GridM BNG vs Cisco BNG: the decision factors

Factor
GridM BNG
Cisco BNG
Architecture
Disaggregated software BNG on commodity x86
Integrated router chassis (ASR family) with BNG feature set
Hardware
Any OEM or white-box server, merchant NICs
Proprietary chassis, line cards and optics
Scaling model
Horizontal scale-out, add nodes with ECMP
Scale up within chassis limits, then add or replace chassis
Licensing
One plan, all features; ₹15/sub in India or per-node globally
Platform plus feature and scale licensing, subscriber tiers common
Deployment options
Bare metal, VM, containers or Kubernetes
Physical appliance; virtual options for parts of the portfolio
Upgrades
In-service software upgrades, canary per node
Software upgrades typically planned around maintenance windows
Management & APIs
One central web console, cluster-wide, plus a REST API for billing
Mature CLI, NETCONF/YANG and vendor tooling
Observability
Real-time per-subscriber analytics, built into the console
SNMP/telemetry via vendor tooling; per-subscriber depth varies
CGNAT and IPv6
Integrated CGNAT + native dual-stack IPv6, included
CGNAT often a separate card, appliance or license
Cost model
Pay as you grow on commodity hardware
High capex plus recurring licenses and support contracts

Why operators choose GridM

  • Runs on commodity x86 you can source from any OEM, no proprietary line cards
  • Capacity grows node by node instead of chassis by chassis
  • Transparent per-subscriber pricing instead of platform, feature and scale licenses
  • CGNAT, IPv6, DDoS visibility and per-subscriber analytics are built in

Where Cisco shines

Cisco BNG platforms are mature, feature-deep and backed by a global support organization and a vast installed base. For operators standardized on Cisco end to end, the ecosystem integration is a real advantage.

We believe in honest comparisons. Pick what fits your network; when the criteria are cost per subscriber, automation and freedom from lock-in, we are confident in GridM.

The verdict

If you are invested in a single-vendor Cisco estate and its ecosystem, a chassis BNG remains a safe, proven choice. If your next BNG decision is about cost per subscriber, automation and freedom to scale on your own hardware, GridM BNG delivers the same subscriber-management role as software, at commodity economics.

FAQ

Switching from Cisco BNG: your questions

For the BNG/BRAS role, yes. GridM BNG terminates PPPoE and IPoE subscribers, enforces per-plan QoS, speaks RADIUS with CoA and provides CGNAT and dual-stack IPv6, the functions operators deploy Cisco BNG for at the broadband edge. Routing and other roles Cisco platforms may also serve are evaluated separately in your design.
