Your own BNG and CGNAT platform

An operator that terminates its own subscribers needs a broadband network gateway. Netavo BNG is ours: carrier-grade software for standard x86 servers, with CGNAT and a full provider-edge routing stack included.

One platform

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

Function	What is included
Subscriber termination	PPPoE, IPoE and L2TP LNS, with a dual-stack subscriber held as one session per access circuit
Routing	BGP, IS-IS or OSPF, and MPLS L3VPN with per-service VRFs
CGNAT	NAT44 with port-block logging, included in every licence
AAA	RADIUS with change of authorisation and disconnect, or a direct database driver
Management	A management portal showing live subscriber sessions across every access type

Live subscriber sessions in the Netavo BNG management portal — The management portal on demonstration data, showing live subscriber sessions across PPPoE, IPoE and L2TP LNS.

Software, on servers you choose

Netavo BNG runs on standard x86-64 servers. There is no proprietary appliance, so capacity is an engineering decision and not a commercial one.

It is licensed by subscriber count only, with no bandwidth tiers, per-core charges or feature add-ons, and its pricing is published.

Why it suits each kind of operator

Operator	What Netavo BNG gives them
Altnets and fibre builders	IPoE and PPPoE termination for their own access network, as a provider edge in their core
Regional and independent ISPs	An L2TP LNS for wholesale broadband handed over from the access networks
Wireless ISPs	Subscriber termination with CGNAT included, where public IPv4 addresses are scarce

Or let us run it

An ISP that would sooner not operate a BNG at all can have its subscribers terminated on ours. Managed subscriber termination uses Netavo's own BNG, on the same software releases.
