Why operators choose GridM

  • Everything is managed from one central web console, no CLI or YANG to learn
  • Analytics, live per-subscriber graphs, DDoS and compliance are built in, with no external time-series database or dashboards to run
  • IPDR search, a legal-request workflow and an LEA role for lawful compliance, included
  • One plan with every feature, priced per subscriber

Where 6WIND shines

6WIND brings a very broad carrier routing feature set (IP/MPLS VPN, Segment Routing, EVPN, VXLAN) alongside vBNG and vCGNAT, deploys on bare metal, VMs or cloud-native, and has strong telco pedigree and ecosystem partnerships.

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

6WIND is a strong choice when the BNG is one function on a router platform that must also carry MPLS, Segment Routing or EVPN, and your team already operates CLI and YANG driven network functions with an external observability stack. GridM BNG is purpose-built for the subscriber edge and ships the whole operating model in the box: console, clustering, DDoS, analytics and compliance, on a simple per-subscriber plan.

Switching from 6WIND vBNG: 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 6WIND vBNG for at the broadband edge. Routing and other roles 6WIND platforms may also serve are evaluated separately in your design.
