Built for engineers who refused to accept lock-in.
IP Infusion pioneered software-defined, disaggregated networking long before it was a trend. We deliver carrier-grade NOS on open, validated hardware, so you control your network, your cost, and your future.
26 years of building the open alternative.
In 1999, IP Infusion was founded with a radical idea: networking software should be separated from the hardware it runs on. We built ZebOS, one of the first commercially successful software-only routing platforms, and never looked back.
Today, OcNOS runs in 600+ operator networks across service providers, telcos, internet exchanges, broadband providers, and enterprise data centers. We combine open-source foundations (FRR, SONiC, OpenConfig) with carrier-grade hardening, a unified support contract, and hardware validation that saves months of integration work.
We don't compete with our customers. We enable them, and we've been doing it for over two decades.

What we believe about networking
Openness over lock-in
You should own your infrastructure. Open hardware, open standards, open APIs: no vendor dependency, no proprietary trap.
Carrier-grade quality
Open doesn't mean experimental. OcNOS is hardened for 24/7 production with five-nines availability requirements.
Engineer-first support
Our support engineers understand the hardware and the software. One call, one team, one answer, not a ticket queue.
Global at scale
Deployed in 60+ countries with local teams in the US, Japan, South Korea, India, and Germany.
Continuous innovation
From 10GE aggregation to 400G AI fabric, OcNOS evolves with every generation of networking technology.
Ecosystem thinking
We partner deeply with Edgecore, UfiSpace, EPS Global, and Fujitsu, because no one company builds everything best.
