodity server.
FOR IMMEDIATE RELEASE
London, United Kingdom, Oct 9, 2026
Netavo today announced the commercial release of Netavo BNG, the carrier-grade Broadband Network Gateway (BNG) and L2TP Network Server (LNS) software it has been running in production on its own network. Built by network operators rather than adapted from a router platform, Netavo BNG terminates PPPoE, IPoE and L2TP subscribers with integrated carrier-grade NAT (CGNAT) and a full BGP / MPLS routing stack on standard x86 servers and in the company’s own benchmarking saturates 200 Gbps of subscriber traffic from a single commodity server.¹
Why now
Broadband operators face a squeeze from several directions at once. Cisco’s long-serving ASR1000 edge routers have reached end-of-life, with software maintenance on the fixed-configuration line ending in 2026 and no like-for-like successor named. Years of altnet and open-access fibre build-out have created hundreds of regional ISPs that need a subscriber edge but cannot justify legacy chassis-based platforms, and a consolidating market is sharpening the focus on cost. IPv4 scarcity is forcing carrier-grade NAT into every network. And Chinese-origin BNG platforms are being removed from Western networks on security grounds. The incumbent chassis BNGs carry the capital cost and multi-axis licensing complexity of a previous era; Netavo BNG is built for the economics operators have today.
One system, from the access hand-off to the core
Netavo BNG consolidates the subscriber edge onto a single server:
– Subscriber termination: PPPoE, IPoE and L2TP (LAC and LNS), dual-stack, one session per access circuit, up to 100,000 concurrent subscribers.
– Integrated CGNAT (NAT44): included in every licence, with endpoint-independent filtering and sequence-numbered RFC 5424 port-block logging. Translating a subscriber does not make them a second billable unit. Also runs as a standalone CGNAT appliance.
– A full provider-edge routing stack: BGP with VPNv4/VPNv6, a selectable IGP (IS-IS or OSPF), MPLS L3VPN, per-service VRFs and ECMP.
– AAA to fit the operator: Flexible AAA driver support, including RADIUS or direct SQL database authentication; accounting to RADIUS or Azure Service Bus.
– Managed the way operators expect: a REST API (https://netavobng.com/docs/reference/api/), a browser-based web UI with two-factor authentication, and a familiar Junos-style CLI (https://netavobng.com/docs/reference/cli/) with configuration commit and rollback.
The data plane keeps forwarding while the control plane restarts or upgrades, a property Netavo relies on in its own network.
Under the hood, the data plane runs close to the metal. In DPDK mode it bypasses the kernel for maximum throughput on bare-metal servers; an AF_XDP mode runs the same forwarding software on virtually any NIC, including inside a virtual machine, for labs, smaller sites and virtualised deployments. The operator chooses the backend to match the hardware, and everything above it is identical.
Performance
In Netavo’s own benchmarking, the data plane sustains interface line rate at realistic internet traffic mixes (IMIX), not just at the large packet sizes vendors typically quote, with QoS and CGNAT enabled, scaling to 200 Gbps on a dual-100G server.¹ The figure is reproducible by any operator on the free evaluation build.
Quote
“We built this to run our own network, and we have been operating it in production over the past year, so we rely on it every day, exactly as our customers will,” said Chris Byrd, Netavo’s Chief Technology Officer. “Most BNG vendors have never had to operate their own product. We are releasing the exact software we run ourselves, licensed on one number (subscribers), with carrier NAT included, not sold back to you as an add-on.”
Licensed on one number
Netavo BNG is licensed on a single axis (concurrent subscribers), with every feature included in every band and no separate charges for CGNAT, routing or throughput. Put in a larger server and forward more traffic; the licence is unchanged. Band prices are quoted in GBP, EUR or USD.
Availability
A free evaluation build (the same binary Netavo runs in production, licensed for up to 50 concurrent subscribers with every feature enabled and no time limit) is available now at netavobng.com. Operators can deploy it on their own x86 hardware and benchmark it against their own traffic.
Optional production-support packages, from business-hours to 24×7 cover with response-time commitments, are available for operators running Netavo BNG live, priced as a sensible line item for a regional operator rather than an enterprise premium.
About Netavo
Netavo is a United Kingdom network operator and software company. Netavo BNG is built by network operators and carries production traffic on Netavo’s own network, terminating live wholesale L2TP, PPPoE and IPoE on the same software releases shipped to customers. More at netavobng.com.

¹ On the 200 Gbps figure. 200 Gbps is the aggregate line-rate capacity of a dual-100G server (two 100 GbE interfaces, full duplex). Netavo’s per-commit benchmark measures the data plane’s per-packet processing cost on x86-64; applied at IMIX packet sizes (around a 360-byte average frame) with QoS and CGNAT enabled, the measured cost leaves ample packet-rate headroom to fill both interfaces, so the interface, not the CPU, is the limit. The benchmark ships in the free evaluation build, so any operator can reproduce the measurement on their own hardware.
