What a NOS does

Open hardware becomes a router or switch only when a NOS runs on it.

A network operating system forwards every packet, runs BGP with the rest of the internet, programs the merchant-silicon ASIC, exposes APIs for automation, and keeps the network up around the clock.

Without a NOS

Open hardware, before a NOS.

An open switch from Edgecore or UfiSpace ships as merchant-silicon hardware with no networking software on it: no BGP, no EVPN, no CLI, no telemetry, and no way to push config or fail over a link until a NOS is installed.

[ no os installed ]
With OcNOS

The same box becomes a carrier-grade router or switch.

Boot OcNOS and the same box becomes carrier-grade infrastructure. BGP holds the full internet table, SR-MPLS computes Flex-Algo paths, EVPN-VXLAN builds the leaf-spine fabric, and RoCEv2 keeps the AI cluster lossless. It runs the CLI engineers already know, the APIs orchestrators already speak, and one SLA across hardware, software, and RMA.

Inside the box

The OcNOS stack, layer by layer.

Open hardware at the bottom, ZebOS routing daemons in the middle, and NETCONF and gNMI on top. Six layers; select any one to see what it does.

Layer 06: Orchestration

IP Maestro runs your fleet without a fleet engineer.

Day-0 zero-touch provisioning, Day-1 golden-config templates, Day-2 drift detection, gNMI telemetry to your dashboards. Optional, but if you operate dozens or hundreds of OcNOS nodes you'll want it. Plays nicely with Ansible and Terraform too.

ZTPGolden config Drift detectTelemetry AnsibleTerraform
Layer 05: Northbound

Open APIs. Standard models. Nothing proprietary.

Industry-standard CLI for engineers who came from any major NOS. NETCONF/YANG, gNMI, OpenConfig, RESTCONF for automation. BGP-LS and BMP for controllers. Streaming telemetry into Prometheus, OpenTelemetry, your tool of choice.

Layer 03: HAL

One control plane, every Broadcom ASIC family.

The Hardware Abstraction Layer translates control-plane intent into ASIC programming on Tomahawk 4/5, Trident, Qumran2, and Jericho2. Operators don't need to care which silicon ships under the covers: OcNOS speaks all of them.

Layer 02: Boot & OS base

ONIE installs. ONL boots. Standard tooling everywhere.

Open Network Install Environment loads OcNOS the same way every other open NOS gets installed: drop an image, reboot, done. Underneath, the Open Network Linux base means engineers can use the Linux tools they already know.

The spec sheet

One OcNOS image, from the metro edge to the AI fabric.

The same OcNOS that runs carrier and transport networks in production also builds the AI Ethernet fabric on the same software. You do not trade carrier-grade routing to get a modern data-center fabric, and you do not run a data-center-only NOS that cannot carry your transport. Every capability below is the same binary in both columns: one image, one CLI, one support contract, one RMA path.

Same carrier-grade feature set, open Broadcom hardware, and one accountable vendor for software, hardware, and RMA, with no self-integrated SONiC build to maintain.

✕ Proprietary chassis (Cisco · Juniper · Arista · Nokia)
Proprietary ASICs and chassis: material hardware premium
Per-feature licensing: coherent optics, timing, advanced routing à la carte
Vendor-controlled refresh cycles & roadmap dependencies
Different products for SP, DC, and AI fabric: operational silos
✓ OcNOS on open Broadcom hardware
Broadcom merchant silicon on Edgecore / UfiSpace ODMs, at significantly lower CapEx
Full feature stack in the SKU: no per-feature license tax
Single IPI support contract covers software, hardware, and RMA
One NOS image across SP, DC, AI Fabric, OEM: one ops team

Also an alternative to DIY SONiC. SONiC, DANOS, FRR, and VyOS require internal integration, ASIC validation, and third-party support: engineering overhead IP Infusion absorbs. OcNOS ships with 24/7 TAC, single-vendor SLA, MEF 3.0 / TIP DCSG / EANTC certifications, and 26 years of routing-stack heritage. Detailed Juniper comparison →

