OcNOS — the brain inside the box.
Hardware is the body. OcNOS is the brain. It's the carrier-grade software that turns an open switch into a real router — service-provider, data-center, AI-fabric, OEM. One NOS. Every motion. Already in 600+ live networks.
A switch without a NOS is just an expensive doorstop.
A network operating system is the software that decides what every packet does, talks BGP to the rest of the internet, programs the merchant-silicon ASIC, exposes APIs for automation, and stays up at 3 a.m. on a holiday weekend.
It's hardware that doesn't know it's a router.
An open switch from Edgecore or UfiSpace ships as a Broadcom ASIC inside a steel chassis. Powerful — but mute. No BGP. No EVPN. No CLI. No telemetry. No way to push config. No way to fail over a link in 50 ms. It's a $25,000 paperweight until something tells it what to do.
The same box becomes a carrier-grade router.
Boot OcNOS and the chassis becomes a real piece of network infrastructure. BGP holds 2M+ internet routes. SR-MPLS computes Flex-Algo paths. EVPN-VXLAN stitches a leaf-spine fabric together. RoCEv2 stops dropping packets in your AI cluster. The same CLI engineers already know. The same APIs orchestrators already speak. The same SLA across hardware, software, and RMA.
Click any layer to see what's actually in there.
Open hardware at the bottom. ZebOS routing daemons in the middle. NETCONF and gNMI on top. Six layers. Hover or click — they tell you what they do.
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.
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.
The ZebOS stack — 26 years of routing in production.
Multi-protocol routing daemons: BGP, OSPF, IS-IS, PIM, BFD, LDP, RSVP-TE, SR-MPLS, SRv6, EVPN-VXLAN, the full DCB stack for lossless RoCEv2, IEEE 1588v2 timing, MEF 3.0 Carrier Ethernet, OpenZR+ coherent optics. One codebase, every motion.
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.
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.
50+ qualified platforms. Buy the box that fits the build.
Compact 5G cell-site gateways through 14.4 Tbps SP core routers and 51.2 Tbps 800G AI-fabric spines. From Edgecore, UfiSpace, EPS Global, and partner ODMs. All on Broadcom merchant silicon. Same OcNOS image runs across the catalog.
Three production motions. One NOS. Pick a tab.
Service-provider routing, data-center fabric, and AI fabric — full-strength feature sets, not "primary use case + side projects." Plus OEM, where the same routing stack ships embedded inside vendor products.
Carrier-grade SR-MPLS, IPoDWDM, and 5G xHaul on open hardware.
The same feature set Cisco IOS-XR, Juniper Junos, and Nokia SR OS deliver — running on Broadcom merchant silicon at materially lower TCO. Already in production at NTT, Multinet, eww ITandTEL, and 600+ networks worldwide.
- SR-MPLS, SRv6, Flex-Algo, TI-LFA <50ms FRR
- MEF 3.0 Carrier Ethernet, hQoS, Y.1731 OAM
- 400G OpenZR+ IPoDWDM, no transponder shelves
- IEEE 1588v2 G.8275.1/.2 + SyncE for 5G xHaul
EVPN-VXLAN leaf-spine on Broadcom Tomahawk and Trident.
Drop-in alternative to Arista EOS and Cisco Nexus NX-OS. eBGP unnumbered underlay, EVPN overlays, ZTP rack onboarding, gNMI streaming telemetry. The DC fabric is the same OcNOS image as the SP edge — same engineers, same playbook.
- EVPN-VXLAN overlays with multi-homing & ARP suppression
- ZTP zero-touch provisioning over IPv4 & IPv6
- gNMI streaming telemetry into Prometheus / OpenTelemetry
- DCI gateway: VXLAN extended over 400G ZR+ to remote DC
800G GPU networking that doesn't drop a single packet.
The complete DCB stack — PFC, ECN, ETS, DLB — pre-tuned for RoCEv2 RDMA on Broadcom Tomahawk 5 800G spines (Edgecore AIS800-64D, UfiSpace S9321-64E) with Tomahawk 4 400G leaves. Equivalent performance to NVIDIA Spectrum-X. Open hardware. Carrier-grade SLA. The CapEx you save buys more GPUs.
- PFC + ECN + ETS — true lossless queues for RDMA
- Dynamic Load Balancing kills AllReduce hotspots
- eBGP unnumbered underlay, ZTP, DCBX automation
- Per-priority pause counters & ECN marks via gNMI
Ship hardware? Put 26 years of routing inside it.
Hardware vendors don't have to write a routing stack from scratch. License OcNOS Flex (binary NOS for fast deployment) or OcNOS CP (source-code control plane for deep integration with custom data planes). Already inside 300+ vendor products today.
- Flex: turnkey binary NOS, fastest to market
- CP: source-code control plane, custom data plane
- ZebOS lineage — embedded since 1999
- Per-device or per-unit royalty models — talk to sales

Tier-1 carriers. National backbones. AI clusters.
600+ operator networks across 60+ countries running OcNOS in production — Tier-1 IOWN transport, sovereign MPLS, regional broadband, 5G xHaul, data-center fabric, AI clusters. Same NOS, every motion.
Why pick OcNOS over Cisco, Juniper, Arista, Nokia?
Same carrier-grade feature set. Open Broadcom hardware. Single accountable vendor for software, hardware, and RMA. And no DIY-SONiC integration tax.
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 →
