The broadband gateway, rebuilt as software
GridM BNG terminates PPPoE and IPoE subscribers at line rate on commodity x86, speaks RADIUS to the billing you already run, and scales out node by node. No chassis, no forklift upgrades, no lock-in.

Terminating subscribers for operators like
Legacy BNG chassis are where budgets go to die
The box that terminates your subscribers was designed for a world without cloud, APIs or commodity 100G. Operators pay for that history every year.
Forklift upgrades
Chassis hit end-of-life or a capacity ceiling, and the only path forward is another seven-figure box with months of lead time.
Licensing that fights you
Feature unlocks, scale licenses and support renewals are bound to the chassis and renegotiated on the vendor's terms, not yours.
Closed, CLI-only boxes
No real APIs, no central console, no automation. Every change is a maintenance window and every integration is a professional-services quote.
Scaling by chassis, not by need
Capacity comes in giant, expensive steps. You overprovision for years or run hot with no headroom, and redundancy doubles the bill.
Everything the chassis did. Everything it never could.
One horizontally scalable software package: session termination, AAA, addressing, QoS, CGNAT, HA and observability.
Subscriber session termination
PPPoE and IPoE (DHCP) termination that scales to hundreds of thousands of sessions per node.
AAA and policy
Standards-based RADIUS that drops into the billing and CRM stack you already run.
Addressing, IPv6 and CGNAT
Stretch scarce IPv4 with integrated CGNAT while rolling out native dual-stack IPv6.
QoS and plan enforcement
Enforce every plan, fairly, at line rate, without external shaper boxes.
Line-rate data plane
A kernel-bypass forwarding plane that turns commodity NICs into carrier capacity.
High availability
Carrier availability from redundant software, not redundant chassis.
Sits exactly where the chassis sat. Behaves like a cloud.
GridM BNG terminates subscribers between your access network and IP core, exactly like the hardware it replaces. Your OLTs, your RADIUS, your upstreams: nothing else changes.
- Interoperates with any OLT, DSLAM, switch or wireless access layer
- Same RADIUS and billing stack, with CoA for live plan changes
- N+1 cluster with session sync: node loss is a non-event for subscribers
- Scale from one 1U server to a terabit POP with ECMP scale-out
Run your whole network from one beautiful screen
There is no CLI to learn and no boxes to log into one by one. Every session, pool, plan, CGNAT setting and security policy is managed from a single web console that spans the whole cluster in real time. Preview a change, apply it everywhere, and read the audit trail after.
- Central, cluster-wide control
- Preview then apply, everywhere
- Role-based access + audit log
- Everything built in, nothing to bolt on

Figures from a single production GridM BNG cluster (two nodes, N+1) at an FTTH ISP in Delhi.
“We moved our subscriber termination from hardware to GridM BNG and stopped thinking about the BNG as a constraint. Sessions, CGNAT, IPv6 and per-subscriber visibility run on servers we already know how to buy and fix, and the console shows us in seconds what used to take a CLI session and a prayer.”

Questions network engineers ask first
Straight answers on architecture, migration, licensing and interop.
A software BNG (also called a virtual BNG or vBNG) implements the Broadband Network Gateway function, subscriber session termination, AAA, addressing and QoS, as software on standard x86 servers instead of a proprietary hardware chassis. GridM BNG is a cloud-native software BNG: it terminates PPPoE and IPoE sessions at line rate on commodity NICs and runs on bare metal, VMs or Kubernetes.
