Network Deployment Tiers

Where in your network does OcNOS-SP operate?

Select a tier to see specific protocols, platform options, and deployment evidence.

Provider Edge & IP Core

Internet-scale routing. Open silicon. No proprietary lag.

The IP core demands full BGP table scale, sub-second failure recovery, and traffic-engineered paths — all at multi-terabit density. OcNOS-SP delivers this on Broadcom Qumran 2A and Jericho 2C+ silicon, matching legacy proprietary core router capabilities at open hardware economics.

SR-MPLS with Flex-Algo & TI-LFA

RFC 8402 Segment Routing with IS-IS/OSPF SR extensions. Flex-Algo (RFC 9350) for constraint-based path computation. TI-LFA sub-50ms loop-free fast reroute — eliminates legacy RSVP-TE complexity.

BGP Full-Table at Internet Scale

2M+ routes on Broadcom Qumran2, multi-hop eBGP, RPKI origin validation, BFD sub-second detection, wire-speed ECMP across 64 equal-cost paths for load balancing to multiple peering partners.

Core / PE Platforms

License Tier

IP core deployments use OcNOS-SP PLUS — the full feature tier unlocking advanced analytics, IPoDWDM management, and full BGP table scale on the same hardware.

Metro Transport & IPoDWDM

Eliminate the transponder chassis. Route and light wavelengths from one CLI.

IP over DWDM converges routing and optical into a single control plane. OcNOS-SP natively manages 400G coherent pluggable optics directly through the routing CLI — collapsing the traditional transponder chassis and reducing metro infrastructure cost by up to 60%.

OpenZR+ & OIF 400ZR Management

Configure modulation (DP-16QAM to DP-QPSK), FEC mode, laser frequency tuning, and monitor pre-FEC BER, OSNR, and chromatic dispersion — all from standard OcNOS CLI without a separate optical element manager.

MEF 3.0 Carrier Ethernet

E-Line, E-LAN, E-Tree, and E-Access services. OcNOS-SP is the first open NOS MEF 3.0 certified. ITU-T Y.1731 OAM for strict metro SLA monitoring.

The full IPoDWDM story — validated transceiver ecosystem, platform tables, DCI use cases — is on the dedicated solution page.

Metro / IPoDWDM Platforms

Cost Impact

Eliminating transponder shelves at metro nodes reduces per-site footprint and power by 30–40%. At 10 nodes, typical hardware CAPEX savings reach $2–5M.

TIP DCSG & 5G xHaul

Precision timing at the cell edge. No dedicated timing appliance.

5G NR requires sub-100ns phase alignment at every base station. OcNOS-SP implements the full TIP DCSG specification on compact, low-power open platforms — delivering IEEE 1588v2 Class C and Class D accuracy directly from the routing layer, without separate timing hardware at every site.

IEEE 1588v2 Class C/D Timing

ITU-T G.8265.1, G.8275.1 (boundary clock), G.8275.2 profiles. SyncE G.811 for frequency. Sub-100ns phase accuracy for 5G NR fronthaul and midhaul — validated on compact open hardware.

TIP DCSG Compliance

Full DCSG specification: L3 routing, SR-MPLS, HQoS, and BGP signaling for mobile xHaul aggregation. Single-vendor solution covering both software and compact open hardware.

EVPN Multi-homing (ESI)

Standard-based EVPN Ethernet Segment Identifiers for all-active multi-homing — sub-second redundancy for cell sites without proprietary MLAG.

DCSG Validated Platforms

Field Evidence

Mobile operators using OcNOS-SP on UfiSpace compact platforms have validated sub-100ns phase accuracy for 5G NR — bypassing dedicated hardware timing appliances entirely.

BNG & Access Aggregation

Per-subscriber shaping at line rate. Deep-buffer silicon. Open economics.

Broadband aggregation requires intensive per-subscriber traffic management. OcNOS-SP delivers hierarchical QoS and EVPN-VXLAN on deep-buffer merchant silicon — handling microbursts from gigabit PON networks without packet drops, at materially lower cost-per-subscriber than proprietary BNG chassis.

Hierarchical QoS (HQoS)

Per-subscriber traffic shaping and scheduling at line rate on deep-buffer Qumran silicon. Enforces tiered broadband plans without external policy servers.

EVPN-VXLAN Aggregation

Modernize legacy L2 rings with EVPN-VXLAN or MPLS data planes. Multi-tenant broadband traffic isolated end-to-end without forklift of existing OLT infrastructure.

For ISPs, WISPs, FTTx operators, and middle-mile transport, the Broadband & Access solution page covers the full deployment stack.

Technical Insights

Common questions from SP network architects

OcNOS-SP is IP Infusion's carrier-grade, disaggregated network operating system for service provider networks. It eliminates the core problem: proprietary vendor platforms force SPs to accept hardware lock-in, 6-month lead times, and fragmented software stacks across each network tier. OcNOS-SP runs on validated open whitebox hardware and delivers the full SP protocol stack — SR-MPLS, EVPN, IEEE 1588v2 precision timing, MEF 3.0, and IPoDWDM — from a single consistent platform, at 60–70% lower CAPEX.
Yes. OcNOS-SP is deployed in production at over 600 operators globally, including Tier 1 service providers, as a replacement for Cisco IOS-XR (ASR 9000, NCS 540/560) and Juniper Junos (ACX series). It delivers equivalent carrier-grade capabilities: BGP full-table (2M+ routes), SR-MPLS, EVPN, HQoS, MEF 3.0 Carrier Ethernet, and IEEE 1588v2 Class C/D timing. Engineers familiar with Cisco IOS or IOS-XR find the CLI immediately familiar — zero retraining overhead.
Traditional MPLS requires LDP and RSVP-TE for path signaling — significant control-plane complexity and state. Segment Routing (SR-MPLS, RFC 8402) eliminates both by embedding forwarding instructions directly into the packet label stack. Simpler operations, faster convergence, and native traffic engineering without pre-provisioned tunnels. 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.
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 and midhaul. OcNOS-SP is TIP DCSG compliant, making it a validated open replacement for proprietary cell site gateway hardware.
A validated platform means IP Infusion and the ODM hardware partner have jointly lab-tested the platform for full OcNOS-SP compatibility, production stability, and feature parity. IP Infusion provides a single support contract covering both OcNOS software and open hardware — one escalation path, no vendor finger-pointing. Hardware vendors include Edgecore and UfiSpace, with 2-week standard lead times versus 6+ months for proprietary chassis.
Flex-Algo (RFC 9350) extends IS-IS and OSPF to define custom shortest-path algorithms based on constraints — latency, bandwidth, administrative colour, or TE metrics. An SP can define one Flex-Algo for low-latency traffic and another for high-throughput traffic, computing separate virtual topologies over the same physical infrastructure. No additional overlay protocols or hardware required.
OcNOS-SP uses a progressive tiered model: IPBASE (L2/L3 routing), MPLS (label switching and VPN services), CSR (cell site gateway, TIP DCSG, Class C/D timing), and PLUS (full feature set including IPoDWDM and advanced analytics). Operators start at IPBASE and unlock higher tiers as network requirements grow — software-only upgrades on the same validated hardware.
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. For the full IPoDWDM architecture, platforms, and validated transceiver ecosystem, see the dedicated IPoDWDM solution page.
