Carrier-Grade Core Infrastructure

OcNOS® brings the power of disaggregation to the Service Provider Core. By combining a mature, field-proven network operating system with high-performance whitebox silicon, OcNOS delivers terabit-scale routing, uncompromised resilience, and massive CapEx and OpEx reductions compared to legacy chassis-based routers.

Terabit-Scale Capacity

Scale your backbone to 400G and 800G gracefully to handle the explosive bandwidth demands of 5G, FTTH, and AI-driven cloud traffic.

Maximum Resilience

Ensure 99.999% network availability with deep hardware buffers, Non-Stop Routing (NSR), Graceful Restart, and sub-50ms Fast Reroute (FRR).

IPoDWDM Integration

Collapse your IP and Optical layers natively. OcNOS seamlessly integrates 400G/800G ZR and ZR+ coherent optics directly into the router.

Streamlined Operations

Automate end-to-end provisioning and monitoring using standard NETCONF/RESTCONF, OpenConfig YANG models, and rich Streaming Telemetry.

Key Core Capabilities

Core Network Architecture

High-capacity, scalable open networking architecture converging on an OcNOS-powered core fabric.

1. IP/MPLS Backbone Routing
OcNOS delivers a robust routing stack for massive core deployments, supporting millions of IPv4/IPv6 routes in the hardware FIB. It offers carrier-proven BGP, IS-IS, and OSPF implementations with advanced traffic engineering to optimize backbone link utilization.

2. Segment Routing (SR-MPLS)
Transition from legacy protocols to an agile, modern core. OcNOS supports comprehensive SR-MPLS capabilities, eliminating the overhead of LDP and RSVP-TE while delivering granular source-based routing, traffic engineering (SR-TE), and automated sub-50ms protection via TI-LFA.

3. Peering & Internet Exchange (IXP)
Purpose-built for peering edges and IXPs, OcNOS handles full Internet tables with ease. Ensure network security and optimal peering with advanced BGP policy filtering, RPKI origin validation, BGP Flowspec, and EVPN for highly scalable Layer 2 interconnection.

4. Data Center Interconnect (DCI)
Extend Layer 2 and Layer 3 services securely across your wide-area network. OcNOS leverages EVPN-VXLAN and EVPN-MPLS to create scalable, multi-tenant DCI links that guarantee low latency, high throughput, and seamless workload mobility.

5. Precision Timing & Synchronization
Distribute hyper-accurate timing across your core infrastructure. OcNOS supports Class C/D hardware with PTP (IEEE 1588v2) and SyncE, ensuring that your transport network meets the strict synchronization requirements of 5G Advanced and O-RAN deployments.

Choose Your Core Platform

ASIC Architecture System Capacity Port Density Primary Core Application
Jericho2C+ (J2C+) 14.4 Tbps 100G / 400G High-Density Core, Carrier Backbone, IPoDWDM
Jericho2 (J2) 4.8 Tbps / 9.6 Tbps 100G / 400G Core Routing, Peering, DCI
Qumran2C (Q2C) 2.4 Tbps / 4.8 Tbps 100G / 400G Metro Core, Peering Edge
Tomahawk 3 / 4 12.8 Tbps – 25.6 Tbps 100G / 400G Core Spine, High-Density DCI Fabric

*Hardware specifications are dependent on specific ODMs (e.g., UfiSpace, Edgecore). OcNOS SP-PLUS license required for advanced SR-MPLS, EVPN, and 400G ZR/ZR+ features.
