The network operating system market is undergoing a structural shift. Proprietary NOS vendors no longer have a monopoly on carrier-grade features. Open networking platforms have matured to the point where mission-critical service provider deployments — hundreds of nodes, millions of subscribers — run on open, disaggregated architectures. The question for most operators is no longer whether to adopt open networking, but which path to take.
This is Part 4 of the IP Infusion NOS comparison series — the definitive summary.
The Four NOS Options in 2024
| Option | Ejemplos | Model | Best For |
|---|---|---|---|
| Proprietary | Cisco IOS-XR, Juniper Junos, Nokia SR OS | Closed HW+SW bundle | Operators wanting single-vendor simplicity with budget flexibility |
| SONiC comercial | Dell OS10, Arista EOS-based, Cisco SONiC | Open HW, SONiC-derived SW | Pure DC leaf/spine, Broadcom-only, large engineering teams |
| SONiC comunitario | Azure SONiC, SONiC-VS | Open source, DIY | Hyperscalers with dedicated NOS engineering teams |
| OcNOS (IP Infusion) | OcNOS-SP, OcNOS-DC | Open HW, commercial SW | SP + DC, full protocol stack, production support required |

Decision Framework
Bottom Line
There is no universally correct NOS answer. The right choice depends on your use case, team capabilities, and risk tolerance. What has changed is that the argument for staying with proprietary NOS — that open alternatives lack the features and support quality required for production — is no longer accurate. OcNOS has 600+ customers, 10,000+ production deployments, TL 9000 certification, and MEF 3.0 compliance to substantiate that claim.
