OcNOS-SP
Service Provider NOS
Carrier-grade network operating system for SR-MPLS, 400G IPoDWDM, and 5G xHaul. Reduce TCO by up to 60% using validated Edgecore and UfiSpace open hardware.
Built for the operators running carrier networks.
From Tier-1 core routing to rural broadband to 5G cell-site gateways — one NOS, four SKU tiers, validated open hardware.
SR-MPLS, full internet table — on open silicon.
"Cisco IOS-XR and Juniper Junos deliver the feature set — at a cost structure that breaks modernization budgets."
SR-MPLS with Flex-Algo (RFC 9350), TI-LFA sub-50 ms FRR, 2M+ BGP routes, EVPN VPWS/E-LINE, MEF 3.0 Carrier Ethernet. Deployed at Tier-1 scale in production.
SP-MPLS · SP-PLUSScale subscribers without waiting on vendor integration.
"BEAD and competitive broadband run on fixed timelines — proprietary vendor lead times don't fit."
IP-BASE routing, EVPN-VXLAN, ZTP Day-0 provisioning. Access, aggregation, and metro from one NOS on Edgecore and UfiSpace — deployable in weeks, not quarters.
SP-IP-BASE · SP-MPLSTIP DCSG cell-site gateways with Class C/D timing.
"5G fronthaul needs sub-100 ns phase accuracy. 4G backhaul still does. One hardware line-up would be nice."
IEEE 1588v2 G.8275.1/G.8275.2, SyncE G.811, MPLS-TP. TIP DCSG Gold Badge. Compact platforms (UfiSpace S9501-28SMT) sized for fronthaul, midhaul, backhaul.
CSR · TIP DCSGCarrier-grade features. Open economics.
First Open NOS with Carrier Ethernet Certification
The only open network OS to hold MEF 3.0 certification — the same standard required by carrier SLAs for E-Line, E-LAN, E-Tree, and E-Access services. Y.1731 OAM, CFM, and hQoS included.
Sub-50ms TI-LFA Convergence
Topology-Independent Loop-Free Alternates pre-compute backup paths for all primary routes. Link or node failure triggers protection in under 50ms without waiting for IGP reconvergence.
400G ZR/ZR+ in a Single Chassis
OpenZR+ coherent optics in QSFP-DD eliminates dedicated transponder shelves. DCI and metro spans up to 1000km on the same platform running IP routing.
IEEE 1588v2 & SyncE for xHaul
G.8275.1 full on-path timing and G.8275.2 partial timing profiles. SyncE frequency synchronization. Meets 3GPP and O-RAN timing requirements for fronthaul and midhaul.
2M+ Routes — Full Internet Table
Peer with every Tier-1 transit provider simultaneously. RPKI origin validation, BGP-LS topology export to controllers, BMP for route monitoring. Tested at production Tier-1 scale.
Single Support Contract — Software + Hardware + RMA
One SLA across OcNOS-SP, the validated Edgecore or UfiSpace platform, and RMA logistics. No multi-vendor finger-pointing when a Tier-1 core router takes a hit at 3 a.m.
OcNOS-SP Deployment Topology
From internet peering through SR-MPLS core to 5G backhaul and IPoDWDM metro — one NOS, one vendor, one support contract.

OcNOS-SP vs. Cisco IOS-XR / Juniper Junos / Nokia SR OS
Same carrier-grade feature set. Open hardware. Materially lower CapEx and OpEx — with a single accountable vendor.
Also an alternative to DIY SONiC and white-box assembly. OcNOS-SP is a commercial carrier-grade NOS with 24/7 TAC, single-vendor SLA, and RMA logistics. SONiC, DANOS, VyOS, and FRR require internal integration, validation, and third-party support — engineering overhead IP Infusion absorbs.
Shipping in carrier networks since 1999.
600+ operator networks across 60+ countries run OcNOS-SP in production — from Tier-1 IOWN transport to sovereign MPLS backbones to rural broadband and 5G cell-site gateways.
Multinet
Country-wide open optical and packet transport IP network — one of the largest disaggregated backbones in production on OcNOS.
NTT
400G IOWN network solution with NTT — carrier-class coherent transport running on OcNOS-SP.
eww ITandTEL
Sovereign MPLS backbone modernization on 400G ZR+ coherent optics — full IPoDWDM integration from the routing CLI.
