Why OcNOS-SP

Carrier-grade features. Open economics.

MEF 3.0 Certified

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.

Fast Reroute

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.

Coherent Optics

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.

5G Timing

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.

Route Scale

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.

One Accountable Vendor

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.

Architecture

OcNOS-SP Deployment Topology

From internet peering through SR-MPLS core to 5G backhaul and IPoDWDM metro: one NOS, one vendor, one support contract.

How We Compare

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.

✕   Proprietary SP Routing (Cisco / Juniper / Nokia)
Proprietary ASICs: significant hardware premium vs open ODMs on merchant silicon
Licensing and support renewals tied to vendor-controlled refresh cycles
Feature licensing: coherent optics, timing, advanced routing sold separately
Vendor lock-in: single source for hardware refresh and roadmap
Vendor-specific management ecosystems: limited automation portability across vendors
✓   OcNOS-SP on Open Hardware
Broadcom / Marvell merchant silicon, significantly lower CapEx vs. proprietary
Single IPI support contract covers software, hardware, and RMA
Full SP feature stack in the SKU: no per-feature license tax
Multi-vendor hardware support: Edgecore, UfiSpace, and HCL partners
Linux-based, open APIs: full NETCONF/YANG, gNMI, RESTCONF, OpenConfig

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.

FAQ

Frequently asked questions

What is SR-MPLS and how does OcNOS-SP implement it?
Segment Routing (SR-MPLS, RFC 8402) embeds forwarding instructions directly into the packet label stack, eliminating the need for LDP and RSVP-TE. OcNOS-SP implements SR-MPLS with IS-IS/OSPF SR extensions, Flex-Algo (RFC 9350) for constraint-based path computation, and TI-LFA for sub-50ms loop-free fast reroute, providing simpler operations, faster convergence, and native traffic engineering.
Does OcNOS-SP support 400G ZR+ optics for IPoDWDM?
Yes. OcNOS-SP natively manages 400G coherent pluggable optics (OpenZR+ and OIF 400ZR) in QSFP-DD form factor, eliminating standalone transponder shelves. Modulation, FEC, pre-FEC BER, OSNR monitoring, and laser tuning are all configurable from the standard OcNOS CLI. Validated transceiver partners include Ciena (WaveLogic 5 Nano, up to 1800 km), Furukawa, SmartOptics, Hisense Broadband, Coherent Corp, and NEC.
Does OcNOS-SP support IEEE 1588v2 for 5G timing?
Yes. OcNOS-SP supports IEEE 1588v2 PTP with ITU-T G.8265.1, G.8275.1 (boundary clock), and G.8275.2 profiles combined with SyncE (G.811). On validated compact platforms like the UfiSpace S9501-28SMT, this achieves sub-100ns Class C and Class D phase accuracy, required for 5G NR fronthaul, midhaul, and backhaul. OcNOS-SP is TIP DCSG compliant.
Which SKU matches my role: core router, cell-site gateway, or IPoDWDM edge?
SP-IP-BASE covers L2/L3 routing, EVPN-VXLAN, and streaming telemetry, typical for access and aggregation. SP-MPLS adds the full MPLS stack including SR-MPLS, SRv6, EVPN L2VPN/L3VPN, MEF 3.0 Carrier Ethernet: this is the core router baseline. CSR is the Cell Site Router tier: IEEE 1588v2 timing, SyncE, TIP DCSG compliance for 4G/5G xHaul. SP-PLUS unlocks 400G ZR/ZR+ coherent optics for IPoDWDM and DCI. See the OcNOS Feature Matrix for the full breakdown per platform.
Can I migrate an existing IOS-XR or Junos config to OcNOS-SP?
OcNOS-SP uses an industry-standard CLI designed to minimize retraining for engineers coming from IOS-XR, Junos, or Nokia SR OS. IP Infusion professional services provide config translation, design validation, and migration runbooks for Tier-1 and regional operators moving production traffic off proprietary chassis. Contact the IPI team via Contact to scope a migration for your topology.
What hardware platforms does OcNOS-SP run on?
OcNOS-SP runs on 40+ validated open hardware platforms from Edgecore, UfiSpace, and EPS Global, based on Broadcom Qumran 2 family (Q2U, Q2A), Jericho 2C+, and Trident 4 chipsets. Platforms range from compact cell-site gateway form factors to 14.4T core routers with 400G ZR+ coherent optics. See the full Hardware Compatibility List, or read the per-chip silicon deep-dives for spec details and SP role recommendations.
Is OcNOS-SP a viable alternative to Cisco and Juniper?
Yes, OcNOS-SP is a carrier-grade alternative to Cisco IOS-XR and Juniper Junos, supporting SR-MPLS, BGP, MEF 3.0 Carrier Ethernet, and IEEE 1588v2 timing on your choice of open hardware. It is in production with 600+ operators in 60+ countries who replaced proprietary chassis to lower TCO and avoid vendor lock-in. See the OcNOS vs Juniper comparison or read the customer stories from operators who replaced their IOS-XR or Junos backbone.
What is the OcNOS-SP support model?
OcNOS-SP customers receive a single-vendor support contract from IP Infusion covering software, hardware (when sold as an OcNOS System), and RMA logistics. 24/7 TAC, hardware advance replacement, and a customer support portal are included. Migration consulting, design validation, and topology runbooks are available as professional services. See Support or OcNOS Systems for details.