FAQ

Frequently asked questions

OcNOS is IP Infusion's commercial network operating system: the software that turns an open switch from a box of silicon into a real router. It runs in 600+ operator networks across 60+ countries on 40+ validated open hardware platforms. One NOS covers service-provider routing (SR-MPLS, IPoDWDM, 5G xHaul), data-center fabric (EVPN-VXLAN, leaf-spine), AI fabric (lossless RoCEv2 on Broadcom Tomahawk 5), and OEM embedded networking. Its routing stack, ZebOS, has shipped in carrier and OEM products continuously since 1999.
OcNOS-SP is the service-provider edition: SR-MPLS, SRv6, BGP at full-internet-table scale, MEF 3.0 Carrier Ethernet, IEEE 1588v2 timing for 5G xHaul, and 400G IPoDWDM with OpenZR+ coherent optics. OcNOS-DC is the data-center edition: EVPN-VXLAN leaf-spine overlays, lossless RoCEv2 with PFC and ECN for AI/GPU clusters, ZTP, gNMI streaming telemetry on Broadcom Tomahawk and Trident silicon. OcNOS for OEMs ships in two licensing models, Flex (binary NOS for hardware vendors) and CP (source-code control plane for custom routing stacks), already in 300+ vendor products.
Yes, and that is the core of what OcNOS does. The same OcNOS image runs service-provider and transport networks (SR-MPLS, SRv6, IPoDWDM 400G coherent, MEF 3.0 Carrier Ethernet, IEEE 1588v2 timing) and data-center and AI Ethernet fabric (EVPN-VXLAN, lossless RoCEv2 with PFC over L3, ECN, DCQCN, and DLB on Broadcom Tomahawk 5). It is one binary, one CLI, and one support contract, so a neocloud or operator running both an AI training or inference fabric and a carrier WAN uses a single operations model and one team instead of learning two separate operating systems. OcNOS runs the carrier and transport side in production today across 600+ networks; the AI fabric is built on the same software on open 800G hardware. See the neocloud networking solution for the one-fabric build.
Yes, at production strength. OcNOS-DC ships a complete Data Center Bridging stack tuned for RoCEv2 RDMA: PFC for lossless queues, ECN for early backpressure, ETS for class scheduling, and DLB to prevent ECMP hotspots in AllReduce traffic. Validated on Broadcom Tomahawk 5 800G platforms (Edgecore AIS800-64D, UfiSpace S9321-64E) for spines and Tomahawk 4 400G for leaves. Production AI fabrics deploy with eBGP unnumbered underlay, ZTP, and gNMI telemetry into Prometheus or OpenTelemetry. See the AI Fabric solution page.
Versus proprietary NOSes (Cisco IOS-XR, Juniper Junos, Nokia SR OS, Arista EOS, Cisco Nexus NX-OS): OcNOS competes on feature parity but runs on open Broadcom hardware from Edgecore and UfiSpace at materially lower CapEx. Versus open-source SONiC, DANOS, VyOS, FRR: OcNOS is a commercial carrier-grade NOS with 24/7 TAC, single-vendor SLA covering software/hardware/RMA, and 26 years of routing-stack heritage. SONiC requires internal integration, ASIC validation, and third-party support: engineering overhead IP Infusion absorbs. Detailed Juniper comparison →
OcNOS runs on 40+ validated open hardware platforms based on Broadcom merchant silicon (Qumran2, Jericho2, Trident 4, Tomahawk 4 and 5), sourced from Edgecore, UfiSpace, EPS Global, and other ODM partners. Form factors range from compact 5G cell-site gateways through 14.4 Tbps SP core routers to 51.2 Tbps 800G AI-fabric spines. The full Hardware Compatibility List shows per-platform feature support.

Yes. OcNOS holds MEF 3.0 Carrier Ethernet certification (E-Line, E-LAN, E-Tree services), the TIP DCSG Gold Badge for 5G cell-site gateways, EANTC interoperability validation for IP transport, and IEEE 1588v2 G.8275.1/G.8275.2 timing-profile compliance. Deployed in the NTT 400G IOWN solution, at DIGI and Uniti Fiber, eww ITandTEL (sovereign MPLS Austria), Exatel (Poland), and across 60+ countries.
ZebOS is IP Infusion's multi-protocol routing stack, first shipped to telecom OEMs in 1999 and embedded in 300+ vendor products since. It implements BGP, OSPF, IS-IS, MPLS, segment routing, BFD, PIM: the full carrier-grade routing protocol set. OcNOS is the productized NOS that wraps ZebOS: the same control-plane code operators have trusted in OEM equipment for 26 years, packaged with the hardware abstraction layer, northbound APIs (NETCONF/gNMI/OpenConfig), and IP Maestro orchestration. OEMs can still license ZebOS as a control-plane source product via OcNOS CP.
An open network operating system (open NOS) is router and switch software that is decoupled from the hardware, so the NOS and the underlying switch can be sourced separately instead of bought as one fixed appliance. This gives operators hardware choice, multi-vendor sourcing, and open economics while keeping standard routing, EVPN, and automation. OcNOS is a production open NOS, delivered by IP Infusion as complete routers and switches.
OcNOS is a commercial open NOS, not open-source software. Open here means open hardware and open standards: OcNOS runs on standard merchant-silicon switches rather than locked appliances. Unlike community open-source projects, it ships as a supported product with 24/7 TAC and a single SLA across hardware, software, and RMA, and IP Infusion delivers it as complete routers and switches.
