Building the open alternative.

IP Infusion was founded in 1999. Its ZebOS routing stack, first shipped to telecom OEMs that year, has since been embedded in products from 300+ OEMs and is the control plane inside OcNOS today.

Today, OcNOS is in production with 900+ operators across 60+ countries, including service providers, internet exchanges, broadband providers and data center operators. It is qualified per model and ASIC stepping on open hardware from Edgecore, UfiSpace and Celestica, with an industry-standard CLI and NETCONF, gNMI and OpenConfig interfaces.

Pre-integrated OcNOS Systems ship with optics, support and RMA from one vendor. For software-only deployments, IP Infusion is accountable for the software.

What we believe about networking

Openness over lock-in

You should own your infrastructure. Open hardware, open standards and open APIs keep the choice of hardware with you.

Carrier-grade quality

Open doesn't mean experimental. OcNOS is hardened for production networks with high-availability requirements.

Engineer-first support

Our support engineers know the software and the hardware it is qualified on. With pre-integrated OcNOS Systems, one support contract covers both.

Global at scale

In production in 60+ countries, with offices in the US, Canada, Japan, South Korea, India and Germany.

A predictable release cycle

OcNOS has a five-year release life cycle, a GA release about every nine months, and maintenance releases typically 60 to 90 days after GA.

Ecosystem thinking

OcNOS is qualified on open hardware from Edgecore, UfiSpace and Celestica, and we work with distribution and technology partners such as EPS Global.
