Proven in production

OcNOS-SP runs in production networks worldwide, from the cell site to the IP core.

It runs on a routing stack with 26 years of development and ZebOS heritage, deployed on open hardware from Edgecore and UfiSpace across mobile, metro, broadband, and IP-core networks.

Where it fits in your network

One network from the cell site to the internet edge.

OcNOS-SP runs five service-provider use cases on one network, from the cell site to the internet edge. Every node runs the same OcNOS-SP image.

Cell-site gateway (CSR)

Cell site and RAN edge

OcNOS-SP terminates 4G and 5G xHaul at the cell site with IEEE 1588v2 and SyncE timing, backhauled over SR-MPLS on temperature-hardened platforms.

Why open

Open hardware, backed by one vendor.

You choose and refresh the hardware and the software separately, and IP Infusion supports the whole solution under one contract.

Approvisionnement matériel

Hardware from multiple vendors

Validated on Edgecore and UfiSpace platforms, from the compact cell-site router to the 14.4 Tbps core, so you source boxes from multiple vendors and keep procurement and pricing leverage.

Licensing economics

Price and refresh the box and the NOS separately

A single license per platform covers the ports and features, and you buy and refresh the hardware and the software on independent cycles.

Merchant silicon

Standard Broadcom merchant silicon

OcNOS-SP runs on standard Broadcom merchant silicon, the same class the incumbents put in the core, with a standards-based control plane of SR-MPLS, EVPN, and BGP that stays portable across platforms.

Accountability

Open hardware, single-vendor accountability

IP Infusion lab-validates the software and the open hardware together and backs both under one support contract, one escalation path, and one RMA, so you get open economics with a single vendor owning the integration.

See the open platforms OcNOS-SP is validated on in the hardware compatibility list.

Carrier-grade

Carrier-grade capabilities, each in the feature matrix.

The protocol depth and resiliency you would pay a proprietary core for are present here, each named to a standard and verifiable in the feature matrix.

Transport and fast reroute

SR-MPLS with Flex-Algo, SRv6 alongside

SR-MPLS per RFC 8402 with Flexible Algorithm per RFC 9350 and TI-LFA sub-50ms fast reroute, with SRv6 supported alongside SR-MPLS for L3VPN, EVPN, and traffic engineering, so you run the data plane your transport strategy calls for.

Full-table peering

A full internet BGP table with routing security

A full internet BGP table for transit and settlement-free peering, with RPKI origin validation and prefix filtering aligned with MANRS, route reflectors for scale, and BGP-LS and BMP for visibility.

5G timing and resilience

1588v2 and SyncE timing, backbone resiliency

IEEE 1588v2 with G.8275.1 full timing and G.8275.2 partial timing plus SyncE per G.8262 at the cell site, and BGP, OSPF, and IS-IS graceful restart, BFD, and VRRP and MLAG multihoming across the core, with redundant power and fans.

Before you trial

Questions SP architects ask.

OcNOS-SP is a purpose-built service-provider stack with a 26-year routing heritage, and it carries production traffic in more than 600 operator networks across 60+ countries. Each carrier-grade capability is named to a standard and verifiable in the feature matrix: SR-MPLS with Flex-Algo and TI-LFA sub-50ms fast reroute, a full internet BGP table with RPKI, MEF 3.0 Carrier Ethernet, and IEEE 1588v2 timing. OcNOS-DC is the separate data-center variant; the SP variant runs the P router, provider edge, aggregation, core, and cell-site roles.
Yes, at the capability level. OcNOS-SP runs the SR-MPLS core, full internet BGP table peering, MEF Carrier Ethernet, and 5G timing that a proprietary edge or core delivers, so you match capabilities role by role. Dojo Networks replaced Cisco transport routers with OcNOS on open hardware, and operators like Lintasarta and Telcom ran OcNOS interoperably with their installed Cisco, Juniper, and Nokia gear during a phased migration. The commercial model gives you open merchant-silicon hardware from multiple validated vendors, single-license economics, and one vendor accountable for the software, the boxes, and support.
SRv6 is supported alongside SR-MPLS, so operators run the data plane that matches their transport strategy. The SRv6 feature set includes L3VPN over SRv6, EVPN E-LINE and E-LAN for SRv6, PCEP for SRv6, SRv6 OAM, and IS-IS and OSPF SRv6 data-plane extensions on validated hardware. Contact us to confirm exact feature availability for your platform and release.
The cell-site gateway role delivers IEEE 1588v2 PTP with G.8275.1 full timing and G.8275.2 partial timing profiles, plus SyncE per G.8262 with ESMC quality-level signaling, on temperature-hardened cell-site platforms. This is the precision timing 4G and 5G xHaul requires, delivered from the same OcNOS-SP image that runs the transport core.
Yes. The IP core and peering role carries a full internet BGP table for transit and settlement-free peering, with RPKI origin validation and prefix filtering aligned with MANRS practices, route reflectors for scale, BGP-LS and BMP for visibility, and BGP FlowSpec to steer or drop attack traffic. The core platform, the UfiSpace S9610-36D on a Broadcom Jericho2C+ (BCM88850), provides 14.4 Tbps of switching capacity with deep buffering, the same class of merchant silicon the incumbents put in the core.
Resilience on a merchant-silicon router comes from the protocol layer and the hardware together: BGP, OSPF, and IS-IS graceful restart, sub-50ms TI-LFA and RSVP-TE fast reroute, BFD across single-hop, multi-hop, and SR paths, and VRRP and MLAG multihoming, with redundant hot-swappable power and fans. This is the resiliency model fixed open platforms deliver; OcNOS-SP does not claim redundant supervisors, stateful switchover, or in-service software upgrade.
No. OcNOS-SP is the aggregation and transport layer for broadband: it aggregates FTTx and OLT uplinks and fixed-wireless backhaul with hierarchical QoS and deep-buffer merchant silicon for microbursts, upstream of the access node. Subscriber termination, PPPoE, and subscriber AAA are out of scope for OcNOS-SP; a partner virtual BNG handles session termination where it is needed.
Migration is phased and interoperable, so you convert one role at a time. OcNOS-SP runs SR-MPLS and SRv6 alongside legacy LDP and RSVP, and interoperates with installed Cisco, Juniper, and Nokia routers during the transition. Multiple operators, including Dojo, Lintasarta, and Telcom, deployed OcNOS this way while their incumbent gear stayed in service. Cisco IOS-XR to OcNOS CLI translation assistance is available to speed configuration conversion. Contact us to scope a role-by-role plan.
